Structural characteristics and applications of welded hard seal butterfly valve

Welded hard-seal butterfly valve structural features: 1, and the pipe butt welding assembly, the user pipe without flange, cost savings; 2, the use of high quality alloy steel welding, with small size. Light weight, good surface quality, high cleanliness, small flow resistance; 3, the use of multi-level design principles, the use of soft and hard metal seal laminated composition. With high temperature, corrosion-resistant, long life and other characteristics. Welded hard seal butterfly valve purposes: welded hard seal butterfly valve is widely used in power plant heating system and the value of cracking the main fan pipe system, steel, metallurgy, chemical and other industrial pipe to cut off or regulate the flow of the role.
