Product Overview
The Rexroth Z1S6P05-41/V (Material No. R901086051) is a direct-operated sandwich plate check valve designed for modular hydraulic system integration. Manufactured by Bosch Rexroth, this valve is engineered to block flow in one direction and allow free flow in the opposite direction, functioning as a reliable anti-return element within stacked valve assemblies. The Z1S6P05-41/V is a size 6 (NG6 / CETOP 3) sandwich plate component, designed to be mounted between a directional control valve and its subplate, enabling compact system design without additional piping. The “P” designation indicates the check valve is positioned in the P (pressure) port line, providing controlled flow directionality for the main pressure supply. With a cracking pressure of approximately 0.5 bar (05 code), this valve ensures low-resistance free flow while delivering positive sealing in the blocked direction. The Z1S6P05-41/V is a critical component in modular hydraulic circuits where backflow prevention, load holding, or directional isolation is required within a space-efficient manifold stack configuration.
