operation, but also has good flow regulation function and closing sealing characteristics at the same time. It is one of the fastest developing valve varieties in the past ten years. Butterfly valves are widely used. The variety and quantity of its use is still expanding, and it is developing to high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, and multi-function of one valve.
