Product Overview
The Rexroth Z1S 16 P3-13 (Material No. R901362206) is a high-performance sandwich plate check valve engineered for modular hydraulic system integration. Manufactured by Bosch Rexroth, this component functions as a leak-free, direct-acting check valve designed to permit free flow in one direction while positively blocking reverse flow. As a sandwich plate design, it is mounted between a directional control valve and a subplate, enabling compact system architecture without additional piping. The valve is ideally suited for load-holding, isolation, and anti-reverse flow protection in demanding industrial hydraulic circuits.

Engineering Features & Advantages
- Precision Performance: Direct-acting poppet/seat design ensures fast response and reliable, leak-free shut-off in the reverse flow direction, protecting system circuits from unintended pressure reversals.
- Modular Sandwich Construction: Compact sandwich plate format allows direct stacking between directional valves and subplates, minimizing piping, leak points, and installation footprint.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components for long service life and stable performance.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification.
Typical Industrial Applications
This sandwich plate check valve is commonly deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic power units where reliable reverse-flow prevention and load holding are critical. It is also widely used in construction and marine hydraulic systems requiring compact modular valve assemblies.
