The quality of the valve spool can only be measured and compared from the 4 main aspects: the movement sensitivity, stability, no leakage and long service life of the spool in the valve body. The 6 processing procedures and 6 parameters of AAK valve spool also impressed Russian customers.

At present, some of the valve spools used by the hydraulic valve manufacturers are purchased outside from the valve spool factory, which is the common market goods well known in the hydraulic valve industry, with high output and low price. There are also hydraulic valve manufacturers that produce valve spools themselves, but the workshop only produces and tests according to the process sheet of the production department, and basically does not consider the type of hydraulic valve, hydraulic force on the valve spool, flow coefficient of the valve spool, pressure and flow characteristics, service scenarios of the hydraulic valve, and media. That is to use the same production standard to produce all different types of valve spools.

Boris from Russia is mainly responsible for purchasing high-end hydraulic valves, and some requirements are jokingly called curiosity by peers. Due to restriction of production process or lack of awareness of quality control, many hydraulic valve manufacturers dare not accept his orders. Just last month, our old customer, Erin, brought Boris to our company. I was surprised at the moment we met. Maybe he was really worried and went straight to the subject, there was an order for hydraulic flow valve that couldn't pass the inspection, and then took out 5 samples of hydraulic flow valve.

We conducted simulation tests according to the service scenarios, media and parameter requirements of the flow valve provided by him. The test results of the flow valve are not optimistic, the valve spool is stuck,
