What is the different between bellow globe valve and bellow gate valve? 1. The bellow seal globe valve more longer then bellow seal globe valve, so pipe line prefer to choice bellow globe valve. 2. Different flow and functions, bellow seal globe valve can not only be used as a cut-off, but also can be used to regulate and control the pressure flow. The bellow seal gate valve is usually used for isolation. Bellow seal globe valve no need full open，the gate valve generally needs to be fully opened or closed. 3. Different installation methods When use bellow globe valve, the medium can generally be from top to bottom. When medium flow in bellow seal gate valve, there is no no requirement on the direction of import and export. 4. When the bellow seal globe valve working, its handwheel and valve stem are generally rotating together, and will do the lifting action together, the bellow gate valve generally only the handwheel will rotate, besides it only do the lifting action.

Hunter is an old purchaser of EAGLE PRO company in Canada. It has been several years since he purchased hydraulic directional control valves from AAK. In the second half of last year, Hunter emailed that he would become the general manager of Hangzhou branch in a month and visit AAK. Hunter has been engaged in procurement for 5 or 6 years. This promotion must be due to outstanding contributions. Some time ago, their company developed a batch of hydraulic cylinders, which vibrated greatly during commissioning. Their engineer thought that there was a problem with the hydraulic directional control valve, but the hydraulic directional control valve was normal when tested separately. The engineer was confused, and the boss was also very anxious. He asked hunter to consult the manufacturer of hydraulic directional control valves. This hydraulic directional control valve is produced by a local factory in Canada. After on-site analysis, the engineer of the original factory thinks that the vibration is caused by the sharp change of oil port pressure during the reversing of the hydraulic directional control valve. It can be solved by changing the hydraulic manifold design. The engineer's scheme is to connect two small adjustable one-way throttle valves in series on the control oil circuit at both ends of the hydraulic direction control valve. After 20 days, according to the plan of the original hydraulic directional control valve manufacturer, there was no vibration. The boss was very happy and let Hunter be promoted. Knowing that the installation of two throttle valves has increased their cost by 20%, I wonder if there is any other scheme. After getting their hydraulic direction control valve drawings, hydraulic manifold drawings and the hydraulic schematic diagram of the system, AAK engineers began to analyze. Three days later, AAK's scheme came out. The shoulder of the hydraulic directional control valve spool table was redesigned and a triangular throttling groove was added to avoid the sharp change of oil port pressure during reversing. This new design does not change the production cost of the hydraulic directional control valve, that is, it solves the vibration at zero cost. Hunter was a little incredible and asked AAK to immediately sample the new hydraulic direction control valve. One month later, the hydraulic directional control valve of AAK sample was sent out. After commissioning, there is no vibration, but the cost is zero. Hunter's boss happily saved 20% of the cost and asked hunter to always send inquiry for any hydraulic directional control valves to AAK at the first time. The design of hydraulic directional control valve runs through the whole process of design, manufacturing, use and maintenance. A good hydraulic directional control valve design cannot be separated from manufacturing. AAK engineers consider not only manufacturing, but also the function and performance of the hydraulic directional control valves, even innovation. The innovation of this hydraulic directional control valve adds a new element of triangular throttling groove on the original basis. Hunter privately informed that the boss was very satisfied that he solved the problem with 0 cost. He deserved the position of general manager of Hangzhou branch, and he worked harder and harder. AAK hydraulic directional control valve, advanced to solve problems with 0 cost, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valve- aak239

David from Israel collaborated with hydraulic cartridge valve manufacturers in China since 2018. AAK has supplied him with several hydraulic cartridge proportional valves that are equivalent to HydraForce standard parts, and it has always been very smooth. In May of this year, a hydraulic cartridge directional valve with high requirements for cylindricity made him very upset. This hydraulic cartridge directional valve is used in hydraulic systems for navigation, with high accuracy requirements, especially the cylindricity accuracy cannot exceed 3μm. David disliked the high price of AAK, and chose another hydraulic cartridge directional valve manufacturer in Ningbo China. Later, I learned that it was just 12% higher. I told David that there are no more than 3 manufacturers in Ningbo that have this program, but not every manufacturer can control the cylindricity of each hydraulic cartridge directional valve cylindricity accuracy within 3μm. Last week, David emailed me to check if AAK can control the cylindricity accuracy of each hydraulic cartridge directional valve within 3μm. After communication, it was learned that his procurement from the other hydraulic cartridge directional valve manufacturer was not smooth. The cylindricity of the manufacturer's hydraulic cartridge directional valve hole is unstable, although most of the accuracy can be within 3μm, those unqualified hydraulic cartridge directional valves, which are not sensitive to opening and closing, have affected the entire hydraulic system. Their engineers require that the accuracy of each hydraulic cartridge directional valve hole be controlled within 3μm. The manufacturer requested a 30% increase in price because the 30% of unqualified hydraulic cartridge directional valves will be wasted. I told David that whether the cylindricity accuracy of the hydraulic cartridge directional valve hole is stable or not depends on the machining. But each one needs to meet accuracy of within 3μm, the key lies in 100% detection, and a high sensitivity cylindricity measuring instrument is required. AAK can control the cylindricity accuracy of each hydraulic cartridge directional valve hole to be 2μm, which is higher than 3μm accuracy that he requested. The detection of the cylindricity accuracy of the hydraulic cartridge directional valve hole is carried out by AAK using the Japanese Mitutoyo measuring instrument and connected to the roundness analysis software. The measurement data and graphics can be summarized and analyzed first, and then the detection results can be obtained. Especially, the Z-axis comes with a digital ruler, with a rotation accuracy of up to (0.04+6H/10000) μm. Equipped with DAT function (digital adjustment function), it avoids errors in adjusting the instrument manually and ensures timely screening of each substandard valve hole cylindricity. Most hydraulic cartridge valve manufacturers in China do not use this testing instrument and may not conduct 100% full inspection. AAK hydraulic cartridge directional valve, valve hole cylindricity accuracy, not only in processing, but also in testing, you can also give it a try!

A few days ago, an Indian friend browsed AAK hydraulic valve website and left a message: Your experience is very similar to mine. AAK's content promotion on the internet has impressed him and he also wants to try content marketing. I'm not sure if he's in the hydraulic cartridge valve industry. Before answering his question, let's first explore the marketing of hydraulic cartridge valve content. What is content marketing? How to do it? There are many ways to promote content marketing. Today, taking the AAK official website and the release of B2B as an example, I will share my experience and mindset in the hydraulic cartridge valve industry. 1. The content of hydraulic cartridge valves requires a true long-term perspective. We need to first think clearly, why do we need to do the content of hydraulic cartridge valves? What is the purpose? The purpose of AAK is to increase the credibility of hydraulic cartridge valves and cultivate trust. Imagine, there is a person who encountered a problem in purchasing hydraulic cartridge valves and nothing has been effectively resolved. What should he do? He would almost certainly search for the words "hydraulic cartridge valve" on Google, to see if there are any suggestions for solving the problem, or other hydraulic cartridge valve manufacturers. After searching, he found that out of the 100 articles, 10 were all customer cases from AAK hydraulic cartridge valves. At this point, he will leave an impression that AAK is a bit professional, and then he opens these 10 articles and takes a look, feeling that the explanation is very reasonable. So he thought, 'I want to contact AAK”. This is to increase credibility and establish AAK's trust in potential hydraulic cartridge valve customers. In this process, my deepest feeling is that the content of hydraulic cartridge valves must be a true long-term perspective. So, I have always believed that only by creating truly original and valuable hydraulic cartridge valve content can it be a friend of time. 2. Build trust with the density of time and the thickness of content. What exactly should we do? How can trust be established? AAK focuses on 2 things: the density of time and the thickness of content. If I have any hydraulic cartridge valve content that I want to write, I write it, update it if the content is good, and not update it if I don't want to write it or if the content is not good. Can we do this way? No. Daily update is necessary. Now those who do a few hours of live streaming every night, as long as they stop for a day, users may be taken away. The daily update of AAK hydraulic cartridge valve content is to cultivate user habits, otherwise everyone will forget about AAK. Its significance and value lie in using a sense of companionship to cultivate the habit of continuously reading hydraulic cartridge valve content together, giving users certainty. After outputting a large amount of content, AAK hydraulic cartridge valves have accumulated over 550 articles. These contents have thickness in the field of hydraulic cartridge valves. After this thickness accumulates, the sense of existence becomes stronger and difficult to be replaced. The advantage of the internet is that everything exists there, it has sediment and will not disappear. So, it must be more. Be sure to be thick. AAK uses the thickness of the hydraulic cartridge valve content to establish professionalism and recognition in the field of hydraulic cartridge valves, in order to increase AAK's trust. The more stored, the thicker the content, and the greater the influence. It is a forward flywheel. 3. The promotion is spreading everywhere, and there are AAK hydraulic cartridge valves everywhere on the internet The content of AAK hydraulic cartridge valves is launched on 40 B2B platforms every day. The density of time, the thickness of content, the viscosity of promotion, and the explosiveness. Good content may not necessarily lead to ultimate success, but without it, it is definitely not possible. Persist in continuous output, high-quality output, and store content of sufficient thickness in the field of hydraulic cartridge valve industry. Thank you for reading the article. Thank you for being with us. Let's continue to serve hydraulic cartridge valve industry together, think together, and grow together. AAK hydraulic cartridge valve, engaged in it for another 50 years.

Barnabas is from Pakistan, and has cooperated with AAK for 4 years. Some time ago, he contacted me and needed my help to customize a 1+1=1 hydraulic threaded cartridge valve. They have a hydraulic manifold developed by themselves. The customer feels that the manifold is too complex in the selection of cartridge valves. Their engineers asked to integrate the functions of the hydraulic relief valve and flow control valve into a hydraulic threaded cartridge valve. The cartridge valves in the manifold are all standard parts from HydraForce. For multi-functional hydraulic threaded cartridge valves, HydraForce has no time to customize it. After discussion, AAK engineers decided that it is feasible to combine the functions of relief valve and flow control valve into a hydraulic threaded cartridge valve. After 45 days, AAK sent 20 hydraulic threaded cartridge valves. Last week, Barnabas sent an email asking me to prepare the production plan of 500 hydraulic threaded cartridge valves in advance. Their manifold was recognized by customers. Their engineers were satisfied with the dual-function of AAK hydraulic threaded cartridge valves. AAK hydraulic threaded cartridge valve can not only adjust the system pressure, but also realize the easy unloading of the oil circuit when the multi-way valve stops working. Our engineers have made 3 innovations, which most cartridge valve manufacturers can hardly think of at the same time. 1. Change of valve spool: there are pilot valve spool and main valve spool, and there are 3 through grooves connected in turn. The main valve spool is at the front end of the pilot valve spool, located in the first passage slot, and the length is less than the length of the passage slot. The pilot valve spool is located in the third pass slot, the convex part passes through the second pass slot and extends into the first pass slot, and the convex slope matches the slope of the second pass slot. 2. Spring change: there is a main spring in the main valve spool. One end of the spring is against the main valve spool and the other end is against the valve housing. The outer side of the pilot valve spool is sleeved with a pilot spring. One end of the spring is against the bulge at the front end of the pilot valve spool, and the other end is against the locking structure at the rear end of the pilot valve spool. 3. Change of through-hole: the valve housing is provided with a first through- hole and a second through-hole. The first through-hole corresponds to the position of the pilot valve spool, and the second through-hole corresponds to the position of the main valve spool. The front end of the main valve spool has a filter pad, the side wall of the main valve spool has a third through hole, the front end of the main valve spool has a fourth through hole, and the filter pad has a fifth through hole. The optimized hydraulic threaded cartridge valve, when the multi-way valve stops working, the pilot valve spool moves towards the main valve spool, and the main valve spool moves towards the front end, so that the second through hole corresponds to the third through hole. The hydraulic oil passes through four through holes, replacing the functions of relief valve and flow control valve, and realizing unloading. AAK hydraulic threaded cartridge valve, replaces the relief valve and flow control valve, with 2 in 1, save you money.

At the beginning of March this year, Bartolomeo said in an email that he would like to make an appointment to consult AAK about hydraulic manifold problems. Bartolomeo, from Italy, is the purchasing manager of Italpresse Industrie Shanghai Branch. According to the communication, their company developed a hydraulic die-casting machine at the end of last year. The sales volume is just so. The general feedback is that the equipment has high energy consumption and low production efficiency. Their engineers pondered for more than 2 months, but couldn't find the reason, and the boss also had a big headache. Bartolomeo felt that the hydraulic manifold design dragged down the equipment and consulted the original hydraulic manifold manufacturer. However, the manufacturer could not put forward constructive opinions on the hydraulic manifold design. Bartolomeo thought of AAK, because AAK had proposed to modify the oil circuit when receiving the inquiry about the hydraulic manifold. According to the design drawings and system schematic diagram of hydraulic manifold provided by Bartolomeo, AAK engineers closed the door and discussed for 3 days, basically found out the direction, and it is 90% determined that there was a deviation in the oil circuit design of the original hydraulic manifold on the hydraulic die casting machine. There is an energy conflict between the original hydraulic manifold oil circuit aperture and the hydraulic valve used, resulting in the slow response of the hydraulic system and the need for additional energy to maintain the operation of the system, resulting in high energy consumption and low production efficiency. AAK can redesign the hydraulic manifold oil circuit and send hydraulic manifold samples within 30 days. Bartolomeo was very happy that AAK found the cause of hydraulic manifold problem at once. The situation was fed back to the boss, who immediately paid for AAK to redesign and test samples. A month later, AAK sent out the whole newly designed hydraulic manifold. Two weeks later, Bartolomeo emailed to order 20 hydraulic manifolds first to replace those ones on the equipment complained by customers. I was surprised that there was no comment on AAK hydraulic manifold samples but received the urgent order first. Bartolomeo advised that according to the comparison of their engineer’s on-site test run, the die casting machine with AAK hydraulic manifold has a sensitive response, the working efficiency is 11% higher than before, what’s more, the energy consumption is reduced by 30%. Their boss asked to order some hydraulic manifolds for emergency use first, and then replace all hydraulic manifolds on the original equipment with AAK shipments. AAK has professional engineers with more than 20 years of industry experience from German HAWE company, they have unique experience in hydraulic manifold design, especially in oil circuit design. Combined with the system principle, through the change of the installation form and working area of the hydraulic valves and the innovative and optimized design of the oil circuit of the valve block, and the development and application of new materials, we can produce high-efficiency, energy-saving and durable hydraulic manifolds. You may not find a second such hydraulic manifold manufacturer in Ningbo. The day before yesterday, Bartolomeo advised that the customer was very satisfied with the die casting machine replaced with new hydraulic manifolds and was ready to re purchase the equipment. The boss was very satisfied that he spontaneously sought the hydraulic manifold manufacturer to solve the old problems. The boss was going to promote him to take full charge of the work of the Shanghai Branch. AAK hydraulic manifolds make your equipment efficient and energy-saving. You can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak238

Whether it's a hydraulic cartridge valve manufacturer or other manufacturers, there are always competitors who see you as their competitor. What should be done when a hydraulic cartridge valve manufacturer encounters face-to-face provocation from an opponent and the customer is present? A few days ago, a Russian old customer visited hydraulic cartridge valve manufacturer AAK. After the meeting, he asked me to take him to another hydraulic cartridge valve manufacturer. After arriving at the factory of the another hydraulic cartridge valve manufacturer, I waited downstairs. One hour later, the other party's boss accompanied the customer to the car, and we were ready to leave. When the other party's boss saw that it was me, he said to the customer: It's time for dinner and I’d like to invite both of you to have a meal together. The customer didn't say anything and looked at me. The problem is that competitors invite you to dinner. Are you going or not? 90% of the hydraulic cartridge valve manufacturers would said NO, but I promised to dinner together. Everyone is hungry, and I will pay in advance and make the other party owe me a favor. At that time, I asked him where to have the dinner? I drive, one car is enough. The other party said to go to a five-star hotel, and added, "You've never taken a client to such a high-end place, have you?". As soon as I heard it, the fire started to ignite, but I quickly calmed down. I said that according to the personal preferences of our clients, going to that place for dinner is not very interesting. Today, you come with me. I know there is a private customized small courtyard, and many times, even if you pay, you may not be able to have a dinner. It must be a VIP with more than 3 years of experience. During the meal, that hydraulic cartridge valve manufacturer did not give up and continued to provoke. He asked me suddenly, how is engineer Mr. Liu going on in your factory? I asked what happened. He said that Liu was an employee who was laid off by their factory, and added another sentence, “AAK took over the employee who were laid off by us.”. The customer also looked at me, and I casually said, "You need to reflect on this. Such an excellent talent cannot be retained by your factory. You need to consider your own system and process of the hydraulic cartridge valve manufacturer. Where the problem is?". In the face of provocation, how to solve it, I think it's very simple. Just use "pick it up" and he says no matter how bad you are, you can pick it up. The higher you praise, the more embarrassing the other person will fall. Dealing with provocations from competitors, it is the worst for a hydraulic cartridge valve manufacturer to argue with them.

Last week Grossman placed an order for 1,500 hydraulic cartridge valves at one time. I'm not surprised at all. At the Shanghai PTC exhibition the year before last, I met Grossman from a Russian company and talked for more than 30 minutes at the exhibition. After the exhibition, Grossman informed by email that a newly developed hydraulic equipment of their company needs hydraulic cartridge valves, and 20 hydraulic cartridge valves from AAK were tested. This is a non- standard customized hydraulic cartridge valve. After we delivered the goods, Grossman didn't send any email to feed back the situation of AAK goods for half a year. A year later, Grossman placed the reorder of 200 hydraulic cartridge valves of the same model, and there was also no news after delivery. In 2 years, there were only two small orders of hydraulic cartridge valves, but I have a feeling that Grossman is further deeply testing AAK hydraulic cartridge valves. It was not until last week when there was a large order for hydraulic cartridge valves placed, Grossman then started to describe the ups and downs of purchasing hydraulic cartridge valves in Ningbo. In the past 2 years, Grossman found more than 20 hydraulic cartridge valve manufacturers for sample testing and was cheated by some new hydraulic cartridge valve manufacturers. The quality of the test order was OK, but the reorder was complained by customer. For hydraulic cartridge valves purchased from some other factories, there were always complaints after a period of time, such as several leaks or jamming, insensitive opening and closing or serious wear etc. The 2 batches of hydraulic cartridge valves from AAK have not received any complaint in 2 years, which is why he decided to order large quantities of hydraulic cartridge valves from AAK. After 2 years of comparison among more than 20 hydraulic valve manufacturers, Grossman found that only AAK hydraulic cartridge valves are 100% qualified. His boss also agreed that the future hydraulic cartridge valves will only be purchased from AAK. No customer complaints with AAK hydraulic cartridge valves, that is because AAK has 3 advantages. There may be no second manufacturer in Ningbo who can have the following 3 points at the same time. 1.AAK hydraulic valve has high-precision CNC machining centers, machine tools and other equipment imported from Switzerland, as well as various independent fixtures upgraded and refitted by himself, which eliminates human errors. At the same time, the management of every detail of the processing, production, assembly, inspection and packaging of each hydraulic cartridge valve has been accurately controlled. 2. AAK uses pneumatic measuring instrument to test the accuracy of each processed valve sleeve, while most manufacturers use sampling test. During the assembly of accessories, the accuracy of the fit clearance between each valve spool and valve sleeve is tested again with a pneumatic measuring instrument. 3. After assembly, carefully check whether the accessories are complete, and test each hydraulic cartridge valve, including leakage, flexibility, opening and closing performance etc. AAK hydraulic cartridge valves have conquered Russian customer with 3 facts leading domestic peers. You can also try one order. https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valves-aak237

Richard, a hydraulic customer from Bolivia, failed to purchase hydraulic cartridge relief valves from China for the first time. Richard has purchased hydraulic components from local hydraulic cartridge valve manufacturers in Bolivia for 3 years. He heard from his peers that the cost performance of purchasing from China is better than that of Bolivian hydraulic valve manufacturers, so he began his overseas procurement trip. A hydraulic cartridge relief valve with rated pressure exceeding 30MPa, and the fit clearance between valve body and valve spool is required to be 0.006~0.01mm. Richard successively tried samples with 3 hydraulic cartridge relief valve manufacturers in 70 days. The hydraulic cartridge relief valve samples had either internal and external leakage, blocked oil circuit, or even stuck. 3 times of proofing failed, which made Richard helpless and even suspected that he was misled by his domestic peers. Richard noticed AAK on the B2B website and saw some tweets and customer cases to solve the problems of hydraulic cartridge valves, especially some big brands such as HydraForce and SUN Hydraulics, are also loyal customers of AAK for many years. He seemed to see hope and left a message to us: How much MPa can the rated pressure of the hydraulic cartridge relief valve with a clearance of 0.006~0.01mm between the valve body and the valve spool be? When I saw this message, I subconsciously felt that he had stumbled in the accuracy when purchasing this hydraulic cartridge relief valve, and he was inexperienced in choosing the hydraulic cartridge valve manufacturer. According to the problems of his hydraulic cartridge relief valve samples, AAK technical team determined that the problem was caused by burrs inside the hydraulic cartridge relief valve. However, the specific problem still depends on the sample analysis. I suggested Richard making samples directly to see the manufacturing quality of AAK hydraulic relief valves. Maybe that will change his view on China hydraulic cartridge valve manufacturers. After 30 days, AAK sent 10 samples of hydraulic cartridge relief valve. 6 months later, Richard emailed us that AAK hydraulic cartridge relief valves did not have the problems of "internal and external leakage, or blockage of the oil path or stagnation" that occurred in other hydraulic cartridge valve manufacturers, which also strengthened his confidence in purchasing from China hydraulic cartridge valve manufacturers. How to effectively avoid burrs of hydraulic cartridge relief valves? It is also a "thorn" that AAK has to remove since it was engaged in the R&D and manufacturing of hydraulic components. With 13 years of manufacturing experience, AAK can be sensitive to find problems and solve them. In the processing of hydraulic cartridge relief valves, the undercut of the main valve hole is the place where the most burrs are generated. The traditional processing technology is: first rough boring, then semi fine boring, then milling the undercut, and finally reaming. The burr generated after reaming is in the same direction as the axis line of the hole, and is sunk in the undercut, which is difficult to remove completely. AAK has already optimized the process route: first rough boring, then semi fine boring, then reaming, and finally milling and sinking the groove. The burr generated is perpendicular to the axis line, and there is no dead angle, which is easy to observe and remove. AAK hydraulic cartridge relief valve, no burr, no leakage, no clamping stagnation, welcome to try the order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak406

This Monday, we launched a solenoid proportional valve equivalent to HydraForce standard part SP08-21. The features of this solenoid proportional valve: Continuous-duty rated coil. Efficient wet-armature construction. Optional waterproof E-Coils rated up to IP69K. Industry common cavity. Compact Size. The function of this solenoid proportional valve: A solenoid-operated, 2 port, normally open, poppet type proportional, screw in hydraulic cartridge valve designed for low leakage in load-holding applications. When de-engergized, the SP08-21 allows flow from 2 to 1. Flow from 1 to 2 is severely restricted. When the valve is partially energized (see performance curve) the valve begins to throttle flow from 2 to 1. When fully energized, the valves poppet closes on the seat, blocking flow from 2 to 1. The cartridge will allow 1 to 2 flow after overcoming the solenoid force. AAK has received 5 inquiries for this solenoid proportional valve within only 3 months, from May to July 2023, with 3 customers placed trial orders. This hydraulic solenoid proportional valve is not only widely used, but also has multiple functions, especially its good performance. Although some China hydraulic cartridge valve manufacturers can produce this hydraulic solenoid proportional valve, and its functions may also be compared to HydraForce standard part SP08-21, their solenoid proportional valve performance may be a problem. AAK hydraulic cartridge solenoid proportional valve 2 advantages: 1. Internal leakage: 5 drops/min, benchmarking against HydraForce 2.

Early March this year, Austin from Canada left a message on AAK website: AAK hydraulic valves have been used in aviation field, can you produce hydraulic relief valves with the valve body produced by nickel titanium alloy? For similar messages, I basically reply that if there is a need, I will directly sampling the hydraulic relief valves. Whether it can meet the standard is not determined by mouth, but by data. After communication, it was learned that their company has a power unit used in the aviation hydraulic system, and the customer requires that the test run be completed within 3 months. Austin contacted an old supplier of hydraulic relief valves with the best quality, and the supplier promised to deliver 20 samples of high-precision hydraulic relief valves within 40 days. After 20 days, the manufacturer of the hydraulic relief valves can't bear it. In particular, the valve body of the hydraulic relief valves is made of nickel titanium alloy. During processing, the cutting tools were changed for 5 times, and 80% of the products were still scrapped. Austin had to find a new manufacturer of hydraulic relief valves. He contacted some new manufacturers in a few days, they either have no confidence in the hydraulic relief valves used in the aviation field, or no reply at all. Austin saw in Google that AAK hydraulic valve supplied to military enterprises and aerospace equipment, and realized that maybe AAK can help solve the dilemma of hydraulic relief valves. According to the hydraulic relief valve drawings and working condition requirements emailed by Justin, AAK engineers found that this hydraulic relief valve is just similar to the one supplied to Russian customer last year. The difference is the valve hole size. It only needs to make small modifications to the process procedure, and 20 hydraulic relief valve samples are sent out after 15 days. Two months later, Austin informed by email that the commissioning of the equipment was very smooth with the use of AAK hydraulic relief valves. AAK was the only one of more than 10 hydraulic relief valve manufacturers he contacted, who dared to make samples directly and completed the non-standard hydraulic relief valves in 2 weeks. Their engineers were surprised to have such a magical hydraulic relief valve manufacturer. The non-standard hydraulic valves were completed in 2 weeks, which most hydraulic valve manufacturers can't do unless there are similar procedures. AAK has a number of non-standard hydraulic valve procedures. The key reason why AAK hydraulic relief valves can be supplied to military enterprises and aerospace fields is the following 3 points. There may not be a second hydraulic relief valve manufacturer in Ningbo that can meet the 3 points at the same time. 1. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control. 2. AAK has a high-precision CNC machining center imported from Switzerland and Kennametal combined tool imported from the United States. This tool has the best cutting ability for NiTi alloy with very high toughness and strength, and has high advantages in life, performance, efficiency and stability. 3. AAK test equipment has 5 pressure test benches that can operate independently of each other, and each test area is equipped with professional inspectors, so as to ensure that each hydraulic relief valve is qualified before shipment. AAK high precision hydraulic relief valves can be used in aviation hydraulic system. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak236
