Flow Control Valves

Thanks to NVD (STBF) & NVS (STUF) restrictors it is possible to adjust the oil flow passing through and control the speed of a hydraulic cylinder or motor.

The NVD (STBF) adjustment is bidirectional.

The NVS (STUF) adjustment is one direction, on the opposite side the flow is free.

The valves do not have an integrated hydraulic compensator and the set flow is effected by the pressure drops across the valve. The valves can be easily installed inline inside the hydraulic circuit through the two threaded ports.

The external body is made by steel and it is protected from oxidation by zinc plating treatment. The inner components are made of steel, hardened and ground where necessary. The knobs are made of Plastic.
