Butterfly valve can be used in the pipeline of petroleum, chemical, food, pharmaceutical, paper, hydropower, ship, water supply and drainage, metallurgy, energy and other systems for a variety of corrosive gases, liquids, semi-liquids and solid powder media.

Product features.

Butterfly valve is mainly composed of valve body, rotating shaft, valve plate, valve seat and driving mechanism (handle, worm gear, pneumatic device or electric device), etc. It relies on the driving mechanism to drive the shaft and butterfly plate rotation to achieve the purpose of opening and closing and controlling the flow. Its characteristics are as follows.

(1) Simple and compact structure, small and light, easy to transport, install and disassemble.

(2) 90° opening and closing, rapid switching. Small operating torque, light and labor-saving.

(3) Good sealing performance, long service life, can reach zero leakage.

(4) Select different parts material, can be applied to a variety of media.

(5) The flow characteristics are nearly linear, with good adjustment performance.
