Wafer Type Hard Seal Butterfly Valve

Wafer type hard seal butterfly valve

Wafer-type hard-seal butterfly valve: It adopts a precision J-shaped elastic sealing ring and a three-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°C. On industrial pipelines, it is used to regulate flow and carry and break fluids. The valve adopts a triple eccentric structure, and the valve seat and disc sealing surfaces are made of stainless steel with different hardnesses. It has good corrosion resistance, long service life, and two-way sealing function. The product meets the valve pressure test standards.

1. This 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 disc 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. This 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.

7.Manufacturing Standards :JB/T8527-97
