Worm gear flange butterfly valve

The opening and closing part of the flange butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting. Butterfly valve has the advantages of simple structure, small volume, light weight, small installation size, fast switching.

The center plate butterfly valve with flange connection combines some advantages of eccentric flange butterfly valve and center line clamp butterfly valve, and fills a gap between eccentric flange butterfly valve and center line clamp butterfly valve. The opening and closing part of the valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the function of opening and closing or regulating.
