These valves are suitable for shutting off, distributing and metering of powdery and grained bulk goods, for viscous, soiled and aggressive liquids, gases and mixtures. The cylindrical, elastic hose will be squeezed by compressed air or water pressure. Thus the pinch valve is closed. After release of the control pressure, the hose opens and returns in its original and circular shape.
