Features of single eccentric sealing butterfly valve: 1. The structure is more complicated than the centerline sealing butterfly valve​, and the cost is slightly higher;
The sealing principle of single eccentric sealing butterfly valve:1. Structural features: The center of rotation of the valve disc (the center of the valve shaft) is located on the centerline of the valve body, and forms an α dimension offset with the sealing section of the valve disc.
The sealing principle of the centerline butterfly valve is to ensure that the sealing surface has a suitable surface roughness when processing the valve disc, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during molding.
According to the country’s specific arrangement for Dragon Boat Festival Holiday in 2022, our company has notified the holiday arrangements as following:Jun. 3 – Jun. 5 will be closed for holiday and we will return office at Jun. 6. Happy holidays to all friends in advance!
In order to meet the requirements of industrial applications such as high and low temperature, strong erosion, and long life, metal-sealed butterfly valves have been greatly developed in recent decades.
