  • Product Description
  • Detailed parameters
  • The rubber soft seal gas butterfly valve adopts the double eccentric structure of the rubber seal butterfly valve as a whole, and the two-way sealing performance is more stable. It is the first choice for the transformation, maintenance and matching of the old pipeline.

    Characteristics;

    1. This series of gas butterfly valves adopt a double eccentric structure, the valve seat is made of stainless steel, and the sealing pair can be opened and closed instantly, which reduces process friction and extends the service life of the valve.

    2. This series of gas butterfly valves adopt a half-shaft structure, the disc plate has high strength, large flow area, small flow resistance, and energy saving.

    3. The rubber sealing ring can adjust the interference of the sealing pair through the pressure plate, so that the sealing specific pressure is controlled in the best state. When the rubber sealing ring is damaged, the pressure plate can be removed from the pipeline to replace it.

    4. This series of butterfly valves are equipped with the latest synchronous indicating mechanism, which can clearly indicate the valve opening and closing status in a convenient and conspicuous position.

    Gas butterfly valve uses, can be used in petrochemical, food, medicine, textile, papermaking, water and electricity, ships, water supply and drainage, metallurgy and other systems, all corrosive, non-corrosive gas, liquid, semi-fluid and solid powder pipelines and containers as regulation and closure, can be installed in any position.

    Rubber soft sealing gas disc valve is mainly divided into worm double eccentric flange rubber butterfly valve, pneumatic double eccentric flange rubber butterfly valve, electric double eccentric flange rubber butterfly valve.
