Selection of butterfly valve

Butterfly valve Butterfly plate was installed in the diameter of the pipe. Butterfly's valve of simple structure, small size, light weight. Only a few parts. But rotated 90 ° to quickly open and close, easy operation, and has good flow control characteristics of the valve. Butterfly valve is in fully open position, the thickness of the disc is the resistance of the medium flowing through the valve body only, generated by the valve of the pressure drop is small, it has a better flow control characteristics.

If a butterfly valve used as a flow control is required, major is the correct choice of sizes and types. The structural principle of the butterfly valve is particularly suitable for large diameter valves. Butterfly valves are commonly used for inserting type butterfly's valve and flanged butterfly valves in two ways. Wafer type butterfly valves are valves with a stud is available in between two pipe flanges and flanged butterfly valves are valves with flanged and bolted flanged connections at both ends on the valve in the pipeline flange on the using process.

Butterfly valve, as used for piping system and off and flow control components in petroleum, chemical industry, metallurgy, electricity and is widely applied in many fields. Already known butterfly valve technology, its sealed form uses sealed structure, sealing material for rubber, PTFE, etc. Due to the structural characteristics of, not suited to high temperature, high pressure and high corrosion resistance, wear resistance, and other industries.
