How Butterfly Valves Work
Butterfly valve is a kind of valve that uses a disc opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, simple and rapid operation, but also has good flow regulation function and closing sealing characteristics at the same time. One of the fastest 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 performance, long life, excellent adjustment characteristics, and multi-function of one valve. Its reliability and other performance indicators have reached a high level.
With the application of chemically resistant synthetic rubber on the butterfly valve, the performance of the butterfly valve has been improved. Since synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, and low cost, synthetic rubber with different properties can be selected according to different use requirements to meet the working conditions of butterfly valves.
