REXROTH Z2S 10-1-34/ R900407394

Rexroth Z2S 10-1-34/ Pilot Operated Check Valve Description This is a Rexroth Z2S 10 pilot-operated check valve, designed as a sandwich plate module. It ensures leak-free closure in one direction and allows free-flow in the opposite. The valve can be opened via a pilot signal to allow return flow. It’s a fundamental component for load-holding, positioning, and safety circuits in industrial hydraulic systems. Its robust design ensures reliability and a long operational lifespan. Specifications Manufacturer: Rexroth Type: Z2S 10-1-34/ Material Number: R900407394 Component Series: 3X Size: 10 (NG10) Porting Pattern: According to ISO 4401-05-04-0-05 Maximum Operating Pressure: 315 bar (4568 PSI) Maximum Flow: 120 l/min Label Info MNR: R900407394 FD: 61727 Type: Z2S 10-1-34/ Serial: 124956601 Application This valve is typically used in hydraulic power units for machine tools, presses, plastic injection molding machines, and general industrial machinery where precise control and safety are critical. Country of Origin Made in Germany CO2 Impact Opting for this pre-owned valve saves approximately 6.0 kg of CO2 compared to manufacturing a new one. This is equivalent to the CO2 emissions of driving a car for 30 kilometers. Availability This item is a used, tested product in excellent working condition. Available for immediate dispatch.

FAQ What is the primary function of a pilot-operated check valve like the Z2S 10?Its main function is to block flow in one direction (like a standard check valve) but with the added ability to be ‘piloted’ open by a separate hydraulic pressure signal, allowing flow to return through the valve. This is essential for holding hydraulic actuators or cylinders in position under load without drift. Can this Z2S 10-1-34/ valve be used with different hydraulic fluids?Yes, this valve is typically compatible with standard mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids like synthetic esters or water glycols, it is crucial to verify the compatibility of the installed seals (typically NBR) with the specific fluid to prevent degradation. What does the ‘sandwich plate design’ mean for installation?The sandwich plate design means this valve is installed by stacking it between a subplate (or manifold block) and a main directional control valve. This modular approach simplifies circuit design, reduces pipework, and allows for compact and easy-to-maintain hydraulic systems.
