Bosch Rexroth Z1S10P1-34 Valve Sandwich Module

Bosch Rexroth Z1S10P1-34 Valve Sandwich Module is a sandwich-plate, direct-operated check valve assembly in the Z1S family, designed to integrate a one-way flow control function into hydraulic manifolds in a compact footprint. Sized for a Z1S10 configuration, it embeds a check valve into a sandwich plate for inline blocking of reverse flow in hydraulic circuits. For size 10, the porting pattern follows ISO 4401-5, NFPA T3.5.1M R1, and ANSI B93.7 D 05, ensuring compatibility with standard mounting interfaces. Verified specifications include a maximum operating pressure of about 315 bar (approximately 4600 psi), selectable cracking pressures of 0.5, 3.0, or 5.0 bar, and a flow capacity up to 100 L/min, making it suitable for medium- to high-flow circuits. The module is documented under Bosch Rexroth catalog references for Z1S size 10 check valves, with part number 164676 representing this specific configuration. Typical applications include compact hydraulic assemblies where reliable backflow protection and a sandwich-plate form factor are required.
