R900407439 Z2S 10-1-3X/V Modular Pilot-Operated Check Valve
The Rexroth Z2S 10-1-3X/V (Part No. R900407439) is a high-performance, pilot-operated check valve in a sandwich plate design, engineered for leak-free isolation of hydraulic actuators. Operating in size 10 (ISO 4401-05), this valve is installed between a directional control valve and a subplate to safely hold working pressure and prevent unintended cylinder drift or load movement under pressure drops.
Featuring FKM (Viton) seals for elevated temperature and fluid compatibility, the Z2S 10-1-3X/V allows free flow in one direction while blocking reverse flow until opened via pilot pressure from the opposite service line. Its stackable modular footprint eliminates extra piping, ensuring a compact, leak-resistant manifold assembly for industrial hydraulic systems.
