Butterfly valve features and scope of application

Butterfly valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal, radioactive media and other types of fluids. It mainly cuts and throttles the pipe. The opening and closing part is a disc-shaped disc that rotates around its own axis in the valve body for opening and closing or adjusting purposes.

A butterfly valve is a valve that opens, closes, or regulates medium flow by reciprocating a disc switch element by approximately 90 degrees. It is not only simple structure, small volume, light weight, less material consumption, small installation size, small driving torque, simple and quick operation, but also has a good flow regulation function and close sealing characteristics. The variety and number of its uses continue to high temperature, high pressure, large diameter, high sealing performance, long service life, excellent regulating characteristics and a valve multi-purpose direction development.

Butterfly valve is suitable for flow regulation. Because the pressure loss in the pipeline is large, about three times that of the gate valve, the influence of the pressure loss on the pipeline system should be fully considered in the selection, and the strength of the butterfly valve under the pressure of the pipeline medium should be considered when the butterfly valve is closed. In addition, the operating temperature limits of the elastic seat material at high temperatures must be considered.
