The roughness of the mounting surface below 0.8μm has always been the mandatory quota of AAK HYDRAULIC VALVE to against leakage. By controlling the roughness of the seal ring and the mounting surface, and adjusting the parameters, the mounting surface is grinded for many times to ensure that leakage is avoided until every AAK hydraulic valve is not likely to leak. The roughness of the mounting surface can be controlled below 0.8μm, which is difficult for domestic peers to achieve.
Juan is the purchasing director of a Spanish hydraulic valve company in China market. One of his regular customers increases the orders by more than 30% every year. Some time ago, the old customer gave him an order with high precision requirements, and the roughness of the mounting surface of the hydraulic valve should be less than 0.8μm. According to his current understanding, the roughness of installation surface in China hydraulic valve manufacturers is generally between 0.9-1.0 μm, which is difficult to meet the requirements of the customer. He did not dare to refuse the order from this old customer, but also worried about the quality not meeting the requirements, so he was in a dilemma.
Juan sent this request to all his hydraulic valve manufacturers, but no manufacturer could guarantee this accuracy. At the moment of hesitation, Juan contacted us through the introduction of a factory, and expressed his concerns and the customer's requirements for the product. I also explained to him that 95% of domestic hydraulic valve manufacturers often neglect the accurate grinding of the mounting surface of hydraulic valves, resulting in rough surface of products produced, the roughness values of mounting surface are usually 1.2μm, 1.0μm, or 0.9μm etc. The control range fluctuates and cannot be stabilized in a standard range, which leads to the weakening of sealing during the installation process. Once the roughness is not well controlled, the hydraulic valve leakage will increase, and then affect the normal operation of the whole hydraulic system. It is a critical value for the roughness of the mounting surface to reach 0.8μm, which is also lacking in the technology of many hydraulic valve manufacturers.
Juan bought 5 samples from our company AAK HYDRAULIC VALVE and went back to do parameter testing. 15 days later, Juan sent his order to us. After repeated confirmation, we were advised that his customer was very satisfied with our product parameters. Before placing the order, the customer repeatedly stressed that the production should strictly follow the standard of the samples and designated our factory to produce the order for him.
It's been 2 months since we delivered the goods to Juan. Last week, he sent AAK a repeat order for $80,000, and told me that since the use of AAK hydraulic valve with surface roughness less than 0.8μm, this old customer has sent him more and more inquiries for the high-precision hydraulic valves, which has also led to the increase of orders for other hydraulic valves. Now the order volume in a quarter is more than twice that in the same period. Now the boss is paying more and more attention to him, and he is working harder and harder.
AAK hydraulic valve guarantees the high precision accuracy of 0.8μm and no leakage, which makes the domestic peers despair.
This week, we’d like to introduce a hydraulic cartridge valve equivalent to HydraForce PRES50-30. It is a screw in, cartridge style, direct-acting, spool-type, hydraulic pressure reducing/relieving valve
Yesterday, a new Indian customer visited Chinese hydraulic manifold manufacturer AAK. They were previously hydraulic manifold manufacturers in India and have been purchasing from Chinese hydraulic manifold manufacturers in recent years.
