Rexroth Z2FS22-8-31/S Hydraulic Pilot-Operated Check Valve (Sandwich Plate)
The Bosch Rexroth Z2FS22-8-31/S is a high-performance, pilot-operated check valve designed for vertical stacking assemblies in hydraulic systems. As a sandwich plate valve, it is mounted between a directional valve and a subplate, providing a compact and efficient solution. This valve’s primary function is to block flow in one direction while allowing free flow in the opposite direction. The integrated pilot control allows the check valve to be opened hydraulically, enabling the return flow of an actuator even under pressure. Engineered for reliability and precision, the Z2FS22 is ideal for applications requiring secure load-holding, such as in presses, machine tools, and industrial power units.
