HBS pilot operated |check valves
Pilot operated check valves are normally used to allow free flow in one direction and to stop the fluid in the opposite one, unless a pilot pressure (Ppil) is applied by the other line of the circuit.
They can be used to ensure the static lock of a load, not for dynamic control or for lowering control.
If used in combination with restrictor valves, these ones should be preferably fitted between the actuator and the pilot operated check valve, not between valve and spool valve, so that the back pressure generated by the restrictor operates against the pilot pressure applied to the valve.
