Z2S 06 Pilot Operated Check Valve
The Bosch Rexroth Z2S 06 is a high-performance, modular hydraulic valve designed to prevent fluid from flowing backward through an actuator line. It acts as an automatic lock, holding cylinders or motors perfectly still under heavy loads without any oil leakage.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Bosch Rexroth Z2S 06 (commonly written as Z2S 6) is a high-performance pilot-operated check valve in a sandwich plate design. It is primarily engineered for the vertical stacking of hydraulic systems, ensuring leakage-free blocking of one or two actuator ports during extended standstill periods.
