The ISV valve is fitted between the vacuum generator and the suction cup. If, during vacuum generation, a suction cup is uncovered, or only partly covered, the ISV automatically stops the influx of air. When the suction cup fits tightly against the surface, a vacuum is regenerated. Removal of the object from the suction cup causes the ISV valve to close immediately.
Temperature range –10 … +60 °C. Operating pressure –0.95 … 0 bar.
