These valves are used to control the actuator movements and block it in both directions. In order to have the descent of a load under control and avoid the load’s weight being carried away the valve will prevent any cavitation of the actuator.
This valve is ideal when normal overcentre valves doesn’t work properly as it’s not sensitive toback pressure. They also allow the system pressure to move multiple actuators in series.
Flange ports enable direct mounting of the valve onto the actuator.
