Hard Seal Triple Eccentric Butterfly Valve
Hard Seal Triple Eccentric Butterfly Valve

Product Features

1. Eccentric hard seal structure, almost no wear on valve seat and disc, good sealing performance.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance at low and high temperatures, corrosion resistance and long service life.
3. The sealing surface of the butterfly plate is made of welded cobalt-based hard alloy. The sealing surface is resistant to wear and has a long service life.
4. The hard-sealed butterfly valve can be designed to have a two-way sealing function, which is not restricted by the flow direction of the medium and is not affected by the position of the space during installation.
5. The driving device can be installed in multiple positions (rotated 90 ° or 180 °), which is convenient for users.
