Talking About The Development History Of Butterfly Valve

I talked a lot about butterfly knowledge with you before, and today butterfly valve manufacturers will talk to you about the development history of butterfly valves.

1. With the application of chemically resistant synthetic rubber to butterfly valves, the performance of butterfly valves can be improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, low cost, etc., synthetic rubber with different properties can be selected according to different usage requirements to meet the operating conditions of the butterfly valve. It is widely used in the manufacture of butterfly valve lining and elastic valve seat.

2. Because polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, not easy to age, low friction coefficient, easy to form, stable in size, and it can also be filled and added with appropriate materials to improve its comprehensive performance and better strength , The butterfly valve sealing material with lower friction coefficient overcomes part of the limitations of synthetic rubber. Therefore, polymer polymer materials represented by polytetrafluoroethylene and their filling modified materials are widely used in butterfly valves, thereby improving the performance of butterfly valves. Further improvement, a butterfly valve with a wider temperature and pressure range, sealing performance and longer service life appeared.

3. In order to meet the use requirements of industrial applications such as high and low temperature, strong erosion, long life, etc., in the past ten years, metal sealing butterfly valves have developed greatly. With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance, and high strength alloy materials in butterfly valves, metal sealed butterfly valves have been widely used in high and low temperature, strong erosion, long life and other industrial fields. The butterfly valve with large diameter (9750mm), high pressure (2.2kN/cm2), and wide temperature range (-102～606℃) brings the technology of butterfly valve to a whole new level.

The above is the knowledge shared by butterfly valve manufacturers. I hope it will be helpful to you. If you want to know more, please contact us as soon as possible.
