An electric pinch valve operates on a relatively simple yet highly effective principle： it uses an electric actuator to control the opening and closing of a soft, flexible tube (often made of rubber or elastomeric material). The tube is compressed by mechanical pinchers, which results in the restriction or complete shutoff of fluid flow. When the pinch valve is activated, the actuator releases the pinchers, allowing the tube to return to its original state, thereby permitting fluid flow.

    This design offers a number of advantages, especially for applications where fluid containment is crucial, such as handling aggressive, abrasive, or particulate-laden fluids.
