Product Description

Product Description

Butterfly valve
A butterfly valve is a valve whose closing part is a disc, which rotates around the valve shaft to open and close. It is mainly used for cutting and throttling in pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating. The angle from fully open to fully closed of a butterfly valve is usually less than 90°. The butterfly valve and butterfly stem themselves have no self-locking ability. In order to position the butterfly plate, a worm gear reducer must be installed on the valve stem. The use of a worm gear reducer can not only make the butterfly plate have self-locking ability and stop the butterfly plate at any position, but also improve the operating performance of the valve.
