Working status of pinch valve
Fully-open: the full-bore elastic valve sleeve of pinch valve without any gaps & dead spots.
Center closed: closed on the center line of the valve body, which avoids turbulence and abrasion, as a result, the valve sleeve becomes a smooth and enclosed venturi with self-cleaning during every operation.
Fully-closed: it ensures the pinch valve is with no leakage of two ways when shut off, and the safe design of inner valve sleeve requires no maintenance of sealing elements.
