JIA NAI's Clamping Stirrup Air Operated Pinch Valves with a food-safe natural rubber sleeve for shut-off control applications with abrasive, corrosive, or fibrous media. A flexible elastomer sleeve is compressed by increasing the pressure in the pinch valve body. These create a lip-shaped closing pattern, powders or other medium is squeezed by the air pressure, can not move, or totally cut off to shut off. The continuous air pressure ensures the elastomer sleeve closes tightly.
The aluminum alloy air operated pinch valve from the VA series are designed for shut-off control applications with abrasive, corrosive, and fibrous media. The series includes pinch valves with female threaded ports, sizes ranging from 3/8 to 4 inches. The maximum operating pressure is at 6 bar (87 psi) and the maximum control pressure is 2 bar (29 psi) higher than the media pressure. These China Clamping Stirrup Pinch Valves can be equipped with either natural rubber food-safe sleeve, natural rubber abrasion resistant sleeve, or EPDM sleeve. These 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).
Valve body, casing rubber, bonnet, etc.
When the pneumatic system is closed, the space between the casing and the body is connected to the air, and the casing is under the pressure of the liquid, making it in an outward tension state. Because there is a reinforcing cloth inside the casing to maintain pressure balance, the length and diameter of the casing will not be changed by the liquid pressure. When the medium enters the space between the sleeve and the body, the sleeve will cut off the liquid under moderate pressure.
● Series 273 Pinch Valve is designed for high-purity fluid control in biotech applications
● Hermetic separation of the control mechanism and the fluid within the tubing prevents contamination, assuring maximum purity of liquids

● Available in a large range of body sizes to accommodate a wide variety of tubing sizes
● Typical applications include: Tangential Flow Filtration, Chromatography Skids, and Single-Use Bioreactors
● Available in Anodized Aluminum and Stainless Steel
A. We can install valves on any part of the pipeline without restricting the flow of the medium
B. The maintenance cost is very low, only need to replace the rubber of the casing according to the conditions of use.
Slurry, ore slurry, abrasive, wet and dry dust, solid-liquid, granular fertilizer, etc. Especially for mineral plants, chemical plants, power plants, sewage treatment plants, etc.
In the traditional industry and food industry, some abrasive solid or liquid products containing particles, powders, fibers, and slurry are often transported through pipelines. A pneumatic pinch valve is the best choice.The VF15 air operated pinch valve is a valve with excellent wear resistance and Read More »
When the control gas is not input in the pneumatic pinch valve, the cavity between the rubber sleeve and the valve body is in communication with the atmosphere, and the rubber sleeve is in an outward tension state under fluid pressure. Since there are reinforced plies arranged at a certain angle in Read More »
The pneumatic pinch valve series products have no sealing points and will not leak. They are resistant to particle corrosion and will not be blocked when transporting liquids containing fibers. Its performance is comparable to imported products, and it has the advantages of a short supply period, re Read More »
