Working Principle Of Butterfly Valve

- Jun 24, 2019-

Butterfly valve is a kind of valve that opens, closes or regulates the flow of medium by turning the disc opening and closing parts around 90 degrees. Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and fast in operation, but also have good flow regulation function and sealing characteristics. They are one of the fastest growing valve varieties in recent decades. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large caliber, high sealing, long life, excellent regulation characteristics and multi-function of a valve. Its reliability and other performance indicators have reached a high level.

With the application of synthetic rubber to butterfly valves, the performance of butterfly valves has been improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, low cost and so on, it can choose synthetic rubber with different properties according to different application requirements to meet the operating conditions of butterfly valves.
