Double Overcentre Valve

Use and operation:
These valves are used to control actuator’s movement and block in both directions in order to enable the following
functions:
1) Under control descent of a load: load’s weight doesn’t carry it away, as the valve prevents any cavitation of the actuator;
2) Limited maximum pressure in case of shocks created by loads, overloads or sudden manoeuvrings (load control with opened centre distributor).
Applications:
Connect V1 and V2 to the pressure flow, C1 and C2 to the actuator to be controlled. In-line mounting.
