Features of Electric Flanged Butterfly Valves:
1. The overall painted finish effectively prevents corrosion, and by simply changing the sealing material of the valve seat, it can be used with different media.
2. This valve has a bidirectional sealing function, and its installation is not affected by the direction of media flow or spatial location; it can be installed in any direction.
3. This valve has a unique structure, is flexible in operation, labor-saving, and convenient.
4. This valve adopts a double eccentric structure, providing a tighter seal as it closes, ensuring reliable sealing performance.
5. The sealing pair uses a combination of stainless steel and nitrile oil-resistant rubber, resulting in a long service life.
6. The rubber sealing ring can be located on the valve body or the butterfly plate, suitable for different media, allowing users to choose the appropriate method.
7. The butterfly plate uses a frame structure, providing high strength, a large flow area, and low flow resistance.
