Overview of Butterfly Valve(Part 1)

Butterfly valve is a kind of valve that uses a disc type opening and closing member to reciprocate about 90° to open, close and adjust the fluid channel.

Butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, but also has small driving torque, easy and fast operation, and also has good flow adjustment function and closing sealing characteristics. It’s one of the fastest growing valve varieties in recent decades. Especially in industrialized countries such as the United States, Japan, Germany, France, and Italy, the use of butterfly valves is very popular, meanwhile the variety and quantity of butterfly valves are still expanding. And develop in the direction of high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment characteristics and multi-function in one valve, its reliability and other performance indicators have reached a high level, and have partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valves will become the dominant valve form in the foreseeable short period of time, especially in the fields of large and medium caliber, medium and low pressure applications.

The original butterfly valve is a simple, loosely closed flapper valve, commonly used as a flow regulating valve and damping valve in water piping systems.

With the application of chemically resistant synthetic rubber on the butterfly valve, the performance of the butterfly valve has been improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming and low cost, and synthetic rubber with different properties can be selected according to different use requirements to meet the working conditions of butterfly valves, so It is widely used in the manufacture of liners and elastic seats for butterfly valves.

Because polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, not easy to age, low friction coefficient, easy to form, stable size, and can also be filled and added with appropriate materials to improve its comprehensive properties, to obtain better strength, butterfly valve sealing materials with a lower coefficient of friction overcome some limitations of synthetic rubber, so high-molecular polymer materials represented by polytetrafluoroethylene and their filling modified materials have been widely used in butterfly valves. The performance of butterfly valve has been further improved, meanwhile butterfly valves with wider temperature and pressure ranges, sealing performance and longer service life have appeared.
