Electric pinch valves are devices used to control the flow of fluids, particularly in applications involving slurries, powders, and other viscous materials. Unlike traditional valves, which use mechanical components to open and close, pinch valves operate by pinching a flexible tube or sleeve. When the valve is activated, a mechanism compresses the tube, effectively stopping the flow of the fluid. When released, the tube returns to its original shape, allowing the flow to resume. This design is particularly beneficial for handling abrasive materials and providing a tight seal.
