to enable the following functions:

Under control descent of a load: load’s weight doesn’t carryit 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).


BODY: Zinc-plated steel
INTERNAL PARTS: Hardened and ground steel
SEALS: BUNA N Standard
TIGHTNESS: Minor Leakage

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


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.
