Z2FS Throttle Check Valves

The Bosch Rexroth Z2FS Throttle Check Valves are throttle check valves designed as sandwich plate valves for use in hydraulic systems. They contain two integrated flow control orifices which work in parallel with a check valve. The valve works by allowing flow to be throttled in one direction (via the adjustable orifice) while simultaneously allowing free, unrestricted flow in the opposite direction (via the check valve). The primary function is to provide an adjustable restriction to the main or pilot flow of two actuator ports (A and B). This allows for the speed adjustment of hydraulic actuators by controlling the supply or discharge flow, and they operate with a maximum pressure up to 315 bar.
