Manual flanged type metal sealing butterfly valve
The manual flanged type metal sealing butterfly valve has the characteristics of compact structure, small volume, light weight, convenient operation, reliable performance, simple maintenance, anti-aging, anti-irradiation, durability, long service life, high temperature resistance and high pressure, wide application range and the like,
Characteristics of Butterfly Valve with Manual Flange hard Seal Butterfly Valve
- The valve adopts a triple-eccentric sealing structure, and the valve seat and the butterfly disc are almost free of wear,and the valve seat has the sealing function with more closing and tightening
- The sealing ring is made of stainless steel, and has the dual advantages of metal hard seal and elastic sealing, and has the characteristics of corrosion resistance, long service life and the like,
- The sealing surface of the disc is made of hard facing cobalt-based hard alloy, and the sealing surface is resistant to wear and has long service life.
- The large size butterfly plate adopts truss structure, which has high strength, large over current area and small flow resistance.
- The valve has bi-direction sealing function,and is not limited by the flow of medium during installation, and is not affected by the space position, and can be installed in any direction.
- The drive device can be installed at multiple stations (rotating 90 or 180 ) for easy use by users
Manual flanged hard sealed butterfly valves are widely used in thermal pipelines,boiler auxiliary systems, petrochemical and metallurgical industries to cut off and regulate all kinds of non-corrosive and corrosive media.
