Use and Operation
This valve is used to adjust flow speed of actuators in one direction; flow is free in the reverse one. As pressure compensation is not provided, flow adjustment depends on pressure and oil viscosity.
Materials and Features
- Body: zinc-plated steel
- Internal Parts: hardened and ground steel
- Seals: BUNA N standard
- Poppet Type: by diameter combination. Minor leakage with closed valve
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 in case of vibrations.
