Product Introduction
WESDOM could provide various butterfly valves which can be widely applied in all many kind of industrial fluids. The sizes from DN25~DN2400 are all available. The standard we can comply DIN, JIS, GB, API 609, etc. CHOOSE WESDOM, CHOOSE QUALITY!
This product mainly consists of body, stem, disc, seat AL-Bronze bushings, etc. The rotation of actuating device makes the stem and disc revolve, which ensures on-off operations and flow control. The rotation of the actuating device ensures dependability and position disc control and position disc control and water flow control. Rotate the handle wheel clockwise, the valve is closed.

Detailed parameters

wesdom butterfly valve

  • The anti-dew butterfly valve refers to the butterfly valve which body is made of aluminum alloy.
  • The advantages of the anti-dew butterfly valve is that the aluminum alloy body has strong corrosion resistance and light weight.
  • The spherical structure around the butterfly plate is helpful to reduce the friction torque with the valve seat.The butterfly plate and valve shaft are made of stainless steel, which increases the anti-dew ability while reducing heat conduction and preventing the driving device from being too low.
  • The housing of the driving device is made of aluminum alloy, which is light in weight and fast in heat dissipation, which is beneficial to the emission of moisture.
  • The use of vulcanized rubber seat and steel long valve neck structure further reduces heat conduction. Anti-condensation butterfly valve, ultra-light aluminum alloy body, small torque, easy to use and install, suitable for air-conditioning, industrial water treatment equipment, has a strong anti-condensation function.
  • The use of aluminum alloy die-cast valve body can effectively prevent corrosion.
  • The outer surface of the anti-condensation butterfly valve adopts anti-condensation paint, which can increase the hydrophilicity and facilitate the diffusion of moisture.
  • The surface of the coating has a grid-like fine structure, which increases the surface area and facilitates the emission of moisture.
