3 Inch Aluminum Pneumatic Pinch Valve offers a cost-effective solution to flow control problems. The VA series air operated pinch valve is 2-way normally closed and normally open pressure-operated pinch valves designed for use with high-purity liquids in biotech applications. Hermetic separation of the control mechanism and the fluid within the tubing prevents contamination, assuring the maximum purity of liquids. As one of the famous China pneumatic pinch valve manufacturers, our 3 Inch Aluminum Pneumatic Pinch Valve has the best quality.
The 3-inch aluminum pneumatic pinch valve from the VA series is 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 air operated pinch valves can be equipped with either natural rubber food-safe sleeve, natural rubber abrasion resistant sleeve, or EPDM sleeve. These 3-inch aluminum pneumatic 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).

When the control gas does not input into the pneumatic pinch valve, the cavity between the rubber sleeve and the valve body communicates with the atmosphere, and the rubber sleeve is in an outwardly tensioned state by the fluid pressure. Because there are reinforced plies arranged at a certain angle in the sleeve, the axial and radial pressures of the sleeve are balanced with each other, so the length and diameter of the sleeve will not change due to the fluid pressure. When the control gas enters the cavity between the sleeve and the valve body, the sleeve is deformed and intercepted under the control gas pressure.
When compressed air (pressure difference is 2 bar) enters the valve body of the pneumatic pinch valve, the specially-made inner liner with high resilience is compressed to produce a lip-type closure. This extremely increases the service life of the inner sleeve. In this case, the pneumatic pinch valve is closed, so that the medium flow can be shut down 100%. Its working pressure varies depending on the nominal diameter and ranges from 2-6 bar. When the compressed air is interrupted, the specially-made inner liner expands rapidly under the dual effects of its own rebound force and medium pressure, and then the valve is fully opened.
Pneumatic pinch valve, also known as pinch valve, squeeze valve, bladder valve, hose valve, airbag valve, pinch off valve, etc. The pinch valve rubber sleeve (inner bush) is an important part of the pinch valve and the core of the pinch valve. It provides corrosion resistance, wear-resistance, and p Read More »

Air operated pinch valves are also known as pneumatic pinch valves and rubber sleeve valves. Because the valve core part uses a hose, its airtightness, corrosion resistance, and wear resistance are far superior to metal valves. Therefore, it is widely used in smelting, mining, electric power, chemic Read More »
