Juan is the purchasing director of a Spanish hydraulic valve company in China. An old customer he served increases the hydraulic valve orders by more than 30% every year. Because of his good performance, the boss attaches great importance to him. Earlier this year, this old customer gave him an inquiry for a high-precision hydraulic check valve. The roughness of the installation surface of the hydraulic check valve should be below 0.8μm. He contacted several hydraulic valve manufacturers, they all said that the roughness of the installation surface of the hydraulic check valve can only be 0.9-1.0μm. After a few days, he still didn't reply to the inquiry of this old customer. He dared not refuse, but he was worried that the quality could not be achieved, which put him in a dilemma.
Juan contacted us through the introduction of other hydraulic valve manufacturers in Ningbo and directly asked if we can produce the hydraulic check valve with the roughness of the mounting surface below 0.8μm. He also truthfully told me that he had already contacted several hydraulic valve manufacturers, but they all can not guarantee it. He hoped that AAK hydraulic valve can give a surprise. Indeed, now 95% of the hydraulic valve manufacturers ignore the accurate grinding of the mounting surface of the hydraulic valve, resulting in the various roughness value of the conventional mounting surface of the hydraulic valve, some is 1.2μm, some is 1.0μm and there is also 0.8μm. The roughness value fluctuates and cannot be stabilized within a standard value range. As a result, the tightness is weakened during installation. Once it is not well controlled, the leakage of the product will increase, which will affect the normal operation of the whole hydraulic system. The roughness of mounting surface reaches 0.8μm is a critical value, which many hydraulic valve manufacturers lack in technology.
According to the drawings provided by Juan, we found several similar hydraulic check valve samples and provided our quotation. Juan sent the draft order. After communication, we learned that his customer was very satisfied with all the parameters and indicators of the hydraulic check valve samples we sent. If his target price can be accepted, the hydraulic check valve order can be confirmed. The price difference is not big, just a few percentage points. So I happily made a new customer of hydraulic check valve.
The roughness value of the mounting surface below 0.8μm has always been a hard index for the external leakage of AAK hydraulic valve. From the selection of the most suitable sealing ring to the roughness control of the mounting surface, grinding for many times and testing for each time to avoid any artificial leakage of the hydraulic check valve until there is no leakage on every AAK hydraulic check valve. The roughness of the mounting surface can be controlled at 0.8 μm below, it is basically difficult for domestic peers to achieve, while AAK hydraulic valve has been mass produced for more than 1 year.
3 months have passed since the large shipment of this hydraulic check valve, and a return order was issued for the same hydraulic check valve last week. Juan told me that since using AAK hydraulic check valve with the roughness of the mounting surface below 0.8μm, this old customer has sent more and more inquiries to him for the high-precision hydraulic valves, which has also driven the orders of other hydraulic valves. Now the order volume of hydraulic check valve in a quarter has been more than twice that of the same period. Now the boss pays more and more attention to him, and he is doing more and more vigorously.
AAK high precision hydraulic valve, guarantee accuracy below 0.8μm and no leakage, which makes most domestic peers despair. If you are looking for a manufacturer for high precision hydraulic cartridge valve, contact us to have a try.
Monroe is from Sweden and has been purchasing hydraulic threaded cartridge valves from Ningbo for 3 years. In January of this year, their customer wanted to place a repeat order for one of their hydraulic unit equipment,
