  • Product Description
  • Detailed parameters

  • Midline-type wafer-type rubber butterfly valve is a conventional butterfly valve that is preferred for a short distance between two pipe flanges.

    Characteristics of midline wafer rubber butterfly valve;

    1, the flow resistance coefficient is small, the flow characteristics tend to be straight line;

    2, light weight, easy installation, small opening and closing torque;

    3. It has two-way sealing performance and is not restricted by the flow direction of the medium during installation;

    4, simple structure, easy disassembly and maintenance, 90 ° operation opening and closing quickly;

    5, valve body, valve plate surface spraying epoxy resin, anti-corrosion performance is excellent;

    6, Epoxy resin and rubber comply with the guard standard GB/T17219-1998.

    Midline wafer type rubber butterfly valve uses;

    Can be in the petrochemical, food, medicine, textile, paper, water and electricity, ships, water supply and drainage, smelting and other systems, all corrosive, non-corrosive gas, liquid, semi-fluid and solid powder pipelines and containers as a regulating closure, can be any installation position.
