Actuator	Double acting or Single acting, accessories are available
Advantages	1.No pressure loss, non-blocking, zero leakage, impact resistant 2.Full face-to-face integral elastomer molded flange 3.Manufactured to high standards 4.Superior service life 5.Sleeves available in a wide variety of elastomers 6.Custom sizes available 7.Bare body construction：The dynamic situation of the sleeve can be observed directly on the spot 8.With bias-ply, fabric-reinforced coating to protect the rubber sleeve, the sleeve is high abrasion resistant, corrosion resistant, tear resistant and fatigue resistant. 9.The sleeves are the only wetted part of the valve, eliminating the need for valve bodies made of expensive metal alloys. Because the sleeves are the only wetted part, they are the only replacement part needed in pinch valves, thus can save a lot of cost.

Applications

Industrial applications increasingly use pinch valves due to their advantages. Some of the industries using pinch valves include:

Food and beverage industries: Sanitary pinch valves have rubber sleeves made of nitrile, natural rubber, and EPDM, all of which are FDA-approved for contacting food. Also, a pinch valve cycles rapidly, which significantly increases packaging efficiency.

Pharmaceutical industry: Similar to the food industry, the pharmaceutical industry demands cleanliness, making sanitary pinch valves a good choice.

Chemical industry: The chemical industry has a broad range of applications. Pinch valves can accommodate many of these applications because of the variety of materials available for pinch valve sleeve production.

Cement industry: Natural rubber pinch valve sleeves are durable enough to withstand cement’s abrasion.

Bulk and solid handling industry: Pinch valves offer the abrasion resistance necessary to handle bulks and solids. The valves’ full-bore opening prevents solids from clogging the valve.

Ceramic industry: Pinch valves with reinforced rubber sleeves can handle the extreme abrasiveness of a ceramic flow.

Plastics industry: Pinch valves are suitable for moving plastic pellets and nibs, which may clog up other types of valves.

Wastewater industry: Pinch valves operate as pressure relief and shut-off valves in the wastewater industry.
