Product Overview
The Rexroth Z2SRK 10-1-11/V (Material No. R900564520) is a pilot operated check valve from the proven Rexroth Z2S series, supplied in a sandwich (modular) plate design for direct mounting between a directional control valve and its subplate. The valve blocks flow in one direction without leakage and permits free return flow only when a pilot pressure signal is applied to the internal control piston, which mechanically lifts the seated poppet off its seat. This leak-free load holding function makes the Z2SRK 10-1-11/V a critical safety and positioning component in hydraulic circuits where actuators must remain locked in position against gravity or external forces, and where uncontrolled load drift or dropping must be prevented during pump shutdown or directional valve neutral. The size 10 (NG10 / CETOP 5) interface, spring-loaded poppet design, and external pilot oil supply configuration allow precise integration into modular manifold stacks and standard industrial power units.
