Double Flanged Butterfly Valve

A double flanged butterfly valve is a type of valve that is commonly used in industrial and commercial piping systems. The valve features a circular disc-shaped closure element, known as a butterfly, which rotates around a central axis to open or close the valve. The butterfly is connected to a stem operated by an actuator, such as a handle or a motor, to rotate the butterfly and control the fluid flow.

The double flange design of the valve refers to the presence of flanges on both sides of the valve body. These flanges are used to connect the valve to the piping system and provide a secure and leak-tight seal. The double flange design allows for easy installation and maintenance of the valve and allows for a high-pressure rating.

The valve can be used to control the flow of liquids or gases and can be used in a variety of applications, including water treatment, chemical processing, and oil and gas production. The double flanged butterfly valves are often used in larger pipelines as they have a high flow capacity and are suitable for high-pressure systems.

Advantages of double flanged butterfly valve:

  • It has a compact design which makes it suitable for use in tight spaces
  • Easy to install and maintain
  • This design allows high pressure rating
  • It has low pressure drop, which helps to reduce the energy consumption
  • The valve is relatively inexpensive

Disadvantages of the double flanged butterfly valve:

  • It is not suitable for use in extreme temperature conditions
  • It can stick due to corrosion, rust, and other build-ups, making it difficult to operate.
  • It is not recommended for high-pressure drops
