Product Overview
The Rexroth Z1S10TA05-2TB9-41/F (material number R901274760) is a direct-operated, spring-loaded check valve designed for leak-free load holding and reliable flow control in industrial hydraulic systems. As a modular sandwich plate valve, it mounts between a directional control valve and its subplate, allowing unidirectional flow while positively blocking reverse flow with minimal pressure drop. The valve is part of the Rexroth Z1S series, a widely specified family of modular check valves known for compact construction, fast closing response, and dependable sealing performance in high-pressure circuits.
Technical Specifications

Engineering Features & Advantages
- Precision Performance: Spring-loaded poppet closes rapidly against reverse flow, providing tight shut-off and dependable load holding with minimal internal leakage.
- Low Pressure Drop: Optimized flow passages within the NG10 sandwich body minimize pressure loss in the free-flow direction, supporting energy-efficient circuit operation.
- Modular Integration: Sandwich plate construction enables quick installation between existing directional valves and subplates without additional piping or manifold modification.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened sealing surfaces and FKM seals for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in interchangeability.
Typical Industrial Applications
This modular check valve is commonly deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and general construction and marine hydraulic systems. It is typically used for load holding, preventing reverse flow in actuator lines, isolating circuit branches, and protecting pumps and downstream components from pressure surges in high-pressure industrial power units.
