The Role of Single Eccentric Butterfly Valve in Extrusion Prevention

A solution to the extrusion problem in butterfly valves has been found with the production of the single eccentric butterfly valve. This new valve features a structural deviation in the valve stem from the center of the disc, effectively dispersing and reducing excessive extrusion between the upper and lower ends of the disc and the valve seat.
 
The concentric butterfly valve has long been known to have issues with extrusion between the disc and the valve seat. To address this, the single eccentric butterfly valve was developed to provide a solution to the problem. This new valve design prevents the upper and lower ends of the disc from becoming the axis of rotation, reducing the risk of extrusion and improving overall performance.
 
However, it is important to note that while the single eccentric structure of the valve does address the extrusion issue, it does not eliminate the scratching phenomenon between the disc and the valve seat during the entire switching process of the valve. This drawback means that the single eccentric butterfly valve may not be suitable for all applications.
 
Despite this limitation, the single eccentric butterfly valve is still a valuable addition to the valve industry, especially for applications that are similar to those of the concentric butterfly valve. The unique design of the single eccentric butterfly valve makes it an effective solution for industries facing extrusion issues with traditional butterfly valves.
 
While the application range of the single eccentric butterfly valve is not as wide as that of the concentric butterfly valve, it still serves as an important alternative for industries looking to address extrusion problems in their valve systems. With further development and refinement, the single eccentric butterfly valve has the potential to become a widely used and valuable tool in the valve industry.
