Product Detail
Function and configuration
Valve type Z2FS is a double throttle/check valve with sandwich plate structure.
It is used to control the flow by changing the throttling. In the opposite direction, fluid flows freely through the check valve. For Z2FS10, depending on the installation position, the throttling effect may be arranged as a meter-in or a meter-out control. While for Z2FS16 and 22, depending on the model (S or S2) throttling may take place in either meter-in or meter-out, and at the same time the two operating oil chambers are connected.
