Erdmann has been a purchaser of German HAWE company for 5 or 6 years and has been doing very well. Last month, the company had a special hydraulic threaded cartridge valve to purchase. Because it is to be used in the Arctic region, the corrosion resistance of hydraulic threaded cartridge valve needs to be very high. The boss asked him to identify the suppliers and approve the samples within 2 months. Erdmann felt that it could be completed within 20 days. He sent the drawings of hydraulic threaded cartridge valves to the original hydraulic valve manufacturers. Only 2 weeks later, he received samples of hydraulic threaded cartridge valves from one factory. The surface gloss of these samples of hydraulic threaded cartridge valves was quite good. The company tested them on the exploration drilling machine and delivered it quickly to the customer. 3 months later, the customer complained that the hydraulic threaded cartridge valve on the hydraulic pump was seriously corroded, some threads were stuck, the equipment could not be started, and the test run was unsuccessful. The boss thought that Erdmann was careless and ignored the use scene of the Arctic region. The boss again asked him to make new samples and do salt spray test inside the company. Actually, Erdmann emphasized that the hydraulic threaded cartridge valve is to be used in the Arctic region. The original supplier said that their hydraulic threaded cartridge valves have good gloss and corrosion resistance, and can be used in the Arctic region. Erdmann communicated with the original hydraulic threaded cartridge valve supplier again, and the reply was that most hydraulic valve manufacturers just adopt the zinc plating process, and he used the nickel plating process which is the highest level of corrosion resistance. Erdmann realized the difficulty of corrosion resistance in the Arctic regions. Erdmann emailed more than 20 hydraulic valve manufacturers who had been contacted before, emphasizing that the hydraulic threaded cartridge valve must be in the highly corrosive environment in the Arctic region, and the service life shall not be less than 9 months. Only 3 hydraulic valve manufacturers said they could have a try, but there was no response from other manufacturers. Erdmann was a little flustered. Erdmann saw AAK hydraulic valve on Google, who supplied to hydraulic pump company in Russia. He felt that AAK might give him a glimmer of hope. He emailed us to ask if we can produce hydraulic threaded cartridge valves to be used in Arctic regions. We directly replied that the components of the valve should be treated by special electroplating process in order to meet the condition in the Arctic regions. After 20 days, AAK sent samples according to his hydraulic threaded cartridge valve drawings. HAWE company conducted salt spray test on samples from all 4 manufacturers, with the corrosion condition twice that of Arctic regions. More than 2 months later, Erdmann informed us that AAK hydraulic threaded cartridge valve had no red rust after more than 1500 hours of salt spray test. At the same time, the company's engineers determined that AAK hydraulic threaded cartridge valve had no problem to be used in the Arctic regions for 1 year. While the samples from other manufacturers began to produce red rust in more than 120 hours, and there were white corrosion products on the coating surface. Erdmann hesitated to report to his boss because the quotation of AAK hydraulic threaded cartridge valve is 30% higher than that of other suppliers. The surface electroplating process of AAK hydraulic threaded cartridge valve is zinc nickel alloy coating, which has high requirements for steel heat treatment. It may be difficult to find a second factory in Ningbo who can go through both of these two processes smoothly. In addition, the process cost is more than 5 times higher, but the corrosion resistance is more than 10 times higher than the general zinc plating and nickel plating process. With these data, the communicated between Erdmann with the boss is very efficient. The boss mentioned that for all those valves with high standard and high working conditions, just to choose AAK hydraulic valves. AAK hydraulic threaded cartridge valve will not corrode in the Arctic regions even after being used for 1 year.

AAK hydraulic directional control valve, which has been used for 2 years, is free of rust and corrosion. It stands out from 3 hydraulic valve manufacturers. Joseph finally received a large order for 1000 hydraulic directional control valves from customer. Joseph is the purchasing manager of a hydraulic pump company in Italy. Two years ago, the company received a test order for a special chemical hydraulic pump, which needs a hydraulic direction control valve. The customer requires that after 2 years, if the hydraulic directional control valve is free of rust and corrosion, it will have the opportunity to obtain a large order. The boss asked Joseph to find a very professional hydraulic valve manufacturer. Joseph knew that relying only on the existing hydraulic valve suppliers is not enough to guarantee the quality. He checked with all the hydraulic valve manufacturers he had contacted before and the new ones searched online, and selected 16 hydraulic valve factories, including AAK Hydraulic Valve. He asked all hydraulic valve manufacturers to provide 2 samples of hydraulic directional control valves according to the drawing requirements of the customer for testing at their headquarters. According to the post analysis to the drawing of hydraulic directional control valve from Joseph, we found that there is no problem to meet the accuracy, sensitivity and durability of this hydraulic directional control valve, except that the finish of the outer surface of the hydraulic directional control valve must be free of abnormality, rust and corrosion after 2 years of use, which is too uncertain. We didn't receive email from Joseph until 15 days after we sent out the hydraulic directional control valve samples. According to their simulation test, only the hydraulic directional control valves from 3 factories can be approved to send samples to their customer. It would take 2 years for AAK to know if we can get the order of hydraulic directional control valve. At that time, we were very surprised that there were such strange customers. We almost forgot the test order of this hydraulic directional control valve 2 years ago. Last week, Joseph sent an email asking about the production time and new price of 1000 hydraulic directional control valves, and told us that the surface of the hydraulic directional control valves from other two hydraulic valve manufacturers began to have scratches, corrosion, fading and rust after more than a year of use, only the surface gloss of AAK hydraulic direction control valve does not change. In fact, when we sent out the hydraulic directional control valve samples, we were not 100% sure to meet this special requirement, because we used a new process to proofing. We know that the conventional nickel plating, chromium plating, zinc plating, blackening and other processes basically can not keep the same appearance after 2 years of use. We adopted electroless nickel plating. The principle of this process is to generate a coating on the metal surface by solution chemical reduction reaction, and the coating is amorphous. After treatment, the surface of the metal is smooth, corrosion-resistant and wear-resistant, and the coating film has few pores and uniform thickness. At the same time, the hardness of the heat treatment can reach HRC70. After confirming the order, Joseph privately reminded us several times that the surface finish treatment of large goods should be careful. His boss said that after this order was shipped smoothly, there would be more and more inquiries later, and his salary was raised by 2 levels. AAK hydraulic directional control valve is rust free and corrosion free. It is still the same as the new one after being used for 2 years.

Rex is a hydraulic valve wholesaler in Turkey. At the beginning of last year, their customer complained that the hydraulic cartridge relief valve, which has been used for less than 6 months, was stuck or worn, resulting in equipment shutdown. The original hydraulic cartridge relief valve manufacturer advised that under the equipment working condition of 450 bar, the hydraulic cartridge relief valve is likely to be abnormal, and the service life can be only guaranteed for 6-8 months. Rex realized that the hydraulic cartridge relief valve produced by this manufacturer was not reliable under high pressure. After checking with other hydraulic cartridge valve manufacturers, none of them was able to guarantee a service life of more than 1 year under 450 bar pressure. Rex was worried. Rex found AAK on Google. After staying at AAK website for more than 10 minutes, he found that AAK has hydraulic cartridge relief valve benchmarking HAWE, and is capable of high pressure resistant cartridge valves. He left us a message: Can the service life of AAK hydraulic cartridge relief valve be more than 1 year under 450bar working condition? After communication, it was learned that Rex was in a difficult position to purchase the hydraulic cartridge relief valve. I sent 6 cases of hydraulic cartridge valves with pressure resistance of 450bar for his reference. On the third day, Rex asked AAK to make samples per his drawing. He is open for the internal structure provided that the external dimensions were not changed, and the hydraulic cartridge relief valve had a service life of more than 1 year at 450bar. After 50 days, AAK sent 36 samples of hydraulic cartridge relief valve. 2 weeks after the samples were sent, Rex informed that AAK hydraulic cartridge relief valve worked normally on their equipment. Last week, Rex informed us via email that the equipment had been working for nearly 1 year without any customer complaint after being installed with AAK hydraulic cartridge relief valve. Their after-sales department is counting the number of the hydraulic cartridge relief valve that needs to be re-purchased. He asked me to wait for his further good news. This hydraulic cartridge relief valve can be safe under 450 bar high pressure for 1 year. In terms of material selection and material heat treatment, we follow the standards of HAWE, because AAK has engineer who has worked in HAWE for 13 years. At the same time, we have made 3 optimizations in the internal structure to challenge the high pressure. The optimized hydraulic cartridge relief valve has a buffering effect on the oil to avoid the impact of high pressure on the valve interior, reduce wear and avoid jamming, and has a 1 year of service life, which has been proved many times. 1. The hydraulic cartridge relief valve has an oil storage chamber and a buffer device inside the valve body, an adjusting nut outside the valve body, an adjusting screw cylinder inside, and a limit cavity, limit column, and a movable adjusting plate inside the adjusting screw cylinder. The screw connection between the adjusting screw barrel and the adjusting nut runs through the inside of the oil storage chamber. 2. The hydraulic cartridge relief valve has a built-in pressure regulating spring, one end is connected with a movable regulating plate, and the other end is connected with a piston. 3. The valve sleeve and threaded connection sleeve adopt the middle floating connection mode to avoid jamming. AAK hydraulic cartridge relief valve, the benchmark is HAWE, under 450 bar high pressure, it is safe for more than 1 year, welcome to try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak525

This week, we’d like to introduce a hydraulic solenoid cartridge valve equivalent to HydraForce SV12-34. It is a solenoid operated, two position, three way, direct acting spool valve. Last January in 2022, a customer in Russia found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. She sent us an inquiry for 10 pcs of HydraForce cartridge valve SV12-34, along with several other HydraForce standard parts. However, AAK did not have existing programming for SV12-34 at that time and did not quote. Instead, the customer placed trial order for the other models.   This January in 2023, the customer checked with us again if AAK is willing to develop SV12-34 as per their original samples. Although they can buy SV12-34 from other hydraulic cartridge valve manufacturers in China, they do not trust their quality. Because the quality of the other trial orders shipped by AAK last year was very satisfying, they want to develop SV12-34 with AAK. In March, the development was finished and delivered.   Last week, we were very happy to learn from the Russian customer that the E- SV12-34 Solenoid Cartridge Valve developed by AAK is running very smoothly, the quality is very stable. They are going to ask AAK to develop more and more new models.   AAK hydraulic solenoid cartridge valve E-SV12-34 two advantages: 1. Pressure Rating 207 bar (3000 psi), benchmarking HydraForce 2.
