Product Overview
The Rexroth Z1S10A05-2-41/F (Material No. R901274762) is a direct-operated, spring-loaded check valve designed for leak-free load holding and flow direction control in industrial hydraulic systems. As part of the Rexroth Z1S series modular valve family, this unit is engineered for sandwich plate mounting (modular connection) per ISO 4401 / DIN 24340 standards, allowing it to be stacked directly beneath directional control valves without additional piping. The valve permits free flow in one direction while positively blocking reverse flow, providing reliable isolation, load holding, and protection against pressure surges in demanding hydraulic circuits.
