{wiki=Pinch_valve}
A pinch valve is a type of valve used to control the flow of fluids through a pipe or duct. The operation of a pinch valve relies on a flexible tube or sleeve, typically made of rubber or another elastomeric material, which is pinched to regulate the flow. When the valve is actuated, the sleeve is pinched closed, restricting or stopping the flow of the fluid. When the pinch is released, the sleeve returns to its original state, allowing the fluid to flow freely again.
