Single Overcentre Valves
Single Over centre Valves USE AND OPERATION:
These valves are used to control actuator's movement and block in one direction 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 to the free flow side of the actuator and C2 to the
actuator's side you want the flow to be blocked. In-line mounting.
ON REQUEST:

Pilot ratio 1:8 (specify CODE/RP18)
