3 ways single pilot operated check valves, high pilot ratio

These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure is applied. Thanks to its high pilot ratio and very damped closure, it’s suitable to avoid instabilities in circuits with heavy loads.
WARNING: Please contact manufacturer prior to using this valve with open centre spool or electro- hydraulic cartridge valves.
