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 VNB series a 2 port process valve for a wide variety of fluids including air, water, oil, gas and vacuum. It is available with three types of body material: copper alloy, aluminum and stainless steel.

  • External pilot solenoid type
  • Flow rate ranges from Cv of 0.80 to 43
  • Orifice size: 7mm to 50mm
  • Port size: 1/8 to 2 Rc(PT)
  • Seal material: NBR
