This week, weâ??d like to introduce a hydraulic pilot-to-close check valve equivalent to SUN COFA, a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. Last October, we received an inquiry from a new customer in the United States for SUN COFA Pilot-to-close check valve. This cartridge valve is not very commonly used, and there are only a few hydraulic cartridge valve manufacturers in Ningbo China that have this model in stock. Per customer, they placed the trial orders with 3 manufacturers, and will do durability testing at the same time. The one who has the best performance in the testing will be their preferred supplier. Last month, we received the good news from the customer that AAK samples passed the durability testing for 2 million times, and the price is in the middle among 3 manufacturers. But the manufacturer who has the lowest price did not pass the durability testing for 2 million times. They will choose AAK their preferred supplier for hydraulic screw-in cartridge valves. AAK hydraulic pilot-to-close check valve E-COFA two advantages: 1. The function and performance is equivalent to that of SUN COFA 2. Its service life is longer than of its domestic peers Technical parameters of AAK E-COFA hydraulic pilot-to-close check valve: Max. Operating Pressure: 350 bar (5000 psi) Flow: 40 gpm (160 L/min) Internal Leakage: 1 drops/min Cavity: T-2A AAK E-COFA hydraulic pilot-to-close check valve, benchmarking SUN COFA, its service life is 2 times that of its domestic peers. You are welcome to give it a try.

At 05:10 this morning, I was listening to music and browsing emails. Billy, who had no news in 9 months, sent an email. Without reading the email, I could guess that the hydraulic check valve developed by AAK for 3 months last year had a result. Opening Billy's e-mail and it is an annual order of 5,000 hydraulic check valves at one time, with about 500 hydraulic check valves delivered every month. Billy is from a hydraulic equipment company in the United States, he has purchased a small number of high-pressure resistant hydraulic check valves from AAK in the past. At the beginning of last year, his company received complaints from a customer that its high-power bulldozers were prone to weak starting of the hydraulic system after being used in less than half a year. The after-sales engineer found that the hydraulic check valves leaked and can not maintain the pressure and caused the problem. Billy contacted the original manufacturer of the hydraulic check valves, and manufacturer advised that the system pressure of the high-power bulldozer exceeded 450bar, and the opening and closing frequency was also high. When the hydraulic check valve was in the high-pressure state above 450bar, the valve spool was worn quickly, and the service life could only be guaranteed as 1 million times. Therefore, it was normal to replace the hydraulic check valves every half a year. If you want a hydraulic check valve with a service life of 2 million times, you can only purchase it from German HAWE. Billy has no choice but to make do with the hydraulic check valves of the original manufacturer first, but the after-sales cost every half a year is really unbearable. Maybe other manufacturers can offer hydraulic check valves with service life more than 1 million times. Billy began to contact other factories, including AAK. After receiving Billy's email, AAK engineers had reached a conclusion according to the hydraulic check valve drawings and bulldozer working parameters. In order to exceed the service life of 2 million times of the hydraulic check valves, we can only test new high-pressure resistant materials. We replied Billy at that time that according to the existing steel options of AAK, what your original manufacturer said was right, it can only guarantee the service life of 1 million times of the hydraulic check valves. However, we are confident to develop the one of 2 million times, because we have our own R & D experience in anti-high pressure. Billy replied directly that AAK would be given 3 months to sample the hydraulic check valves with pressure resistance above 450 bar. He also frankly informed that two other hydraulic check valve manufacturers were also making samples. If all manufacturers fail, they can only buy high-pressure hydraulic check valves from German HAWE. Three months later, AAK successfully sent 20 hydraulic check valve samples to Billy. Nine months later, the email came from Billy today.
Duden is from Lukas hydraulic equipment company in Germany. We have cooperated for more than 2 years on hydraulic check valves and hydraulic throttle valves. The order volume is small each time, but the parameter requirements are very high. AAK never despised it because of the small order quantity of the hydraulic check valves or hydraulic throttle valves. At the end of last year, their company developed a new hydraulic unit. Due to time constraints, Duden purchased hydraulic check valves and hydraulic throttle valves from local hydraulic valve manufacturers in Germany. The technicians found the original design defects after installing the integrated valve into the equipment. The position of the hydraulic throttle valve next to the hydraulic check valve is high, accounting for a little position of the motor, which makes it difficult to install the motor. Lukas engineers are a little depressed. If the position of the hydraulic throttle valve is changed, the whole oil circuit layout needs to be changed, but the power supply of the hydraulic system will be affected after changing the oil circuit. What is more troublesome is that there is not much time to redesign and proofing. The Engineers asked Duden to contact some local hydraulic valve manufacturers to check if the design size of the hydraulic throttle valve could be slightly adjusted so that the motor could be installed. Duden checked with several local hydraulic valve manufacturers, all of them were not willing to make samples because of small quantity of the hydraulic throttle valves. Duden tried to purchase small-size hydraulic throttle valves from China to solve the installation problem of the motor. Some Chinese hydraulic valve manufacturers said that they could make samples according to the requested size of their hydraulic throttle valves, but the time needed was more than 30 days. Duden couldn't accept this time and was more worried about the quality of hydraulic throttle valves from these factories. Duden sent an email to AAK asking if we could make several samples of hydraulic throttle valves in 5 days. In the past, the sample time gave by Duden was usually flexible with more than 2 weeks. After asking, I learned that their designers are facing embarrassment. It is also too tight for us to make several hydraulic throttle valves in only 5 days. I suggest Duden give us the overall layout of the integrated valve block. Maybe our engineer has a solution. According to the hydraulic schematic diagram provided by Duden and the specific use of the hydraulic integrated valve block, AAK engineers analyzed it step by step. Finally, it was found that if the hydraulic throttle valve and the hydraulic check valve were designed in parallel, the functions of the two valves were combined to form a hydraulic throttle check valve, which was installed at the position of the hydraulic check valve, and the installation hole of the hydraulic
Cuenca is a senior purchaser of AGRIA company in Spain. The boss is very satisfied with his purchasing work. Two years ago, AGRIA company developed a hydraulic equipment, and there were complaints after sales for more than half a year. The main problem was that the starting force of the hydraulic system would be insufficient, which was caused by the increase of internal leakage of the hydraulic check valves in the equipment. After Cuenca contacted the original hydraulic check valve manufacturer, the manufacturer said that some hydraulic check valves may have deviation during assembly, and he was willing to replace the hydraulic check valves with large leakage with new ones. Cuenca thought it was completely solved after replacement, but what surprised him was that less than a year after the new hydraulic check valve was replaced, the same problem occurred again. The boss was very disappointed with his purchase of hydraulic check valves this time. The manufacturer of the original hydraulic check valves still said that except for replacing the hydraulic check valves, there is no other way. Cuenca began to worry that if the same problem happened a third time, it would be too shameless. To be safe, he began to look for a new supplier of hydraulic check valves and began to test samples. At the same time, he also wanted to know why the hydraulic check valves produced by the original manufacturer leaked. In this way, Cuenca contacted AAK hydraulic valve. After several rounds of communication with Cuenca, we learned the story between him and the original manufacturer of hydraulic check valves, and suggested him to send us the hydraulic check valves with problem and provide us the drawings of hydraulic check valves at the same time. AAK engineer disassembled the hydraulic check valves of the original manufacturer and found that there were wear marks on the sealing line on the surface of the poppet valve. When the pressure oil reversely enters the hydraulic check valve, the cone cannot strictly seal the oil and cause leakage, and some oil flows out of the oil inlet. After receiving AAK's analysis, Cuenca asked us to make 4 samples of hydraulic check valves according to his drawings. Our engineers designed a new hydraulic check valve according to the service frequency and working conditions of the equipment, replacing the cone valve with the ball valve. The cone valve is prone to fatigue creep deformation and wear after working for a long time, resulting in a gap between the valve sleeve and the cone, resulting in leakage. The outer circle of the ball valve can contact the inner taper ring line, and the connecting hole can be closed to reduce the leakage caused by wear. Cuenca was surprised that AAK dared to take the initiative to modify the drawings of their hydraulic check valves, and expected to see the sample performance of AAK hydraulic check valves. Two months later, AAK sent samples of the newly designed hydraulic check valves.
In the Spring Festival, I received a confirmed price for a large quantity of hydraulic check valves from Stephen. The contact between Stephen and I is only 2-3 times in the whole last year. It was noted at the end of the email that he needs me to contact him as soon as possible to discuss this hydraulic check valve. Stephen comes from American CASE company. We met the year before last. After communication, it was learned that at the beginning of last year, a bulldozer of their company needed to use hydraulic check valve, the one that AAK had made samples at the beginning. Because the price of AAK hydraulic check valve was 20% higher than that of his original supplier, Stephen did not choose to purchase hydraulic check valve from AAK. Some time ago, the customer complained that the hydraulic pump was damaged due to the sudden increase of hydraulic system pressure. Stephen communicated with the original hydraulic check valve manufacturer and the manufacturer replaced the hydraulic check valve with a new one, but 3 months later, the same problem came again. The customer was very dissatisfied that this delayed the construction and needed the problem solved at one time. Stephen went back to AAK and asked about the price of the hydraulic check valve. He needed us to maintain the quotation offered last year. I asked Stephen why he went back to AAK to purchase the hydraulic check valve. He told that since the first complaint from the customer, their engineers retested the original hydraulic check valve samples. The hardness of AAK sample was the highest, and the material hardness of each part of the hydraulic check valve was no less than HRC65. I know why their hydraulic check valve went on strike in 3 months. When we made the sample, we knew that the working pressure was more than 450bar, which was a challenge for the hydraulic check valve. The material hardness of each part of the hydraulic check valve is required to reach more than HRC65. There may be no more than 5 hydraulic valve manufacturers that can reach this level in Ningbo. Stephen wondered why the material hardness of each part of AAK hydraulic check valve can be over HRC65? 1. Material selection is the core. AAK adopts 20CrNi2MoV high carburizing bearing steel imported from Germany for this hydraulic check valve. 2. Heat treatment is the key. Through secondary quenching + cryogenic treatment + low-temperature tempering process, it is cooled to 650 ~ 700 and put into the furnace. After cooling to 450 ~ 500 , it is discharged from the furnace. The micro hardness is 237 ~ 247 HV. 3. In the later stage, point-to-point testing is the key. SonoDur3, a Rockwell hardness tester imported from Germany, adopts the UCI hardness test method, and the test program is fast and mobile to carry out nondestructive testing on the hardness of each component of the hydraulic check valve efficiently and accurately.
