Three eccentric butt-weld hard-sealed pneumatic butterfly valve, butt-weld hard-sealed pneumatic butterfly valve, pneumatic butterfly valve

 Product Features 

1, clamp metal multi-level sealing butterfly valve clamp connection structure is simple, convenient installation and disassembly, light weight characteristics. Metal hard seal butterfly valve with three eccentric seal structure, valve seat and butterfly plate almost no wear, with more tight sealing function.

2, the sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic seal, no matter in the case of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics.

3. The sealing surface of the butterfly plate is hardfaced with cobalt-based carbide, and the sealing surface is wear-resistant and has long service life.4, the large size of the butterfly plate adopts quilting structure, high strength, large flow area, small flow resistance.

5, the metal hard seal butterfly valve has a two-way sealing function, the installation is not limited by the flow of the medium, nor by the influence of the space position, can be installed in any direction.

6, the driving device can be multi station (rotation 90° or 180°) installation, convenient for users to use.
