Development and progress of three eccentric butterfly valves
Update time：2025.04.01 Views：19
In the past, due to the low level of domestic valve design and manufacturing, many people had a large preference for butterfly valves, but developed countries such as Europe and the United States have been vigorously promoting and using butterfly valves. At present, butterfly valves are no longer the past.
The development of butterfly valve has undergone the concentric development process of single eccentric butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve.
The three-eccentric butterfly valve has excellent performance, even more basic zero leakage, which in theory can do, but in reality, rely mainly on its precision design and precision manufacturing.
The design of the three-eccentric butterfly valve not only complies with the API standards, but also complies with BS5155, ASME SEC VIII and other standards, making it applicable to more fields. The three-eccentric butterfly valve is designed without dead zones and has the characteristics of dual safety structure, replaceable sealing pair, thin plate seat structure, and inherent fire-resistant structure.
