Understanding the Pinch Valve Mechanism
Having the simplest valve design, pinch valves comprise of a flexible elastomer body that obstructs the flow of media through the pinching mechanism of the rubber sleeve, which is the main working element. The rubber sleeve is pinched closed either by the application of fluid pressure or mechanically in the body. It is squeezed at the valve’s mid-section, clamping or pinching its walls together to tightly close the flow path.
