This valve complies with API 600, API 6D, and ASME B16.34 standards, offering reliability and performance. Available in sizes ranging from 2 to 48 inches and with class ratings of 150-1500 LB, it is crafted from carbon and stainless steel. Trust our commitment to quality for your through conduit parallel disc slab gate valve needs. I. Through Conduit Gate Valve Introduction The through conduit gate valve is a sliding valve whose gate is a parallel gate. The shutter can be a single shutter plate or a double shutter plate with a deployment mechanism in between. The push force of the gate to the valve seat is controlled by the pressure of the medium acting on the floating gate or floating valve seat. If the through conduit gate valve is a dual shutter through conduit gate valve, the spreading mechanism seen in the two shutters can compensate for this pressure. 1. The valve seat adopts the floating valve seat structure with o-ring sealing and pre-tightening force, and the inlet and outlet of the flat gate valve are sealed in both directions; in addition, the switching torque of this structure is 1/2 of that of the ordinary valve, and the valve can be easily opened and closed. 2. When the flat gate valve is fully opened, the channel is smooth, the flow resistance coefficient is extremely small, and there is no pressure loss, and the pipeline can be cleaned with a hair ball 3. The filling material structure with self-sealing ability is adopted, which does not need to be adjusted frequently, the switch is extremely light, and the sealing performance is reliable. The auxiliary sealing grease injection structure is set at the filling material, the sealing performance is absolutely reliable, and zero leakage is truly achieved; It solves the disadvantage that the general valve packing is most likely to leak. 4. When the through conduit gate valve is closed, the high pressure in the inner cavity can be automatically eliminated, which is convenient to use. 5. The fully enclosed structure has good protection performance and can meet all- weather requirements. Ⅱ. Applicable Occasions for Through Conduit Gate Valve 1. Class 150 - 900 LB/PN1.0~16.0 MPa (working temperature is -29~121 ℃) oil and natural gas transmission pipeline. The flat gate valve with pilot port also facilitates cleaning of the line. 2.

Carter comes from an excavator manufacturing company in Italy, and the purchase of hydraulic needle valves has been smooth in recent years. At the beginning of last year, an excavator sold by their company for less than 6 months was complained by customer. The boom of the excavator falls too fast due to its own weight, which is easy to cause danger. Their technician found that there was a problem with the hydraulic needle valve of the hydraulic system. There were obvious wear marks at the contact point between the valve spool and valve seat of the hydraulic needle valve, which was easy to leak. The leakage of the hydraulic needle valve will cause the oil saving and speed limiting circuit of the hydraulic cylinder to be uncontrollable. The boss was very angry that the equipment sold for only half a year was complained and asked Carter to find out the cause of the hydraulic needle valve problem and solve it. Carter contacted the original manufacturer of the hydraulic needle valves and requested to replace the hydraulic needle valves. The manufacturer said that the service life of hydraulic needle valves under 450bar working condition is basically 6 months. The only way to solve this complaint is to replace the hydraulic needle valves every 6 months. Such reply made Carter speechless, because his customer would not accept the high-frequency replacement of hydraulic needle valves, which not only brought a bad user experience, but also the after-sales cost was not cheap. Carter contacted all of his hydraulic needle valve suppliers, and they all replied that they were not sure to achieve a hydraulic needle valve with a service life of 1 year under the working condition of 450bar. When browsing the website, he found AAK and left a message on the website: How long is the service life of hydraulic needle valves with pressure resistance of 450bar? We replied directly for 1 year or more. The next day, he told the problems encountered in purchasing hydraulic needle valves at the beginning of last year in detail. After receiving the drawing of the hydraulic needle valve, we found that the hydraulic needle valve needed by Carter has much higher requirements than the ordinary hydraulic needle valves. We replied that AAK will select specific materials for samples, which can ensure that the hydraulic needle valves can be used for more than 1 year under normal conditions. If possible, he can directly test the samples. One month later, AAK sent 24 hydraulic needle valve samples. A year later, Carter sent an email saying that the excavator with AAK hydraulic needle valves still have not encountered boom problem yet. Among all of his hydraulic needle valve suppliers, only AAK has a service life of more than 1 year. The surface treatment of the valve body of AAK hydraulic needle valves adopts electromagnetic induction heating. Its main advantages are fast heating speed, light oxidation and decarburization of the workpiece surface, and the surface hardening layer can be adjusted according to needs, which is easy to control. The hardened layer has fine martensite structure and high hardness, strength and toughness. After surface quenching, the surface of the workpiece has large compressive internal stress, and the fatigue breaking resistance of the workpiece is high. Using induction heating surface quenching, the number of fatigue cycles under design load is about 10 times higher than that with ordinary quenching and tempering treatment. AAK hydraulic needle valves, special material selection, high pressure resistance and durability, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak183

Caleb is an old customer of AAK in Mexico and has purchased hydraulic cartridge valves from AAK for 4 years. At the end of last year, he emailed me to discuss 3 issues related to hydraulic pilot operated relief valves. 1. The internal leakage of AAK hydraulic pilot operated relief valve cannot exceed 1 drop/min. 2. Can AAK hydraulic pilot operated relief valve achieve multi-level pressure control? 3. Can AAK hydraulic pilot operated relief valve be customized within 35 days? Looking closely at these 3 questions, I guess he encountered a problem when purchasing a hydraulic pilot operated relief valve. After communication, it was learned that in September, they developed a multifunctional excavator. Due to time constraints, Caleb purchased the hydraulic cartridge valves from a local hydraulic cartridge valve manufacturer in Mexico, but the test run was not successful. Because the internal leakage of the hydraulic pilot operated relief valve is not up to standard, multi-level pressure control also fails, resulting in a weak excavator and unstable operation. After being optimized by the original hydraulic pilot operated relief valve manufacturer, it still failed to meet the standard, so Caleb wanted AAK to try this hydraulic pilot operated relief valve. AAK engineer's opinion: the valve sleeve and adjusting sleeve of the original hydraulic pilot operated relief valve are the same part. The valve spool is installed from the oil inlet end of the valve sleeve, and then blocked by a retaining ring. The valve spool and valve sleeve are sealed by a gap, which is the source of non-compliance. After discussing with their engineers, Caleb asked AAK to sample in this direction. After 35 days, AAK sent 10 samples of hydraulic pilot operated relief valves. 4 weeks after the samples were sent, Caleb informed us that AAK hydraulic pilot operated relief valve was installed in the system, which solved the problem of causing the excavator to become weak, and the multi-level pressure control function was also available. Yesterday, Caleb emailed us an order for 160 hydraulic pilot operated relief valves. He told me, this is the first order from this customer. His boss is very satisfied with AAK hydraulic piloted operated relief valve, which has the performance advantage of internal leakage, as well as multi-level pressure control feature, allowing them to obtain customer order for excavators. AAK hydraulic piloted operated relief valve, with internal leakage of 1 drop/min, and can achieve multi-level pressure control functions. Starting with the sealing method, we divide the valve sleeve and adjusting sleeve of the hydraulic relief valve into 2 parts. The valve sleeve and valve spool are sealed with a cone, as follows: 1. The valve spool of the hydraulic relief valve is located inside the valve sleeve, and the adjusting sleeve and the valve sleeve are fixedly connected in a bayonet type. The spring is inside the valve spool, with one end against the valve seat and the other end against the bottom of the valve spool. 2. The other end of the valve seat is against the pilot valve spool inside the adjusting sleeve, and there is a pressure regulating spring inside the pilot valve spool. The valve sleeve has 2 step through-holes in the axial direction. The junction between the large hole and the small hole is processed into a conical surface, and the valve spool and valve sleeve are sealed at the conical surface. 3. A radial hole for oil control passage is provided between the valve spool and the valve seat. There is a steel ball between the valve seat and the pilot valve spool. There is a circular hole on the valve seat that communicates with the radial hole to accommodate the steel ball, and there is a blind hole on the pilot valve spool to accommodate the steel ball. AAK hydraulic piloted operated relief valve, internal leakage of 1 drop/min, and multi-level pressure control function, you can also try it! https://www.aakindustry.com/info-detail , /relief-valves-aak538

Mateo comes from a Canadian company specializing in food hydraulic equipment. The hydraulic relief valves he needs are not to be used in traditional machinery or equipment. He pays special attention to the cleanliness of the hydraulic relief valves. Last week, he sent an email saying that he would order 2,000 hydraulic relief valves at one time, because the customer placed a large order for the equipment newly developed by his company at the end of last year, and his boss repeatedly stressed that he must purchase from AAK only. Mateo gave AAK a trial order of 20 hydraulic relief valves in the second half of last year, and specifically noted that the parameters of this hydraulic relief valve should not be careless, because it is related to the sales of their new equipment. At the same time, pay attention to the cleanliness of the hydraulic relief valves, because this equipment is used in the food assembly line. I replied to him at that time that you can rest assured of the quality of AAK hydraulic relief valves. You can compare with several manufacturers at the same time, and let the results to speak. Several months after the samples of hydraulic relief valves were sent, Mateo didn't reply. During this period, we also sent several emails to follow up, but no any news, it's like a stone sinking into the sea. At that time, I thought he found a better manufacturer than AAK hydraulic relief valves. I didn't expect that 6 months later, Mateo immediately placed the big order of the hydraulic relief valves, which really surprised me. I asked Mateo why your boss decided to place such a big order for AAK hydraulic relief valves. Mateo said that during sample stage for the hydraulic relief valves, they selected 6 manufacturers and started installation and commissioning after receiving the samples. Except for one hydraulic relief valve manufacturer, the parameters of the other 5 manufacturers were qualified. They decided to choose a hydraulic relief valve with the lowest price to test the machine. The hydraulic relief valves stuck in 3 months, affecting the operation of the equipment. After disassembling the valve body, the engineer found that there was fine sand like dirt on it, which should be caused by dust pollution on the hydraulic relief valves. The manufacturer believes that the dust pollution on the hydraulic relief valves is caused during transportation, which has nothing to do with them. The engineer suggested using AAK hydraulic relief valves to test the machine instead. In more than half a year of debugging, there was no stuck problem. The boss said that although the price of AAK hydraulic relief valves was a little higher than that of other factories, the details of their dust-free packaging were amazing. Compared among 6 hydraulic relief valve manufacturers, only the packaging of AAK surprised everyone. When we know the equipment is to be used in the food production line, we know that the cleanliness of the hydraulic relief valve is strict. We did these things: 1. The components of hydraulic relief valves are cleaned with ultrasonic cleaning equipment after processing; 2. In the assembly workshop, automatic induction setting is adopted for the entrance and exit, and workers are not allowed to go in and out unless necessary, so as to avoid dust pollution of the packaging site. 3. After the hydraulic relief valves pass the quality inspection, put each one into a single layer thickness of 0.12mm polybag and seal it. 4. Put it into the injection molded PP plastic box, and then in inner packaging and outer packaging. 100% dust free protection during transportation. AAK hydraulic relief valves, dust-free packaged, used in food equipment, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak182

Recently, the PO quantity of AAK hydraulic pressure regulating valves has suddenly increased. Whether it is the trial order or the daily order of wholesale customers, after the delivery date of the hydraulic pressure regulating valves is determined, the customers begin to pay. Brooke is my old customer. We have cooperated for more than 1 year. Most of his orders are hydraulic pressure regulating valves. Yesterday, Brooke placed a new test order and advanced the full amount. I asked him why he chose to give it to AAK. Brooke replied to us as follows: 1. AAK gives as much as it promises, unlike other hydraulic valve manufacturers who over promise but can't fulfill the commitment. 2. In the technology of hydraulic pressure regulating valves, I trust AAK most. 3. In terms of service details, AAK is the best in my current hydraulic valve supply system. My first business with Brooke was also the hydraulic pressure regulating valve. The first PO was a small order for the hydraulic pressure regulating valve. The second time, there was an inquiry for a large number of hydraulic pressure regulating valves, and we also made samples, but Brooke told me that because the price of AAK was 17% higher than that of another hydraulic pressure regulating valve manufacturer in Ningbo, so he purchased it from another factory. I remember that I joked: if there is no problem with the hydraulic pressure regulating valves you purchased, I will admire you. At that time, he needed a hydraulic pressure regulating valve with high pressure parameters. There may not be a third hydraulic pressure regulating valve manufacturer in Ningbo who can meet this parameter. As expected, Brooke said in an email last month that he was trapped by another manufacturer of hydraulic pressure regulating valves in Ningbo. After the goods arrived, the workshop technicians installed the hydraulic pressure regulating valves and began to increase 20% of the rated pressure for pressure test. After 24H, some hydraulic pressure regulating valves leaked. However, in the approval stage, the samples of hydraulic pressure regulating valves from this factory were up to standard. Brooke contacted the manufacturer of the hydraulic pressure regulating valves, but manufacturer replied that there was no stock to replace them. Brooke replaced the hydraulic pressure regulating valves with samples from AAK originally, and there was no leakage problem under the same working conditions. Finally, AAK adjusted the production schedule specially and produced new goods for him, which completely solved the leakage problem of the hydraulic pressure regulating valves. I told Brooke that to meet the requirements of this high-pressure working condition, special attention needs to be paid on not only the material selection, but also the material heat treatment and workpiece processing accuracy. More importantly, each hydraulic pressure regulating valve should pass the high-pressure test bench. AAK has a self-developed high-voltage test bench, which can accurately test each hydraulic pressure regulating valve to ensure 100% qualification. There may not be a third one like us in Ningbo. In the hydraulic valve industry, customers who leave due to price may still come back. Most customers who leave due to service will not turn back, and customers who leave due to quality will never come back. AAK hydraulic pressure regulating valves have so many repeat customers up to now, it is precisely because AAK always puts the quality requirements at the first place, strictly controls every detail, and does not ship until it passes inspection 100%. AAK hydraulic pressure regulating valves, the parameters are guaranteed to meet the standard, pay close attention to service details. You are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-regulating-valves- aak181

One morning last month, Antonio emailed us that there was a problem with AAK hydraulic directional control valves purchased some time ago, and a problem was found in the factory commissioning of the bending machine. The starting pressure of the hydraulic system of the bending machine will suddenly increase. Their engineers think it is caused by the instability of the hydraulic direction control valves and ask us to replace it. I'm totally confused. Because this hydraulic directional control valve is produced and inspected in full accordance with the parameters provided by Antonio, and the parameters of the hydraulic directional control valve are approved in the commissioning stage of the bending machine. Antonio is from Prada Nargesa company in Spain. He has cooperated with AAK on hydraulic directional control valves for several years. This is the first complaint from him. In the sample stage, Antonio informed that this hydraulic direction control valve was used in the hydraulic system of the bending machine produced by his company. It was noted that the bending tonnage was required to be 400 tons, the maximum bending length was 6 meters, and the bending accuracy was +/- 0.3°. The pressure and accuracy requirements of the hydraulic direction control valve were very high. After our internal discussion, we found the problem strange. AAK engineer asked Antonio to send a video of the working condition of the hydraulic system of the bending machine for us to check what the problem is. Through the video, we found that there was a problem about the installation position of the needle valve of the integrated valve block of the hydraulic system and the position of the hydraulic directional control valve. It was preliminarily judged that the pressure regulation mode of the hydraulic system of the bending machine is not correctly designed, and this hidden danger will come out after more than 8 hours of continuous test run. But the designers of their company didn't agree with our proposal and thought we were shifting the responsibility. I suggest Antonio give us 30 days to redesign the integrated valve block. If there are still problems after installation, AAK is willing to bear all costs. Considering that these bending machines are in a hurry to ship, it will take longer time if purchasing new hydraulic directional control valves, moreover it is not guaranteed that the new hydraulic directional control valves will be no problem, Antonio reluctantly agreed with AAK proposal. After 25 days, AAK sent out the integrated valve block with hydraulic directional control valve, which was installed and debugged for more than 8 hours. Everything of the bending machine was normal, and their designers had to affirm it. AAK professional engineers designed the pressure regulation of the hydraulic system of the bending machine as a modular type, and rearranged the position of the needle valve and the hydraulic direction control valve, so as to provide the proportional regulation function. At the same time, the unloading circuit is simple and reliable. The safety pressure valve is connected in parallel in the lower chamber of the oil cylinder to form a double safety circuit to prevent the abnormal rise of the oil pressure in the lower chamber from damaging the oil cylinder and pipeline, so as to ensure the safety of the equipment. Antonio told us privately that a similar situation happened the year before last. The hidden danger of the original design of the equipment is simply considered to be the problem of the supplier's hydraulic directional control valve. Even they changed 3 manufacturers of hydraulic directional control valves, problem was still not solved. AAK hydraulic directional control valve can give technical support that peers can't give. You are welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valves- aak180

There is an old Chinese saying “Good wine needs no bush”. The meaning is that my product is very good and I am not afraid that no one will buy it. This saying is a bit out of place now. For hydraulic manifold manufacturers, if your quality is stable but without any dissemination, no customer knows where your hydraulic manifold manufacturer is. Some hydraulic manifold manufacturers know that their quality is average, and their sales concepts are that relationships and lower prices can make up for it. Such sales concepts are not beneficial for both hydraulic manifold manufacturers and customers. For a hydraulic manifold manufacturer, how can be good salesperson, or what are the advantages that good salesperson should have? I learned from a small story that a good salesperson needs to have curiosity and participation. A sales representative of an airline, his major client gave him an inquiry. Tomorrow afternoon at 4 o'clock, 20 people from the client company will rush to Beijing for a meeting. They will be flying on the same plane, with a model requirement of 787. Everyone needs a seat on the aisle side, and each person will have an additional fruit meal. The budget cannot exceed 800 yuan. The first reaction of the salesperson was that they couldn't accept this order because their airline had a 380 model and didn't have a 787 model. An hour later, the salesperson was curious about why the customer insists on the Boeing 787, so he communicated with the customer. The customer said it was a large airplane, so the salesperson sent him photos of the cabin of their Airbus 380 model, and asked the client, ’Is it such a large airplane?’ The customer said yes. The salesperson is motivated, following closely with the second question, ‘why do 20 people have to sit on the same plane?’ The customer said it's convenient to be together, but the salesperson said that there are 20 people sitting on the same plane in the same company. From a risk perspective, it is possible, but from a probability perspective, it is almost non-existent. However, let's be more meticulous in our work and minimize the risk as much as possible. In case the boss is concerned with details. The customer said, it makes sense, listen to you. This salesperson was curious and actively involved, reaching a consensus with the buyer and landing the order. Buyers send inquiries to hydraulic manifold manufacturers, and there are many different roles for buyers, some are bosses, some are engineers, and some are just purchasers. Especially or a purchaser, his execution of the company's procurement work is based on personal consciousness. For example, in the story above, why do all people need a seat on aisle side? I think it's so comfortable, but in fact, among the 20 people, some prefer to lean against the window. The salesperson of hydraulic manifold manufacturers should be driven by curiosity, understand why customers have this requirement, communicate with customers, express concern, translate their "I think" into details, be understanding, and participate. Even if there is a budget conflict, there is still a possibility of increasing the budget. What's really important when flying to a meeting is to be on time. In order to arrive on time, there is a possibility of increasing the budget. Sometimes what buyers want is not necessarily cheap, it may be a sense of presence, security, achievement, or taking advantage of. If you want to satisfy their feeling of taking advantage with cheap, no matter how cheap you are, it cannot dispel the buyer's "I think". Customers always hope to get more and give less. If we treat the buyer's stated needs as real needs without considering their personal cognition, then this communication cannot reach the point, where all needs are executed through people. Without understanding the other party, it is difficult to have in-depth communication. The 2 common points of good salesperson for hydraulic manifold manufacturers are curiosity and participation, which need to keep up. Only by following up can there be a chance. Finding the truth about the problem and solving it requires resources. Resources are not what you need to have, but what the customers that you serve need. No matter what kind of customer, they are all role aware in an objective environment, and their needs are determined by their role. There are 2 types of resources: one is called heavy resources, which hydraulic manifold manufacturers can directly help customers achieve, and the other is called light resources, which hydraulic manifold manufacturers can help customers know how to achieve. However, this is lacking for the salesperson of most hydraulic manifold manufacturers. To express concern, interact with customers, and utilize your heavy resources to inspire your light resources. This kind of salesperson is what hydraulic manifold manufacturers and customers need.

This Monday, we launched a hydraulic cartridge pilot operated relief valve equivalent to HydraForce standard part RV12-26. It is a screw in, cartridge style, pilot operated (two stage), spool type relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis. The features of this hydraulic cartridge pilot operated relief valve: Adjustments cannot be backed out of the valve. Adjustments prohibit springs from going solid. Hardened spool and cage for long life. Optional spring ranges to 240 bar (3500 psi). Rapid, smooth response to pressure surges. Cost-effective cavity. A hydraulic cartridge valve customer in Russia placed a test order for 10 pcs last January in 2022. After 1 year of testing, it proves that the function and performance of AAK hydraulic pilot operated cartridge relief valve benchmarked the quality of HydraForce RV12-26.

Some time ago, an old customer in the United States needed us to sign a confidentiality agreement to develop a new hydraulic relief valve. The drawings of the hydraulic relief valve were sent 1 month after the confidentiality agreement was signed. The customer requested that if we were not able to develop it, they would witness us destroy the drawings and documents of the hydraulic relief valve by video. It's the first time for this customer to be so formal. After receiving the drawings of hydraulic relief valve, we knew that it was to match with a set of aerospace equipment developed by a world top 500 enterprise in the United States. AAK engineers reviewed the drawings for 3 days and still didn't write the sample program. This hydraulic relief valve is not only small in size, but also has material requirements, machining accuracy requirements and use frequency requirements that exceed the parameter requirements of the hydraulic relief valves we have seen. We estimated that the overall development cost will not be less than 20,000 US dollars, and the success rate will be about 10%. When we mentioned the development cost and difficulty to the customer, the customer's answer is: now I'll give you 30,000 dollars and give you 1 year of time. If the development is successful, you can wait for the order of hydraulic relief valve. If the development fails, this $30,000 will be deducted from the payment for AAK in the future. That’s to say that the customer will prepay for the development cost of the hydraulic relief valve, but if it fails, we will need to refund it by deducting from the future payment gradually. I did not hesitate to reply to the email and was willing to try to develop this hydraulic relief valve. Our engineer joked that next, it is estimated that he will lose a layer of skin. If it fails, it may be not only a waste of tens of thousands of dollars in development costs, but also the loss of his own job. I told him that the success of the hydraulic relief valve development would be counted as the contribution of the technical team, and the failure would be counted as mine, because I can't fail to live up to the customer's support for our development. Some people in AAK can not understand how this could be a kind of support. Maybe he didn't think about a question, that is, what would the mentality of the technical team be without customer support? Behind these are two completely different ways of thinking. One is that if you haven't done it yet, think about failure first, think about whether there is a bottom plan first, and if not, don't do it. There is also a way of thinking, which is to think about how to start first. If conditions permit, start working first. The difference between these two ways of thinking is not just the difference between conservative and radical, but whether people are the key factor to create value. With the starting money, the hard work of the technical team and the best logistics support of AAK, the probability of successful development of hydraulic relief valve may be high. AAK hydraulic relief valve, no matter how difficult it is, just do it first. You are welcome to give it a try. https://www.aakindustry.com/info-detail/hy , draulic-relief-valve-aak179

Divyesh is from a hydraulic equipment manufacturing company in Pakistan, and has 3 years of procurement experience smoothly. In the second half of last year, their ultra-high pressure forging press was complained by customers that the equipment was shaking. After checking, it was found that the hydraulic cartridge pressure control valve was abnormal and difficult to adjust the pressure, resulting in large system pressure fluctuations and equipment jitter. The original manufacturer of the hydraulic cartridge pressure control valve tried to improve it, but the effect was general. The trouble was that there were more and more similar complaints. Divyesh had a very big headache. Divyesh found AAK on Google and stayed on AAK hydraulic valve website for more than 10 minutes. Perhaps AAK customer cases of optimizing the hydraulic valve stimulated him and he sent us an email asking: 1. Can AAK make the pressure adjustment of hydraulic cartridge pressure control valve convenient? 2. How does AAK control the pressure fluctuation of hydraulic cartridge pressure control valves? 3. How long does AAK need to optimize the original hydraulic cartridge pressure control valve? After communication, I learned about Divyesh's dilemma. According to his original drawings and the schematic diagram of the hydraulic system of the ultra-high pressure forging press, AAK engineers found that the problem could be solved by optimizing the structure of the original hydraulic cartridge pressure control valve. After 35 days, AAK sent 12 samples of hydraulic cartridge pressure control valves. 3 months later, Divyesh informed by email that AAK hydraulic cartridge pressure control valve had been used for 3 months, the customer had no complaints about the forging press shaking. AAK hydraulic cartridge pressure control valve has stable pressure control and convenient pressure regulation, and their engineers are very satisfied. AAK hydraulic cartridge pressure control valve is mainly composed of valve body, booster valve spool, external control valve spool and spring. Our engineers have made 3 unique structures for the original hydraulic cartridge pressure control valve, which most hydraulic cartridge valve manufacturers may not expect. 1. The booster valve spool is T-shaped, and the area of one end connected with the spring is twice that of the lower end. The valve spool is equipped with a damping hole extending from the load end to the spring end. The internal pressure on one side of the spring is lower than the inlet pressure, that is, a smaller pressure is used to control a larger pressure, which plays the role of boosting, and the pressure adjustment is convenient. 2. The external control valve spool is connected by a pipeline at one side of the spring. The valve spool is I-shaped and is equipped with a T-shaped damping hole, which can make the oil in the compression part press out of the valve body, effectively maintaining the stability of the external control valve spool. 3. On the same side of the valve body of the hydraulic cartridge pressure control valve, there are oil inlet holes and oil outlet holes. The oil inlet holes are connected through pipelines. The valve body is equipped with a connection hole at the end of the oil outlet hole. When the load oil pressure is too large, the upper limit of the oil pressure balance can be carried out to meet the working condition requirements under ultra-high pressure. AAK hydraulic cartridge pressure control valve, high pressure and large flow are also stable, you can also have a small try! https://www.aakindustry.com/info-detai , l/pressure-control-valves-aak461

Monroe is from Sweden and has been purchasing hydraulic threaded cartridge valves from Ningbo for 3 years. In January of this year, their customer wanted to place a repeat order for one of their hydraulic unit equipment, but requested a 20% price reduction. Monroe wanted to reduce the price of the check valve, relief valve, and solenoid unloading valve in the hydraulic unit by 30% to meet customer requirement, but the original hydraulic threaded cartridge valve manufacturer cannot accept the new price. Monroe contacted AAK for inquiry. When I saw his target price, I directly informed him that this price could not be achieved. Monroe did not give up and emailed me again. After communication, it was learned that his customer requested a 20% price reduction for the equipment. I felt a bit strange, but immediately realized that last November, AAK customized an integrated multi- function hydraulic threaded cartridge valve for a Spanish customer, replacing the 3 standard hydraulic threaded cartridge valves in their hydraulic systems. I suggested him sending me the schematic diagram of their equipment hydraulic system for a look. At first, he wasn't willing to do so, but when I sent him the customized case for this Spanish customer, he immediately compromised. After discussion, AAK engineers found that Monroe's problem was similar to that Spanish customer. As long as the functions of the check valve, relief valve, and solenoid unloading valve in the equipment are integrated into a hydraulic threaded cartridge valve, not only can cost be reduced, but also the hydraulic oil circuit is more simplified. After 45 days, AAK sent 10 samples of hydraulic threaded cartridge valves. Last week, Monroe emailed me that AAK hydraulic threaded cartridge valve was installed on their hydraulic unit, and the equipment functionality was not affected. He gave the customer a 30% discount, and the customer was surprised by the extra 10% discount and pleased to place the repeat order. Monroe told me that AAK multifunctional hydraulic threaded cartridge valve allows him to earn an additional 15% more in profits, his customer gets additional discounts, and AAK also has a new customer. I am happy to do things that benefit all 3 parties. 1. The hydraulic threaded cartridge valve sleeve is provided with a communication valve hole, a working port of the oil cylinder, a hydraulic control port of the oil tank, an oil inlet port, and an oil return port. A check valve spool is provided in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized, replacing the check valve of the original structure. 2. The hydraulic threaded cartridge valve is provided with an overflow valve spool, which connects the valve hole and the oil return port to provide a damping hole for unloading. At one end of the damping hole, there is an unloading valve spool that controls the opening and closing of the damping hole and the oil return port. The check valve spool is provided with a connecting channel that connects the valve hole and the working port for overflow or unloading. This achieves the unloading function, replacing the original structure of the solenoid unloading valve. 3. When the check valve spool is separated from the working port, the oil inlet port and the working port are connected to the unloading hydraulic control valve spool, and the connection between the valve hole and the overflow valve spool of the oil return port can also be disconnected. This achieves the overflow function and replaces the original structure of the relief valve. AAK hydraulic threaded cartridge valve, 3 in 1 function, saving over 40% cost for customer, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-valves-aak537
