Valve feedback sensors boast high reliability
Reliable feedback of rising stem valve position is made easier with the Efector Valvis from IFM Electronic. This sensor has been specially designed to provide feedback on rising stem valves with strokes of up to 80mm. Using Efector Valvis means that complex mounting of several individual position sensors on the valve piston are no longer required. Moreover, uncomplicated programming by pushing a button replaces mechanical adjustment to the respective valve positions.
The Efector Valvis system operates on the inductive principle; the sensor signals up to three valve positions to the control system: valve open, valve closed and any position in-between - for example, seat lift. Three-colour LEDs indicate the switching output.
Rising stem valves differ, of course, so a range of adapters is available for Alfa Laval Suedmo, GEMU, Georg Fischer and other manufacturers' valves.
