Double Overcentre Valve

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:

Under control descent of a load: load’s weight doesn’t carry it away, as the valve prevents
any cavitations of the actuator;

Limited maximum pressure in case of shocks created by loads, overloads or sudden manoeuvrings (load control with opened centre distributor).

MATERIALS AND FEATURES:

Body: Zinc-plated steel
Internal Parts: Hardened and ground steel
Seals: BUNA N Standard
Tightness: Minor Leakage
Standard Setting: 320 Bar

Valve setting must be at least 1.3 times more than load pressure in order to enable the valve to close
even when undergone to the maximum load pressure.

APPLICATIONS:

Connect V1 and V2 to the pressure flow, C1 and C2 to the actuator to be controlled. In-line mounting.
