Fast 3 Way Valve

CF Fast 3 Way Valve (or Fast Commutator) contains two 3 way valves with a shared pilot conduit. As the pilot fluid moves a single membrane, the switching speed is maximised.

This product is specifically designed to be mount on FT positioner, up to 3 units if multiple functions are needed (quick open, quick close, lock in place). For fail freeze function, an integrated piezo solenoid valve is available as optional.


  • Compact dimensions
  • Without deformable diaphragm
  • SIL certified
  • Very fast pilot switching, even if piloted by low CV solenoid valve
