These pilot operated check valves operate as standard check (non-return) valves in one direction, but can also be opened by a remote pilot pressure signal to permit reverse flow.
pressure signal is applied to the valve’s pilot port. The graphical symbol for these valves is shown below. Pilot operated valves have very low internal leakage and are typically used to lock a cylinder in place until the main directional valve shifts. Pilot Operated In Out Pilot Note: Vickers also has a range of SAE flange mounted check ...
These pilot operated check valves operate as a direct check valve but can also be opened by pilot pressure, on the control piston, to permit free reverse flow. The amount of pilot pressure required to open the valve is stated as a ratio of the pressure above the check to the pilot pressure.
