Butterfly valve features and uses

The characteristics of the butterfly valve 1, Direct welding with the pipe assembly, the user pipe without flange, cost savings; 2, using high quality alloy steel welding, with small size, light weight, good surface quality, high cleanliness, 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. The use of butterfly valve Welded hard-sealed 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 for cutting off or regulating the role of flow.
