Triple eccentric butterfly valve DN600 characteristics

1. The butterfly plate sealing ring of the metal hard seal butterfly valve is a soft and hard laminated metal sheet, which has the dual advantages of metal seal and elastic seal. It has excellent sealing performance no matter in low or high temperature conditions.

2. Triple eccentric structure, almost no friction between the valve seat and the butterfly plate, with more close more tight sealing function.

3. The sealing surface of the valve body is made of surfacing stainless steel and cobalt-based hard alloy. The sealing surface is wear-resistant and has long service life.

4. Metal hard seal butterfly valve unique structure, flexible operation, labor-saving, convenient, not affected by the medium pressure of high and low, reliable sealing performance.
