Butterfly Valve

Butterfly valve takes disc as its closure member, the disc rotates around the valve shaft to realize opening and closing, and it is mainly used for cutting off and throttling fluid in pipelines. The closure member of a butterfly valve is a circular disc, which rotates around its own axis inside the valve body to achieve opening, closing and regulation. The rotation angle of a butterfly valve from fully open to fully close is generally less than 90 degrees. The disc and valve stem have no self-locking capacity, so a worm gear or handle needs to be installed on the valve stem for disc positioning.
