How does pinch valve work ?

The pinch valve is composed of valve body, rubber sleeve, valve stem, upper and lower gate etc.

The pinch valve is turned in the forward direction, the large and small valve stems simultaneously drive the upper and lower gates, compress the pipe sleeves to close, and open when reversed.

In this way, the gate reciprocates up and down between the guide posts to complete the valve. Opening and closing work.

In addition, because the rubber tube sleeve bears the force, when switching, the operator only needs to feel a certain amount of resistance when turning the handwheel, and they have reached the opening and closing point. Do not try their best or use more people to assist, and disable other tools to open and close.
