Product Features

 

1. This valve utilizes a triple-offset sealing structure; there is virtually no wear between the valve seat and the butterfly plate, and the sealing performance improves as the valve closes tighter.

 

2. The sealing ring is made of stainless steel, combining the advantages of both metal-to-metal hard sealing and elastic sealing. It offers excellent sealing performance across both low and high temperatures, as well as corrosion resistance and a long service life.

 

3. The sealing surface of the butterfly plate features cobalt-based hard alloy overlay welding, ensuring wear resistance and durability.

4. Large-sized butterfly plates employ a truss structure, providing high strength, a large flow area, and low flow resistance.

 

5. The valve features bidirectional sealing capabilities; installation is not restricted by the direction of media flow or spatial orientation, allowing for installation in any position.

 

6. The actuating device supports multi-position installation (rotating 90° or 180°), offering greater convenience for the user.
