Double flange butterfly valve

The double flange butterfly valve has a compact structure, easy 90 ° rotary switch, sealing, and long service life. It is widely used in water plants, power plants, steel mills, papermaking, chemical, catering and other systems for water supply and discharge, as well as for regulating and shut-off purposes.

Double flange butterfly valve refers to a type of valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. It mainly plays a role in cutting off and throttling on pipelines, also known as a flap valve. It is a structurally simple valve. The butterfly valve opening and closing component is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening, closing, or adjusting. Butterfly valves are suitable for pipelines transporting various corrosive and non corrosive fluid media in engineering systems such as furnaces, coal gas, gas, liquefied petroleum gas, urban gas, cold and hot air, chemical smelting, and power generation environmental protection. They are used to regulate and cut off the flow of media.

Characteristics of double flange butterfly valve:

1. The double flange butterfly valve adopts a double eccentric structure, which has a tighter sealing function and sealing performance as it is closed.

2. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life.

3. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from.

4. The butterfly plate adopts a frame structure, with a large overcurrent area and low flow resistance.

5. The overall baking paint can prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced.

6. Double flange butterfly valves have bidirectional sealing function, and are not controlled by the flow direction of the medium or the spatial position during installation. They can be installed in any direction.

7. Double flange butterfly valve structure, flexible operation, labor-saving, and convenient.
