Electric Wafer Type Hard Seal Butterfly Valve (LQ Type)

 

 

Using precise U-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure, it is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, and municipal construction of water supply and drainage with medium temperature ≤425℃, for regulating flow and Shut off fluid usage. The valve adopts a triple eccentric structure. The valve seat and disc sealing surface are made of cast steel and stainless steel, which has good corrosion resistance and long service life. The valve has a two-way sealing function. Pressure test standard.

 

 

• The valve adopts triple eccentric structure, the valve seat and valve plate are almost free of wear, and it has the sealing function of tighter closing.

• The sealing ring is made of stainless steel, which has the dual advantages of metal sealing and elastic sealing. It has excellent sealing performance under low pressure and high temperature, and has the characteristics of corrosion resistance and long service life.

• The sealing surface of the disc is made of surfacing cobalt-based hard alloy, which is wear-resistant and has a long service life.

• The valve has a bidirectional sealing function, and is not restricted by the flow direction of the medium during installation, nor is it affected by the spatial position, and can be installed in any direction. The drive device can be installed in multiple positions (rotating 90° or 180°), which is convenient for users to use.
