The pinch valve is particularly suited for applications of slurries or liquids with large amounts of suspended solids. It seals by means of one or more flexible elements, such as a rubber tube, that can be pinched to shut off flow.
YASH” make Pinch Valves offer a cost-effective solution to flow control problems. The secret is in the rubber sleeve - the valve's only wetted part. Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve. A rubber sleeve also known as rubber muff or tube is protected under a cast iron or aluminum body. The inside of this rubber sleeve has no crevices or indentations to allow slurry compound to collect and dry into hard, sharp material.
Pinch valves resist clogging and are best suited for tough applications which clog in the pipeline. Pinch valves being glandless and seatless with smooth interior construction lessen the chances of clogging considerably. Pinch valves can be operated by hand wheels, pneumatic actuators, hydraulic actuators or electrical actuators.
Aluminum Body / Cast Iron, Pinch valves having Rubber Sleeves are extra heavy with full covering flanges preventing corrosion on body and four reinforced pulling lugs for positive operation. The sleeve is internally completely reinforced.
