Hydraulic Cartridge Pressure Control Valve Special Spool Machining Skill
A while ago, there was an international parcel from Brazil on my desk. I thought it was from an old Brazilian client, Machado, who sends AAK hydraulic cartridge valves that need to be developed every month. That day, I was a bit busy and forgot to unpack the package. It wasn't until the next day that I received an email from Brazil that I learned it was a hydraulic cartridge pressure control valve sample sent by a new customer, Faba, as well as a specially designed valve spool. Faba mentioned in the email that he found hydraulic cartridge valve manufacturer AAK in China on Google and asked if AAK could customize the special valve spool of this hydraulic cartridge pressure control valve. After communication, we learned that he encountered a problem with the valve spool accuracy not meeting the standard when purchasing this hydraulic cartridge pressure control valve from the original manufacturer. Due to its unique shape and accuracy of within 2μm, the original manufacturer failed 3 times. I was curious why it is necessary to have a specially designed valve spool to match this hydraulic cartridge pressure control valve. Faba did not discuss it much, perhaps there are trade secrets or patents. He only asked, can AAK try a sample? Although we were not 100% certain, Faba's contempt has ignited our engineer's desire for challenge. We first thought about the materials and chose alloy steel with the same hardness but easy to machine. On the premise of ensuring the overall size of the valve spool, a rotary material reduction processing method is adopted to lay a solid foundation for the next step of grinding. The key lies in the presence of Japan's Mitutoyo contour measuring instrument to constantly check whether the accuracy under special shapes meets the standards After 50 days, 6 hydraulic cartridge pressure control valve samples were sent out. 6 weeks later, Faba informed us via email that although AAK changed the spool material of the hydraulic cartridge pressure control valve, the accuracy was within 2μm. The valves have been working for 4 weeks and no leakage was found yet. As long as the service life of the hydraulic cartridge pressure control valve reaches 12 months, they can fully promote their equipment. Meanwhile, Faba emphasized that the spool of this hydraulic cartridge pressure control valve cannot be revealed to any third party. For this hydraulic cartridge pressure control valve, I would like to summarize the AAK inspection and the customized fixture combined with the special shape of the valve spool to ensure that there is no deviation in the rotation of the valve spool. After installing the valve spool into a customized fixture, set a speed of 50mm/s, start the measuring instrument, and the built-in contact needle starts 360 degrees, and detects the surface geometry of the valve spool through multiple cycles. Due to the special shape of the valve spool, changes in its geometric shape cause displacement of the contact needle. The generated analog signal of the surface contour ratio is automatically converted into a digital signal, which is then collected and integrated into the program for automatic comparison. The core of testing is not only the customization of fixtures, but also the setting of rotational speed, which needs to be explored based on the surface geometry of the valve spool. The hard power of AAK is reflected in these soft actions. Most hydraulic cartridge pressure control valve manufacturers mechanically refer to the user manual of the measuring instrument during the testing process. AAK hydraulic cartridge pressure control valve, hard power, soft action, you can also give it a try!

AAK Hydraulic Flow Control Valve, 3drops/min High Precision
Margaret, from India, is an old hand in the procurement of hydraulic components, especially good at price reduction, and has little cooperation with AAK, basically small quantities of high requirement hydraulic valves. 1 year ago, she wanted us to develop a high requirement hydraulic flow control valve and promised that there will be big qty of reorders. After the trial order was sent, there was still no reorder, and I didn't want to push. In her email last month, she said that 160 hydraulic flow control valves tested last year were needed, and the price was required to be maintained and the fastest delivery time was required. This hydraulic flow control valve was used in hydraulic bending machine equipment, and the early test run was very smooth. The equipment was sold very well. Unexpectedly, 3 months later, customers complained about the weakness of the hydraulic system of the bending machine. Some valve spools and valve bodies of the hydraulic flow control valves were worn, causing leakage, resulting in the weakness of hydraulic system of bending machine. The original hydraulic flow control valve manufacturer believed that the bending machine was used with high frequency, so a small proportion of wear was normal, but Margaret's supervisor didn't think so. He predicted that there would be more and more complaints later. In fact, what his supervisor predicted was right. Margaret had to change the manufacturer. She contacted many manufacturers, but none of them was willing to develop it because of the small quantity or they couldn't meet her requirements. Margaret was worried at this time. Until receiving her email, I just knew that this hydraulic flow control valve had reorders, but were not placed with AAK, she came to me this time because she had no way. Frankly speaking, although AAK had existing procedures, I didn't want to produce this order for 160 pcs of quantity. It was not until her boss found my boss 3 days later that I gave a 1 month production time and a 50% increase in the quotation. Margaret still approved our S/C. She was criticized by her boss because they not only lost the payment to the original hydraulic flow control valve manufacturer, but also undertook an additional 50%. I estimate that Margaret will never dare to transfer the order of AAK again. I was thinking that if your hydraulic valve manufacturing quality and service level are high, in the communication with customers, you can be polite and dignified, neither humble nor overbearing, otherwise the customers don't take you seriously. The business should be done standing. Although AAK price of this hydraulic flow control valve has been increased by 50%, it has taught Margaret and me a lesson. I sent out 160 hydraulic flow control valves in only 2 weeks. Margaret was very grateful for my advance shipping, and we had mended the fences between us. It took us 2 months to test the sample of this hydraulic flow control valve. We knew its difficulties, and we solved it with 3 points: 1. The valve spool is made of 20CrNi2MoV high carburized bearing steel from Germany. Through secondary quenching + cryogenic treatment + low temperature tempering process, the molecular structure of the material is improved, the microhardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times. 2. Swiss machine tools are used for processing, coupled with AAK's own modified fixtures, human errors are eliminated. 3. We can achieve 3drops/min for this hydraulic flow control valve, which is benchmarked with HydraForce, while most peers can only achieve 5drops/min. AAK hydraulic flow control valve is not only wear-resistant, but also leak free. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak285 Contact:

AAK Hydraulic Flow Control Valve Can be Used in Aviation Field
At the beginning of this year, Hedwig sent an email asking for an ultra-high precision hydraulic flow control valve, with drawings and working conditions attached. Hedwig comes from an Italian hydraulic equipment company and has been cooperating with AAK for some years. In the second half of last year, they planned to bid for a power unit for aviation hydraulic system but was blocked by the hydraulic flow control valve. The cylindricity of valve sleeve inner hole should be within 1μm, and the leakage during operation is absolutely not allowed to exceed the specified value. Hedwig found a hydraulic flow control valve manufacturer in Italy to test the sample. 1 month later, the equipment was debugged, but the accuracy of inner hole of hydraulic flow control valve sleeve was not up to standard, and the leakage volume exceeded the specified 30%. Hedwig contacted several non- standard customized manufacturers, but the cylindricity of the inner hole could only be in the range of 2-3μm. After more than 2 months, no progress had been made, and all components were complete, except for the hydraulic flow control valve. The bidding time was coming, and the boss was very unhappy. Hedwig was under great pressure. Hedwig thought of AAK, because only AAK met the requirements of the previous hydraulic valves with high accuracy. Later, I replied him that according to the drawings and parameter requirements of this ultra-high precision hydraulic flow control valve, AAK needed at least 45 days to complete the sample production. Hedwig said it was acceptable. After 40 days, AAK sent 20 samples of hydraulic flow control valves. 1 month later, Hedwig emailed that thanks to AAK ultra- high precision hydraulic flow control valve, the company won the bid. Hedwig told me privately that his boss was very satisfied with his purchasing work this time, and said that he would double the year-end bonus this year. He also wanted to know why so many manufacturers can't do it, but AAK can? I told him that the cylindricity of the inner hole of AAK hydraulic flow control valve sleeve was within 1μm by virtue of the following unique 3 points: 1. The process is the key and the technology is the core of the processing of valve sleeve inner hole. AAK adopts 6 process steps: deep hole drilling pre- holing, vacuum quenching, rough honing, semi fine honing, artificial aging treatment and fine honing, while most manufacturers can only do 3 steps. 2. AAK adopts American precision honing machine to hone the inner hole for 3 times, including rough honing, semi fine honing and fine honing, ensuring the cylindricity of the inner hole is in the range of 0.4-0.75μm. 3. Mechanic operation is also the most important, AAK adopts dedicated person and machine, not to say that human-machine integration, but at least as proficient as just like the left hand touching the right hand. AAK hydraulic flow control valve, can be used in aviation field. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak284 Contact:

AAK Hydraulic Pilot Operated Cartridge Relief Valve 3 Skills
Today is the first day of CNY's return to work. I opened mailbox and was full of surprises, especially the Mexican customer Chandler that we followed up for more than 1 year, placed an order, a large order of 1,200 hydraulic pilot operated cartridge relief valves. This is the happiest thing today. Chinese people pay attention to a good start, which represents hope, and also luck. 2023, I'm coming. A year ago, Chandler left a message on AAK Hydraulic Valve website: Can AAK ensure that the hydraulic pilot operated cartridge relief valve is stable and fault-free within 1 year? As soon as I saw this message, I guessed that he was troubled by the quality of the hydraulic pilot operated cartridge relief valve. After communication, it was learned that the cartridge relief valve produced by the original manufacturer was unstable and had a service life of less than 6 months, which caused their hydraulic winch to be complained because of its unstable operation and inability to rise. According to the drawing provided by him, AAK engineers found that the hydraulic system had a great impact on the valve spool and was greatly worn, so it was necessary to optimize the original structure of the hydraulic pilot operated cartridge relief valve. Chandler was a little dubious. After he learned that the shape and size of the hydraulic pilot operated cartridge relief valve would not need to be changed, he asked for AAK samples. After 35 days, AAK sent 20 hydraulic pilot operated cartridge relief valves. 3 weeks later, Chandler just told us that AAK hydraulic pilot operated cartridge relief valve could be installed in their system and the equipment operated normally, then there was no further information. 1 month later, I wrote an email to follow up, but there was no reply. Some time ago, we recommended a new model of hydraulic pilot operated cartridge relief valve equivalent to SUN hydraulics, and there was still no reply. Until CNY, he took the initiative to email us and placed a large order. Chandler said that after nearly 1 year of comparison and test, AAK hydraulic pilot operated cartridge relief valve has no problems in function, is stable, and its performance is satisfactory, and it is durable for 1 year without worry. AAK hydraulic pilot operated cartridge relief valve can quickly and stably overflow, can be adjusted remotely, and is durable, due to 3 special structures: 1. Inside the main valve spool of the cartridge relief valve, there is a spring connected with the inner wall of the valve body. In the upper space of the valve body, there is a pilot valve spool. The outer circle of the pilot valve spool is covered with a spring connected with the inner wall of the valve body. The two springs are inconspicuous, but effectively reduce the impact on the valve spool and improve the service life of the valve spool. 2. One side of the main valve spool is provided with a damping hole that can be connected with the inlet. The damping hole is connected with the position of the pilot valve spool, which can quickly and stably overflow. 3. A remote control port is set on the valve body, and the remote pressure regulation can be implemented by adjusting the hydraulic pressure at the upper end of the main valve spool. AAK hydraulic pilot operated cartridge relief valve, has stable function, satisfactory performance, and is durable for more than 1 year without worry.

AAK Hydraulic Valve Industry Scientific Research and Innovation
In the field of industrial products, China has made rapid progress in recent years, with many proud scientific research achievements and patented technologies. In the hydraulic valve industry, Chinese hydraulic valve manufacturers have also begun to export, in these two years. Each hydraulic valve manufacturer has its own engineers and its own R & D department. What is R & D? Many hydraulic valve manufacturers confuse the concepts of "scientific research" and "innovation". Generally speaking, "hydraulic valve scientific research" is to convert money into hydraulic valve knowledge, which is a department that spends money, while "hydraulic valve innovation" is to exchange knowledge for money and create wealth for enterprises. They cannot be confused. Some scientific research institutions have only completed "scientific research", but rarely completed "innovation". It is a pity that some hydraulic valve manufacturers in the world have invested a lot of money in research and development, but they are only immersed in theory and have not become innovative pioneers in the industry. AAK Hydraulic Valve, "scientific research" and "innovation" are two teams with different offices, rather than the same office and the same team as most hydraulic valve manufacturers. If scientific research achievements cannot be combined with practice to create value for all walks of life, these theoretical achievements are like empty promises. It is undeniable that at present, the gap between Chinese hydraulic valve manufacturers and international famous hydraulic valve manufacturers in terms of scientific research and technology needs generations of excellent hydraulic valve manufacturers to catch up, but AAK's most important thing is the innovation of hydraulic valves. During walking, it's easy to forget the original intention. I often reflect on where AAK Hydraulic Valve focuses? The value of a manufacturing enterprise is not measured by the number of orders or output, but depends on its contribution to the industry. Just like a person, his fame or status is that the society has given you more trust and responsibility to promote social progress. Whether in the hydraulic valve industry or in society, try to be a person with feelings, temperature and style. How can it be satisfactory, but I want to be worthy of my heart. Make a supreme wish, enjoy a lower blessing, choose a high place to stand, and walk to a wide place. Whether the manufacturing of hydraulic valves is difficult or not, AAK insists on traveling with innovation and dreams. Because we are lucky to catch up with the tide of development in the era of industrial products, appreciate the era and contribute to the industry. AAK Hydraulic Valve, with innovation and dreams, is willing to walk with you together. https://www.aakindustry.com/i , nfo-detail/hydraulic-valve-manufacturers-aak283 Contact:

AAK Hydraulic Cartridge Relief Valve Spool Accuracy within 1μm
Tunesi from Bulgaria, has been tortured by a hydraulic cartridge relief valve with 1μm accuracy spool for 3 months. At the beginning of this year, they developed a set of hydraulic manifold that requires the use of hydraulic cartridge relief valves, with high accuracy requirements, especially for valve spool that need to be controlled within 1μm. Tunesi chose an old hydraulic cartridge valve manufacturer in China to make samples. It took 3 months. Every time, among the 10 pcs of hydraulic cartridge relief valve testing samples, there were always several valve spools did not meet the standards. The original manufacturer gave up. The newly developed hydraulic manifold has not been successful due to poor procurement of hydraulic cartridge relief valves, and Tunesi is very annoyed. Tunesi found AAK and inquired via email,‘Can AAK control the spool accuracy of each hydraulic cartridge relief valve within 1μm?’For customers who send inquiry for the first time, whether the answer is yes or no, it is meaningless. I sent him a hydraulic cartridge pressure control valve that we customized for a Russian customer last year, with a focus on valve spool accuracy of within 1μm. Tunesi immediately sent the drawings and sample images of their hydraulic cartridge relief valve. After communication, it was learned that the original manufacturer cannot meet the spool accuracy of within 1μm. I told him that to guarantee the valve spool accuracy within 1μm, AAK has 3 steps: first, selecting high-precision equipment, second, programming and experienced technicians, one-on-one landing, and third, after processing, each valve spool needs to be inspected, screening out the valve spools exceeding the accuracy standard. After 45 days, AAK sent out 10 samples of the reprogrammed hydraulic cartridge relief valve. 2 weeks later, Tunesi informed us that their engineers had tested each spool of AAK hydraulic cartridge relief valve and they all met the standards. The hydraulic cartridge relief valve that the original manufacturer did not succeed for 3 months was finished successfully by AAK in half the time. Tunesi was very curious, and I reported to him that compared to the original manufacturer, the advantage of AAK should be in testing, because some of the hydraulic cartridge relief valves sent by the original manufacturer every time can meet the spool accuracy standard, but cannot be 100% qualified or some are unstable. AAK detected in this way: using the VX8000 series flash tester, with high- resolution optical lens, 20 million high pixel industrial camera, and autofocus. Firstly, place the precision machined valve spool on the internal platform of the instrument, set the accuracy requirements for the testing program, press the start button, and the testing instrument will start working. The lens will automatically align with the valve spool for projection. The lens can automatically locate, focus, measure, compare with the program, and then automatically determine whether the valve spool accuracy meets the standard. The entire process eliminates the need for manual labor and avoids human error. Each valve spool is tested to make sure an accuracy of within 1μm, it's not difficult. Most hydraulic cartridge valve manufacturers in China do not have this instrument, and for high-precision valve spools, they can only rely on precision machining, so the stability of valve spool accuracy cannot be guaranteed 100%. AAK hydraulic cartridge relief valve, spool accuracy within 1μm. Welcome to give it a try.

AAK Hydraulic Pressure Reducing Valve angle error of inner cone only 0.06°
Ilona is from a hydraulic equipment company in Turkey. At the beginning of last year, less than 3 months after joining the company, he needed to purchase a batch of hydraulic pressure reducing valves for their new hydraulic equipment. Ilona placed the order with an old supplier of hydraulic pressure reducing valves that has cooperated for 3 years. After 45 days, the equipment began to be installed and debugged, but the pressure supply of the equipment was unstable. The problem lies in the leakage of the hydraulic pressure reducing valves. The specific problem lies in the error between the angle of the cone in the valve sleeve and the requirements. The engineer asked Ilona to replace the hydraulic pressure reducing valves. The manufacturer of the hydraulic pressure reducing valves said that the error control was already the limit. Ilona contacted several other hydraulic cartridge valve manufacturers and didn't get a reply. He was very helpless. Ilona noticed AAK hydraulic valve online and left a message on AAK website: Can AAK produce the hydraulic pressure reducing valves with the angle error of ± 0.8 ° of the cone in the valve sleeve? At that time, I felt that it was a customer with high quality, so I became interested. Ilona also sent the technical parameter requirements and drawings of the hydraulic pressure reducing valve. Our technical team was aware of the challenge of this hydraulic pressure reducing valve. The error of the cone angle in the valve sleeve needs to be controlled within ± 0.8 °, and the maximum axial grinding tolerance of the corresponding sealing circle is 7.5μm. These two precision requirements are difficult for most manufacturers to achieve, but our engineers are confident. 50 days later, AAK shipped the trial order of 30 hydraulic pressure reducing valve. Two weeks later, Ilona emailed that AAK hydraulic pressure reducing valve was installed on their hydraulic equipment. The problem of abnormal pressure supply had been solved and the equipment operated well. Their engineers told Ilona that the measurement error of the inner cone angle of AAK hydraulic pressure reducing valve was only 0.06 °, which was 30% higher than the standard, and the measurement error of the axial dimension of the sealing circle reached 2μm. It is 3 times higher than the standard. Their engineers wanted to know how AAK achieved it? The reason why AAK hydraulic pressure reducing valves achieved what other hydraulic cartridge valve manufacturers can't, and the two error standards are increased by 30% and 3 times, is that AAK control the quality in 3 aspects: modeling, processing and detection, which most hydraulic cartridge valve manufacturers can't do. 1. Through the process analysis of the hydraulic pressure reducing valve, our engineers establish the manufacturing error model to control the change relationship between the internal cone angle error and the grinding amount, which is the core of doing a good job of error. 2. GILDEMEISTER turning milling compound machining center is adopted, which can compensate the errors caused by tool wear and other reasons during the machining process. At the same time, the double reading head c-axis position detection technology enables the positioning accuracy of c-axis to reach 5 angular seconds, so as to ensure the minimum error of the conical surface in the valve sleeve. 3. Then use the special 3 coordinate detection device to quickly measure the axial dimension of the sealing circle of the valve sleeve, so that the manufacturing error falls within the control range, and ensure that the inner cone angle and the axial dimension of the sealing circle of the hydraulic pressure reducing valve meet the standard. AAK hydraulic pressure reducing valves, modeling, processing, testing, 3 checks for accuracy error, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-reducing-valves- aak282 Contact:

China Hydraulic Valve Supplier of the World’s Top 500 Companies
A hydraulic valve giant came to talk business with you. Have you started to panic? If the other party places a large order of 1 million US dollars, which is a big business and also a big customer, what should be done to him, such as credit and price reduction? It seems to be not calm. From the perspective of quotation, I listed 3 DO principles and 3 DO NOT principles for myself and our sales department: 1. We do not pursue windfall profits, but take reasonable profits. 2. We do not do market common goods, but only benchmark SUN, HydraForce, HAWE, Honeywell and other first-line hydraulic valve brands. 3. We do not give rebates, but only provide hydraulic cartridge valves with the best cost performance In fact, many people don't understand the concept of cost performance. They think that cost performance means cheap. To understand it simply, we can use a formula: product unit price/product life=cost performance. For example, for a certain hydraulic valve, the price of Factory A is 100, and the service life of the hydraulic valve is 12 months; The price of AAK is 120, and the service life of the hydraulic valve is 24 months. The cost performance ratio of Factory A is 8.3; Similarly, the cost performance ratio of AAK is 5. This is the root cause of AAK hydraulic valve's insistence that "although the price is 20% higher, the service life is twice that of its peers". Of course, price negotiation is not only a mathematical calculation, but also requires pattern and thinking. Let me start with myself. 13 years ago, I produced hydraulic cartridge valves for trade and earned 100,000 US dollars. Of course I was happy. Later, after several years of accumulation, I made a total of 1 million US dollars, which is even more pleasant. If, after a few years or over 10 years of hard work, I have earned 10 million or 100 million yuan. Although I can't earn this money at present, think about it. As Jack Ma of Alibaba said, "Dreams must exist in case they come true". Let me take this order of magnitude as an example to analyze. When you make 100,000 yuan, what is the scope of your thinking if you buy something? What is the scope of your thinking after earning 1 million yuan? By analogy, with 100,000 yuan, the way of thinking must be different from that with 100 million yuan. When you have 100,000 yuan. would you like to buy a yacht? No. When it is 10 million or 100 million, the idea will be different. A basic truth is that when we talk about business and price, it is actually related to the cognitive pattern and is determined by the money we earn. 10 years ago, Honeywell, one of the world's top 500 companies, came to talk about hydraulic manifolds with me. They were satisfied with the first 2 trial orders, and were ready to increase the purchase from AAK hydraulic valve. The buyer specially emphasized that the delivery date should be accurate and the quality of the hydraulic valves should be good. I asked him how to understand the good quality of the hydraulic valves, and he said that just the current quality, same quality as the trial orders. The quality shall not fluctuate. It can not be the case that the first batch is good, but the third batch is not good. I don't require the quality to be best, but cannot fluctuate. At that time, I realized that the customers of industrial products wanted stable quality with fewer failures, rather than the best quality. For example, the hydraulic valve is of good quality at the beginning, but a few months later, some screw thread was adjusted, some seal ring was replaced, and the manual assembly was not in place sometimes. Although these are minor faults and can be solved as soon as possible, they are very troublesome. This refers to reliability, and they will not need to be reported for repair within a year or even longer. When talking about prices with key customers, what pattern and thinking height we should have. Take this buyer of Honeywell as an example. Because I had done business with him 3 times, I prepared some kickbacks for him privately according to the convention. He said no, really no. He said, I purchase more than 100 million yuan a year totally, and just more than 1 million yuan a year from you, why should I take rebates? When 1 million yuan of business is given to you from the Fortune 500, if you think this is a big customer, you should offer a low price, give rebates or something others, you think too much and think wrong. For the Fortune 500 or the global first-line brands, in fact, they are most concerned about your quality and service. As for the price, as long as it is not exceed their authority, it will be OK. If you used to do small business, it is difficult to do big business. Do not use the thinking of small boss to measure big customers. If a customer only purchases 2 million hydraulic valves a year, and 1 million are purchased from you, he will pay close attention to price negotiation. This has no comparability with the purchase of more than 100 million yuan a year totally but just 1 million yuan from you by the Global Top 500 companies. In his eyes, he didn't raise his eyebrows for 1 million yuan, and he didn't want to bargain with you, which is also the reason for doing business with a high-quality customer. In the process of our enterprise development, we will certainly encounter big customers to talk with you about business. Don't think of an elephant in your mind, because fixed ideas are flawed and difficult to eradicate. In general, if we often talk business with small customers and small bosses, our pattern and thinking will be limited. When encountering a big customer, we will not be confident and are afraid of big customer running away, and blindly compromised. In the end, the quality was not guaranteed, and the business with the customer died. Enterprises move forward in waves, from high to low. This is also a problem for small enterprises. For small boss, once business is good, the whole world seems to be mine. Once the business is poor, the end of the world is coming. He will be thinking hard about whether his price is too high and has more requirements for customers, so he starts to feel uneasy. Of course, this psychological quality also depends on whether you earn money. If you earn money, your psychological quality will be better. If you can't earn money, your psychological quality will be worse. Nothing can be insisted on without a sense of achievement. AAK hydraulic valve, adhering to the 3 DO principles and 3 DO NOT principles, originates from the support of the world's top 500 companies. https://www.aakindustry.com/info-detail/hy , draulic-cartridge-valves-416 Contact:
