R900347504 Z2S 6-1-6X/V Modular Pilot-Operated Check Valve
The Rexroth Z2S 6-1-6X/V (Part No. R900347504) is a compact, high-performance pilot-operated check valve designed in a sandwich plate layout for leak-free isolation of hydraulic actuators. Operating at Size 6 (ISO 4401-03 / CETOP 03), this valve installs between a directional control valve and a subplate to safely hold pressure and eliminate unwanted cylinder drift or load movement under pressure drops.
Equipped with high-grade FKM (Viton) seals for elevated operating temperatures and fluid compatibility, the Z2S 6-1-6X/V allows free flow in one direction while blocking reverse flow until opened via pilot pressure from the opposite line. Its stackable modular footprint eliminates complex external piping, ensuring a clean, space-saving, and leak-resistant assembly for industrial hydraulic systems.
