The VN series is a combination of process valves that can be operated with pressure differential zero and comes with many variations. The VNA series is used for controlling pneumatic systems or air-hydro circuits. The VNB series controls various fluids. VNC is used for controlling the cutting oils and coolants used in machine tools. VNH is for controlling high pressure cutting oils and coolants
