Germany Rexroth one-way throttle valve Z2FS22-8-3X/S2

Valves of type Z2FS are one-way flow control valves of stacked disc design. These valves are used to restrict flow in one or both actuator ports. Two one-way throttle valves arranged symmetrically to each other restrict flow in one direction (via an adjustable throttle spool) while allowing free return flow in the opposite direction. In the case of throttling in, the hydraulic oil is fed through channel A1 to actuator A2 through the throttling point (1). The throttle spool (2.1) is axially adjustable via the main shaft (3), allowing the throttle point (1) to be adjusted.
