Z2FS SERIES MODULAR CHECK CONTROL VALVE
The Z2FS type sandwich-type check valve** regulates the flow rate in the oil circuit by adjusting the cross-sectional area of the throttle orifice, achieving flow control. In the reverse direction, the oil flows directly back through the check valve. For sizes 6 and 10, different installation positions can be selected to achieve either inlet throttling or outlet throttling. For sizes 16 and 22, different models can be chosen to achieve inlet throttling or outlet throttling, and both oil lines of the working chamber can be connected simultaneously.
