Butt-welding Type Hard Seal Butterfly Valve is a shut-off device used for full open and full close operations, widely applied in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction. Its main features include:
Sealed Structure: Precision-engineered J-shaped elastic seals and triple eccentric multi-layer metal hard sealing structure for excellent corrosion resistance and long service life.
Applicable Temperature Range: Suitable for environments where the medium temperature is ≤ 425℃.
Bidirectional Sealing Function: Equipped with bidirectional sealing, unrestricted by the flow direction of the medium, easy to install.
Wear-resistant: The sealing surface is lined with cobalt-based hard alloy, offering excellent wear resistance and a long service life.
Structural Features: Compact design, small size, light weight, easy to install and operate.
Drive Method: Available in manual, worm gear, pneumatic, electric, and various other drive modes._
Application Fields
Wafer-type hard-seated butterfly valves are widely used in metallurgy, power, petrochemicals, water supply and drainage, and municipal construction for regulating flow and cutting off fluids. Their excellent sealing performance, high-temperature resistance, and corrosion resistance make them excel in these fields.
