The metal rigid sealed butterfly valve's butterfly plate is mounted along the diameter of the pipeline. Inside the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with an angle of rotation between 0° and 90°. When rotated to 90°, the valve is fully open.

1、The metal hard-seated butterfly valve utilizes a three eccentric sealing structure, with the valve seat and butterfly plate experiencing minimal wear, featuring a sealing function that becomes tighter as it is closed more.

2. Seals are made of stainless steel, offering both the advantages of metal hard sealing and elastic sealing. They maintain excellent sealing performance in both low and high temperatures, and feature corrosion resistance and a long service life.

3. The butterfly plate sealing surface is made of surfacing cobalt-based hard alloy, offering excellent wear resistance and a long service life.

4. Large-scale butterfly plates feature a truss structure, offering high strength, a large flow area, and low flow resistance.

5. This valve features bidirectional sealing capability, allowing for installation without restriction by the medium's flow direction or spatial position, and can be mounted in any direction.
