Double throttle/check valve type Z2FS6…L4X

Valve type Z2FS 6 is a double throttle/check valve with sandwich plate structure.

It's used to control the flow by changing the throttling. In the opposite direction, fluid flow freely via check valve.
For meter-in control fluid passes from port A1 to port A2 via the throttling point (1), which is made up of the valve seat (2) and the throttling spool (3). The throttling spool (3) is axially adjustable via the adjustment screw (4).

Fluid flows from A2 to A 1, valve seat (2) is opened against spring (5) and valve acts as check valve. Depending on the installation position, the throttling effect may be arranged as a meter-in or a meter-out control.
