SHR
The Atos SHR is a high-performance, modular hydraulic check valve designed for sandwich-plate stacking. It functions primarily as a leak-free blocking valve to hold hydraulic cylinders or loads securely in position. By mounting directly underneath a directional control valve, it eliminates external piping and prevents actuator drift caused by spool leakage.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
