IFM Electronic’s new Efector valvis is designed to provide feedback of rising stem valve position with a stroke of up to 80mm. Using Efector valvis means that complex mounting of several individual position sensors on the valve piston is no longer required. Programming by pushing a button replaces mechanical adjustment. Operating on the inductive principle, Efector valvis signals up to three valve positions to the control system: valve open, valve closed and any position in between, for example, seat lift.
