USE AND OPERATION
This valve is used to adjust flow speed of actuators in one direction; flow is free in reverse one. As pressure compensation is not provided, flow adjustment depends on pressure and oil viscosity.
Body: Zinc-plated steel
Internal parts: Hardened and ground steel
Seals: Buna N standard
Tightness: By diameter combination. Minor leakage with closed valve.
Applications: Connect V to the pressure flow and C to the actuator to set. The flow is adjusted from C to V and free in the reverse direction. When used on actuator with double pilot check valve, VRF has to be mounted between the actuator and the double pilot check valve. Flow adjustment is made by rotating the coupling: by clockwise rotation flow increases and vice versa. Once the flow has been set, lock the nut in order to keep the desired settings, even case of vibrations.
