3-WAY Piston valve in Stainless Steel – Deviation or Mixing Function. The valve is provided with three entries that can be used as a deviation or mixing function, thus allowing to replace two off 2-way valves. In the Single Effect version, when the valve is in rest conditions (without compressed air power supply), the gate C of the valve is closed because of the strength of the spring. When the actuator piston is supplied by compressed air, the gate C of the valve is open, whilst gate B is closed.
In the Double Effect version, the valve opens and closes with compressed air.
