Collection: Pinch Valves
Pinch valves are a simple and effective solution for shut-off control of abrasive, corrosive and fibrous products. The pinch valves ensure an optimal shut-off, even when used with solids, such as granules, powders, pellets, chipping, sand, cement, gravel, textile fibers, carbon, fine glass fragments and slurries (liquids that contain solids). These valves provide completely free flow of the media and are clogging proof which makes them ideal for the listed media types. When selecting the pinch valve it is important to select the right body material, the sleeve material and connection ports.
The housing has a female thread on top where the air or hydraulic fluid supply can be mounted. Applying pressurized content through this connection port shuts off the flow of the media. They can be equipped with various connection ports which make them suitable for almost every piping system.
The sleeve provides dead space and leak-free operation of the valve and a media flow with minimum frictional resistance. Different sleeve materials make the valves suitable for various media and temperature ranges.
Important features to keep in mind are the maximum operating pressure which defines how much can a valve withstand and the control pressure that defines the pressure difference between control and controlled media. This pressure difference ensures safe and reliable control and shut-off of the media flow.
