The email from Draper this morning made me in a good mood all day. I had two bowls of rice at noon. He said that 5 months have passed since AAK supplied the hydraulic needle valves in September last year, they have not received any complaints from users. His boss finally accepted his suggestion: "AAK is the preferred supplier for hydraulic needle valves, even if the price is 20% more expensive". Draper, whom we met in 2019, is a purchasing veteran of Doedijns company in the Netherlands. In 2019, he purchased 3 small batches of hydraulic needle valves from AAK in 3 times. He was very satisfied with the quality and service of AAK hydraulic valves, but in the recent two years of 2020 and 2021, he basically just placed orders for the very difficult and small quantity of hydraulic valves. Draper told the truth privately that he couldn't persuade the boss to place a big order with AAK. The problem is the price. Sometimes the price of AAK hydraulic valves is 20% higher than that of other manufacturers. Only the orders that are out of the capacity other hydraulic valve manufacturers will be placed with AAK. Last July, Draper sent us an email with the subject of "the production time of 1200 hydraulic needle valves". Because he had never sent an inquiry for such a big quantity of hydraulic needle valves, I thought that he sent the email to us by mistake. After communication, it was learned that he finally persuaded the boss to place big order with AAK even if the hydraulic needle valve is 20% more expensive, because they don't want to waste time on the after-sales for the hydraulic needle valves. In the past 2 years, customers have complained more and more about the hydraulic needle valves purchased by Draper. The complaints are basically about some small details of the hydraulic needle valves. For example, the hidden burr of the hydraulic needle valves in the hydraulic power system is not completely cleaned, which affects the matching accuracy and assembly of various parts in the system, as well as the tightness of the matching interface, resulting in internal leakage. Some hydraulic needle valves are complained by users after being used for even only 3 months. For many times, they needed to replace the hydraulic needle valves for users with new ones, which wasted too much of time due to after-sales and also interrupted the construction progress of users. The 1200 hydraulic needle valves purchased from AAK this time are the repeat order for their old customer. The customer said that they will not accept the repair of hydraulic power equipment within 6 months for any reason. Draper once again suggested the boss purchase the hydraulic needle valves from AAK, because in the past 3 years, there has never been any abnormal quality of any hydraulic valves purchased from AAK within 12 months. After comparing more than 20 hydraulic valve manufacturers, AAK is his most trusted hydraulic valve manufacturer. Perhaps his boss also knows that AAK hydraulic needle valve has never been complained. Although the pre-sales cost from AAK is 20% more, sometimes the after-sales cost of hydraulic needle valves purchased from other hydraulic valve manufacturers may exceed 20%. The boss finally agreed with Draper’s opinion. This time, the large order of hydraulic needle valves will be placed with AAK even if the price is 20% more expensive. Also, in the future, AAK will be the first choice for their hydraulic valves. The reason why Draper is not worried about the burr of AAK hydraulic needle valves is that he knows that AAK has the unique burr removal process that most other hydraulic valve manufacturers can't do. Firstly, the accurate position of the burr is determined, and the burr is removed by high-pressure solution jet. Then, there is one more step to re-check the residual burr that the other peers will not do. The burr part is rechecked by endoscope C50. If there are still residual burr, clean it again and recheck it again until it is completely eliminated. This is a detail awareness lacked by other hydraulic valve manufacturers, and also the reason why AAK can achieve 100% free of burrs. AAK endoscope equipment uses the number of CCD pixels and optical fiber conduction to automatically adjust the brightness during detection. It performs 360 degree detection on each hole in the valve body and clearly grabs each hidden burr, so as to ensure that each hydraulic needle valve is 100% free of burr residue. AAK hydraulic needle valve is unique in detail inspection. Welcome to have a small try! https://www.aakindustry.com/

Uistan comes from a hydraulic equipment manufacturing company in New Zealand, and has been in the company for 3 years. At the beginning of this year, an old customer of their company wanted to place the reorder for last customized hydraulic hoist, but required the stability to be increased by 10%. Their engineers required that: the hydraulic cylinder has a rod cavity, which is controlled by pressure; Rod less chamber, controlled by flow. Therefore, the hydraulic cartridge pressure control valve must have flow control and pressure control functions. Uistan contacted the original manufacturer to optimize the hydraulic cartridge pressure control valve, but the manufacturer was unable to do it. Uistan contacted more than 10 hydraulic cartridge valve manufacturers, but they were all not confident to guarantee that the hydraulic cartridge pressure control valve has both flow and pressure control functions. The engineer urged the progress several times, and Uistan was worried. While browsing Google, Uistean noticed AAK and left us a message: How to make the hydraulic cartridge pressure control valve have flow and pressure control functions at the same time? For this dual control hydraulic cartridge pressure control valve, there are not many hydraulic cartridge valve manufacturers that can produce it. After communication, we learned that his customer requested to improve the stability of the equipment, and they made a dual function request for the original hydraulic cartridge pressure control valve. In fact, AAK has customer cases for dual function hydraulic cartridge valves. Uistan was relieved when he learned. He hoped that AAK can help with the sample quickly. After 35 days, AAK sent 8 samples of hydraulic cartridge pressure control valves. 3 months later, Uistan informed by email that after installing AAK hydraulic cartridge pressure control valve, the customer was satisfied with the prototype, and the stability of the hydraulic hoist was at least 10% higher than before, and was willing to buy it again. The dual spool hydraulic cartridge pressure control valve designed by AAK allows two oil ports to adopt flow control and pressure control respectively, as follows: 1. Two connected fluid ports are respectively set on the two valve spools. The included angle between the center of the two ports and the connecting line between the ball center of the valve spool is 90 °. The two valve spools are set tangently. The caliber of the 4 fluid ports matches with the connecting port of the pipeline. 2. The lower ends of the two valve stems are connected with the valve spool. The valve body is provided with 4 pipeline connecting ports. The valve spool is arranged in the valve body. The upper end of the valve stem is connected with the valve stem control mechanism through the valve body. The center lines of the pipeline connecting ports are all located in the same plane. The contact parts between the two valve stems and the valve body are respectively provided with sealing rings. 3. The valve body bulges towards the middle of the valve body to form a diaphragm. The 4 fluid ports are connected through the diaphragm through-hole. Both sides of the diaphragm through-hole are attached with O-ring seals, which has good sealing performance and reduces the wear of the valve spool.

Sarabi from Israel, a hydraulic cartridge valve customer for military service. 2 weeks ago, he inquired about a hydraulic cartridge valve from AAK, for a military customer. I specifically investigated that company online. It is a very powerful hydraulic cartridge valve customer, and a type that I really like. After several rounds of communication, there was no any news for a week. The day before yesterday, Sarabi's feedback came: The price of AAK is a bit higher than other hydraulic cartridge valve manufacturers. The Israeli customer is very shrewd. They may have checked the price with other hydraulic cartridge valve manufacturers to compare prices in those days without any news. We often talk about quality comparison shopping, but in fact, it has now become a price comparison shopping. Firstly, I apologized to Sarabi for not properly introducing the hydraulic cartridge valve manufacturer AAK, which caused him to have no trust about AAK, no trust about the quality. Without trust, as a result, he had nothing to compare and could only compare prices. Subsequently, I introduced him AAK Partners: 1)Supply for HydraForce for 9 consecutive years and SUN for 5 consecutive years. 2)Honeywell, a Fortune 500 company, is also our client. 3)The listed company Skyjack Inc is also developing products at AAK. Selling points of hydraulic cartridge valve manufacturer AAK: 1)Manufacturing quality benchmarking with international first-line brands, top 3 in Ningbo. 2)AAK hydraulic cartridge valve has been used by Russian customers on Aircraft. 3)3-year warranty, no leakage, no vibration, no noise. I also invited him to read over 600 articles published on our website about AAK hydraulic cartridge valve customer cases, advantages, features, the unique characteristics different from the other hydraulic cartridge valve manufacturers in Ningbo China, the trust established in customers' minds on the internet. Only when hydraulic cartridge valve manufacturer AAK has become your default preferred supplier, perhaps you don't think AAK is too expensive. I told Sarabi not to compare AAK with other hydraulic cartridge valve manufacturers in Ningbo China, because AAK has no peers. Why does AAK has no peers? The purchase reasons, selling points, extensions, features, advantages, and benefits of AAK are already a fact. Then you think about it, how can there be a same hydraulic cartridge valve manufacturer like AAK in China? Sarabi ended this round of communication with a very interesting and refreshing exchange at the end. Today, Sarabi placed his PO and only requested a 2% discount. In half an hour, I sent back S/C. Today is a meaningful day for AAK, a hydraulic cartridge valve manufacturer in China, and for me. Taking this as a diary, I would like to see after 10 years, how many Israeli customers AAK, a hydraulic cartridge valve manufacturer in China, will have.

Jeff comes from Israel and has been purchasing hydraulic pressure control valves from China for less than 2 years. At the beginning of this year, a hydraulic pressure control valve with valve seat precision accuracy within 2μm has worried him for over 1 month. This hydraulic pressure control valve is used for hydraulic power units in the aviation industry. The hydraulic pressure control valve sample provided by the original manufacturer showed slight leakage after pressurization. Jeff's engineer found that the valve seat precision accuracy of the manufacturer was around 4μm. Jeff had to search for a new manufacturer of hydraulic pressure control valves. Jeff left a message on the AAK website: Can AAK control the valve seat precision accuracy of the hydraulic pressure control valve within 2μm? After communication, it was learned that he encountered difficulties in purchasing hydraulic pressure control valves from China. I sent out two models of AAK existing hydraulic pressure control valves the next day for him to test the valve seat precision accuracy. In less than 2 weeks, Jeff said that AAK's valve seat precision accuracy has been recognized by their engineers. He asked us to customize the hydraulic pressure control valve based on their drawings. After 35 days, AAK sent out 30 hydraulic pressure control valves. Yesterday, Jeff informed us via email that the sample was successful and the hydraulic power unit had been delivered to his client. If without any accidents, they will place a regular order for the hydraulic pressure control valves soon. In fact, the precision accuracy control of the valve seat is not difficult. The original hydraulic pressure control valve manufacturer Jeff found may not have the suitable equipment. The processing of this hydraulic pressure control valve is carried out by AAK using high-precision lathes of CITIZEN in Japan. Among more than 200 hydraulic valve manufacturers in Ningbo China, there are no more than 4 manufacturers who have this machine tool. Its advantage is that the component processing precision accuracy can reach IT8 to IT6 levels, and the tolerance can be guaranteed to be within 2μm, surface roughness Ra1.6-0.8μm. It is capable of achieving point control, with a spindle speed range of 300~10000r/min, its travel parameters can be controlled at 200mm/min. The most crucial thing is that the driving method of the back spindle adopts a built-in motor, which achieves the spindle speed range of 10000r/min and also improves the production efficiency of the hydraulic pressure control valve. AAK hydraulic pressure control valve, the valve seat precision accuracy within 2μm. For valve with high precision requirements, you can also give a try with us!

The local Israeli manufacturer was not willing to take risk to develop the hydraulic cartridge relief valve due to small size, and gave it up. After taking over, AAK made 3 improvements in the structure of the hydraulic cartridge relief valve, met the 3 requirements: 450bar high pressure resistance, 500L/min large flow, small pressure loss, and small volume. 3 months later, Vaughan sent an order for 600 hydraulic cartridge relief valves. Vaughan is from Israel, and they mainly focus on hydraulic equipment in the military market. At the beginning of last year, they customized a hydraulic power unit, which needs to have a pressure resistance of 450bar, the flow controlled by the hydraulic cartridge relief valve in the system exceeds 500L/min, with small pressure loss and small volume. He contacted a local hydraulic relief valve manufacturer to try the sample. The manufacturer reported that there was no problem with the functional requirements, but the size was too small and the risk was high, so he was unwilling to develop it. Vaughan contacted more than 10 hydraulic cartridge valve manufacturers, but it was fruitless after 1 week. Vaughan noticed AAK's article on high pressure and large flow hydraulic cartridge valves on B2B. He emailed me: can AAK try the hydraulic cartridge relief valve with high pressure resistance of 450 bar, flow over 500L/min, small pressure loss and small volume? My reply: It depends on how small the volume is. Vaughan sent the drawing of hydraulic cartridge relief valve. After getting the confirmation that AAK can optimize the internal structure of the hydraulic cartridge relief valve, he confirmed for us to make samples. After 50 days, AAK sent 12 hydraulic cartridge relief valve samples. 3 months later, Vaughan sent an order for 600 hydraulic cartridge relief valves. Their engineers were very satisfied with AAK hydraulic cartridge relief valves, which not only met the high pressure resistance of 450bar, large flow of 500L/min, small pressure loss, and small volume, but also completely met the requirements of the drawing, solving the space barrier of their power unit. AAK has made 3 improvements in the structure of the hydraulic cartridge relief valve: 1. The inner wall of the outer end of the hydraulic cartridge relief valve cage is provided with a boss to limit the valve spool in the valve cage. The valve spool, the valve cage and the valve cover form the first chamber. The first chamber is provided with a pressure regulating spring, one end of which is connected with the valve cover and the other end is connected with the valve spool body. 2. The right end of the valve cage is provided with a first oil port, and the circumference of the valve cage is provided with 2 rows of second oil ports. 3. The outer wall of the right end of the valve spool is provided with a groove, and the groove and the second oil port of the valve cage form a second chamber. For the hydraulic cartridge relief valve with such structure, when the oil enters from the first oil port and the oil pressure on both sides of the valve spool is not equal, the valve spool moves to the left, the 2 oil ports are connected, the valve port is opened for overflow, and the flow pressure loss in the valve is small. The valve cage is provided with a plurality of second oil ports to ensure large flow. AAK hydraulic cartridge relief valve, has small pressure loss and compact size, you can also try a small order! https://www.aakindustry.com/info-det , ail/relief-valves-aak452
