Product Overview
The Rexroth Z1S6T05-41/V (Material Number R901086058) is a high-precision sandwich plate check valve designed for modular hydraulic system integration. As part of the Rexroth Z1S series, this valve is engineered to prevent reverse flow within a hydraulic circuit while enabling unrestricted forward flow with minimal pressure drop. The sandwich plate design allows for direct mounting between a directional control valve and its subplate, eliminating the need for additional piping and reducing overall system footprint. With a nominal size of NG6 (CETOP 3 / ISO 4401-03), this valve is ideally suited for compact, high-density hydraulic power units and manifold assemblies where reliable flow control and leak-free operation are critical.
