Pinch valve

A pinch valve is a valve that opens, closes, and regulates by pinching or releasing an elastic hose, also known as a hose valve or pinch valve. Its core feature is that the medium only contacts the elastic hose and does not come into contact with metal components such as the valve body or stem, fundamentally eliminating corrosion and contamination issues. Inside the pinch valve is an elastic rubber or fluoroplastic hose. A manual, pneumatic, or electric mechanism drives a clamping device (such as clamping jaws or a pressure bar) to squeeze the hose from the outside, deforming it to close and shut off the medium. When released, the hose returns to its original shape due to its own elasticity, opening the passage. This design gives the valve a self-cleaning function – there are no dead corners when the hose closes, particles in the medium do not get stuck, and the flow path is smooth with minimal resistance. According to actuation method, they are divided into manual pinch valves, pneumatic pinch valves, and electric pinch valves. Pinch valves have a simple structure, reliable sealing, wear and corrosion resistance, and low maintenance costs (only the hose needs replacement). Hose materials can be selected from natural rubber, EPDM, NBR, PTFE, etc., to suit different media.
