How the Butterfly valve works

Butterfly valve is a kind of valve that uses disc type opening and closing parts to turn back and forth about 90° to open, close or adjust the flow of medium. Butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast in operation, but also has good flow regulation function and closing and sealing characteristics at the same time. One of the fastest growing valve varieties. 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 diameter, high sealing, long life, excellent adjustment characteristics, and multi-function of a valve. Its reliability and other performance indicators have reached a high level.

Butterfly valve

The performance of the Butterfly valve is enhanced with the application of chemically resistant synthetic rubber on the Butterfly valve. Since synthetic rubber has the characteristics of corrosion resistance, erosion resistance, stable size, good resilience, easy forming, and low cost, synthetic rubber with different properties can be selected according to different application requirements to meet the working conditions of Butterfly valve.
