The high-pressure throttle hydraulic valve produced by AAK, the service life can be longer than 90% more of its peers, the key is that we have our own quenching and tempering heat treatment process, through the quenching with different tempering temperature, can raise the strength and toughness of hydraulic valve, as well as the fatigue strength greatly, to avoid deformation and abrasion happened in the process of hydraulic valve being used in the long-term. Currently, less than 10% of the industry can match the service life of AAK hydraulic valves.

In order to save costs, 70% of manufacturers do not do any heat treatment to the hydraulic parts materials, some of them do heat treatment, but outside of the factory, and 20% of the factories do heat treatment at a different place each time, due to these reasons, the quality can not be guaranteed, let alone the stability. Due to the existence of these common problems in the industry, after being used for a period of time, the hydraulic valve will expose lots of problems, such as deformation, abrasion and so on. Once the deformation of the hydraulic valve, the valve blocking will be more serious, and the abrasion will lead to increased leakage, which greatly shorten the service life of the hydraulic valve.

Last month, Jone, the purchasing director of the American customer in China, came to me and complained during the chat that since 2019, for unknown reason, his customers have been complaining one after another, and the problems are surprisingly consistent, the hydraulic valve has been deformed and worn out quickly in less than three months after being used.
