HK59-D-V Ductile Iron Wafer Flanged Pneumatic Ventilation Butterfly Valve

The pneumatic ventilation butterfly valve is made of steel plate by welding. It has the advantages of short structure size, light weight, convenient installation, etc. the driving torque of the valve is small, the opening and closing are flexible, and the operation is convenient. The valve body is provided with an oil sealing ring, and there is no visible gap between the sealing pairs, so the leakage rate is small.

  • Model: HK59-D-V
  • Size Range: 4''~48''
  • Pressure Range: 0.05MPa to 0.6MPa
  • Material: Cast Iron

Product features:

    The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent the jamming caused by the hot expansion and cold contraction. The valve can be equipped with a variety of driving devices, such as manual device, worm gear drive device, pneumatic device, electric device. It is widely used in industrial pipelines such as gold control, chemical engineering, electric power, building materials, mines, etc., and it can control or regulate the medium gas.

There is no connecting rod and bolt inside, which is reliable and long service life. It can be installed in multiple stations, not affected by the flow direction of media
