Introduction to D43H-150LB American standard flange hard seal butterfly valve

D43H-150LB American standard flange hard seal butterfly valve manual flange hard seal butterfly valve, the nominal pressure range is PN10~PN40. D43H manual multi-layer metal hard seal butterfly valve adopts precision J-shaped elastic sealing ring and triple eccentric multi-layer metal hard seal structure. It is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction where the medium temperature is ≤425℃. It is used on industrial pipelines such as to regulate flow and carry and break fluids.

Features of D43H-150LB American standard flange hard seal butterfly valve

1. The metal hard-seal butterfly valve adopts a three-eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as you look.

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance no matter under low or high temperature conditions, and has the characteristics of corrosion resistance and long service life.

3. The sealing surface of the butterfly plate is made of cobalt-based hard alloy surfacing. The sealing surface is wear-resistant and has a long service life.

4. The large-sized butterfly plate adopts a quilted frame structure, which has high strength, large flow area and small flow resistance.

5. The metal hard-seal butterfly valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction.

6. The driving device can be installed in multiple positions (rotated 90° or 180°), making it convenient for users to use.
