    Air Operated Pinch Valve

    Air operated pinch valve are designed to provide efficient and reliable control of abrasive, corrosive, and fibrous materials found in various industrial applications. These innovative valves are suitable for use with a wide range of materials, including cement, silo, sand, mineral materials, limestone, clay, marl, sand, and slurry.

    Key Features:

    • Wear-resistant: The valve’s body is constructed from robust materials like aluminum alloy, cast iron, and stainless steel, ensuring long-lasting durability and resistance to wear.
    • Corrosion-resistant: These pinch valves are built with materials that provide excellent resistance to corrosion, ensuring their longevity in the presence of abrasive and corrosive materials.
    • Long life: With a combination of wear and corrosion resistance, air operated pinch valves provide a long service life, reducing maintenance costs and minimizing downtime in industrial processes.
    • Smooth channel: The smooth internal channel of the valve ensures efficient flow of materials and helps to prevent buildup or blockages.
    • Flange accommodation: These valves can be easily integrated with various flange standards, including EN 1092 PN 6/PN10/PN16, ASME Class 150, AS 4087 PN 10/ PN 16, and JIS 5K/10K.

    Customizable Sealing Ring:

    The sealing ring of the pinch valve can be customized according to specific application requirements. Available materials include:

    • Wear-resistant natural rubber
    • Natural rubber
    • Food industry high-temperature resistant natural rubber
    • Ethylene-propylene rubber
    • Ding Qing Nitrile, EPDM, VITON/FPM Silicone
    • Silicone rubber
    • Fluorine rubber, chloroprene rubber (Neoprene)
    • Chlorosulfonated polyethylene rubber (Hypalon/CSM), butyl acrylate (Butyl), and other materials as needed.

    Please specify the desired material for the sealing ring when placing an order.


    Pneumatic pinch valve are perfect for various industries that deal with abrasive, corrosive, or fibrous materials, such as:

    • Cement production
    • Mineral processing
    • Mining
    • Agriculture handling of fertilizers
    • Water treatment facilities handling sludge
