Butterfly valve flange type structure and working principle

The butterfly plate of the flange butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and its rotation angle is between 0° and 90°.When the butterfly plate rotates to 90°, the valve is fully open.

Butterfly flange valve features and advantages:

When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated is very small and it has good flow control characteristics.In addition, the flange butterfly valve also has the characteristics of simple and compact structure, small operating torque, and rapid opening of 90° rotation.

Refer to EPDM, which is a commonly used high-performance sealing material with excellent corrosion, high temperature and pressure resistance.

Application areas :

Flange butterfly valves are suitable for industries such as water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and light textiles with temperatures ≤120°C or ≤150°C and nominal pressures ≤1.6MPa.It is especially suitable for two-way sealing and situations where the valve body is prone to rust. It can be used as a flow regulating and intercepting medium.

Application areas

Production Process:

 Flange butterfly valve has become an indispensable and important component in industrial pipeline systems due to its excellent performance and wide range of applications.
