Rexroth Z2S 10-1-34/V SO150 Pilot-Operated Check Valve
Rexroth Z2S 10-1-34/V SO150 Pilot-Operated Check Valve
The Bosch Rexroth Z2S 10 is a pilot-operated, double check valve sandwich plate designed to leak-proof lock hydraulic actuators. It is installed in a modular valve stack (sandwich design) and ensures secure load holding, even during long standstill periods or in case of pressure loss.
This valve is widely used in industrial, marine, offshore, and safety-critical hydraulic systems.
Identification & Part Details
• Manufacturer: Bosch Rexroth
• Product Type: Pilot-Operated Check Valve (Sandwich Plate)
• Series: Z2S
• Model Code: Z2S 10-1-34/V SO150
• Material Number (MNR): R901142833
• Nominal Size: 10 (NG10 / CETOP 5)
• Mounting Standard: ISO 4401-05-04-0-05

• Seal Material: V = FKM (Viton)
• Execution: Special Order (SO150)
Functional Description
The Z2S 10 is a double pilot-operated check valve, meaning both actuator ports (A and B) are securely blocked when no pilot pressure is present.
Operating Principle
• Free flow:
• A1 ? A2
• B1 ? B2
• Blocked flow:
• Reverse direction is blocked leak-free
• Pilot release:
• Pressure on port B pilots port A open
• Pressure on port A pilots port B open
This allows controlled movement of cylinders or motors only when pilot pressure is applied, preventing unintended motion.
Cracking Pressure
• Code “1” indicates standard cracking pressure
• Typically approx. 1.5 bar
• Ensures reliable sealing with minimal pilot pressure
SO150 – Special Execution
The SO150 designation indicates a factory-defined special version, commonly including:
• Enhanced sealing geometry
• Optimized valve seat for near zero leakage
• Tighter tolerances for safety-critical applications
• Used where absolute load holding reliability is required
Technical Characteristics (Z2S 10 Series – Reference)
• Max operating pressure: up to 315 bar
• Nominal flow: up to 80–100 L/min
