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

The pilot valves of the refreshed VF1000/3000/5000 series have been changed.
Due to the reduction of apparent power, the allowable leakage voltage of the AC type is now 8% or less of the rated voltage (compared with 20% or less of the rated voltage for the old VF).
If leakage voltage exceeding 8% of the rated voltage remains in the circuit when the valve is turned OFF, the pilot valve

The pilot valves of the refreshed VP300/500/700 series have been changed.
Due to the reduction of apparent power, the allowable leakage voltage of the AC type is now 8% or less of the rated voltage (compared with 20% or less of the rated voltage for the old VP).
