PRESSURE COMPENSATION VALVE

摘要

A pressure compensation valve comprises a valve body, a valve sleeve fixedly mounted on the valve body, and a spool disposed in a valve hole of the valve body and capable of moving. The pressure compensation valve can change the pressure compensation characteristic, that is, the pressure compensation valve can change the difficult degree of the pressurized oil liquid flowing by changing an effective pressure acting surface of the pressure compensation valve The structure is simple, requires low cost, and increases the utilization rate of a product.
