Rexroth Z1S 6 P05-40/V SO90 Pilot Operated Check Valve
The Rexroth Z1S 6 P05-40/V SO90 is a high-quality pilot operated check valve featuring a sandwich plate design for modular hydraulic systems. As a size 6 (NG6) valve, it conforms to the ISO 4401 porting pattern, allowing for easy installation and stacking with other directional, pressure, or flow control valves. This model provides leakage-free blocking of the P port, ensuring that actuators remain locked in position even during extended periods of standstill. The valve allows free flow in one direction and can be opened against the closing direction via a pilot pressure signal. Engineered by Bosch Rexroth in Germany, this component is built for reliability and precision in demanding industrial applications. The inclusion of FKM seals makes it compatible with a wide range of hydraulic fluids and operating temperatures.
