A series of butterfly valves with PTFE lining, diameter DN40–DN1800; complete with manual, pneumatic ()

Butterfly valve is with the stem rotation of the butterfly plate for opening and closing parts, to achieve the opening, closing and adjustment of the valve. In recent years, butterfly valve has taken
sealing performance as the main indicator for flow in pipelines, and favored by the market. In evaluation in addition to throttle and intercepting addition, the butterfly valve has the advantages of small volume , light weight, simple structure, and so on. Compared with gate valves with the same parameters, the average weight reduction is up to
30~50%.The butterfly plate can be rotated 90 °to achieve the opening and closing process. Also, due to the approximately equal media forces acting on the butterfly plates on both sides of the shaft and the
opposite torque, the opening and closing torque is small.
