Knowledge of butterfly valve

Yuhuan valve manufacturers have many kinds of valves, among which butterfly valve is a kind of valve which uses disc type opening and closing parts to open, close and adjust the fluid channel by reciprocating rotation of about 90 degrees.

Butterfly valve has many advantages. First of all, it is simple in structure, small in volume, light in weight and less in material consumption. In addition, in terms of function, the butterfly valve is relatively fast in opening and closing, with small flow resistance, which can be used for medium with suspended solid particles, as well as powder and granular medium. Therefore, butterfly valve is widely used in the gas pipeline and water channel of metallurgy, light industry, electric power and petrochemical system.

Of course, the real object has two sides, and butterfly valve also has some disadvantages, that is, the flow regulation range is not large, and due to the limitations of butterfly valve structure and sealing materials, it is not suitable for high temperature and high pressure pipeline system.
