Product Description

    As one of the most common valves, the wafer type electric butterfly valve is suitable for the medium of water, oil and other liquid medium, whose disc supports frame structure with high strength, large flow area, and small flow resistance. With whole baking finish surface, the valve can effectively prevent rusting, and is suited to different medium by changing high quality seal ring or seal material. Owning two-way seal function,this valves can be installed in any direction and not be affected by the spatial position and the medium flow.
   ★Small volume and light weight, easy to disassemble and maintain, and can be installed in any position
  ★Small pressure drops, Large flow capability.
  ★The patent positioning technology
  ★Small operating torque, energy saving.
  ★Linearity flow characteristics，Excellent regulated performance.
  ★Simple and compact structure
  ★Long service life, good seal performance.
    More than *0,**0 operation life without fault, keep your system operating safely and reliably.
