Bosch Rexroth AG Z1S 10 P1-33 Hydraulic Valve

Bosch Rexroth AG Z1S 10 P1-33 Hydraulic Valve is a sandwich-plate check valve in the Z1S family, a direct-acting device that blocks reverse flow in hydraulic circuits when installed in modular manifolds. This variant belongs to the Z1S10 family and is designed for use inside sandwich plates, offering a compact, cartridge-like form factor that integrates with ISO 4401 interface patterns; specific Z1S10 configurations such as Z1S10P05-1-4X/F show porting aligned to ISO 4401-05-04-0-05 and ISO 4401-05-05-0-05, ensuring compatibility with standard sandwich-plate stacks. In certain Z1S10 configurations a measuring port P is provided (P connection, typically G1/4 on the B-side channel), which supports monitoring and sample-point access in hydraulic circuits. The P1-33 designation identifies a particular variant within the Z1S10 range, used to protect pumps and actuators by preventing backflow in the line, and is commonly employed in compact hydraulic manifolds where space is at a premium. This valve type is compatible with Rexroth sandwich-plate systems and the broader Z1S check-valve family, and it supports standard valve-stack configurations that allow easy integration into multi-valve manifolds.
