Where Can I Find The Current Threaded Ball Valve?

The butterfly disc of a Threaded Ball Valve is installed diametrically along the pipe. Within the cylindrical passage of the hard-seal ball valve body, the disc-shaped disc rotates around its axis, with rotation angles ranging from 0° to 90°. When the disc reaches 90°, the valve is fully open. Features of new, long-life stainless steel butterfly valves and problems encountered during use. Currently, hard-seal ball valves and hard-seal butterfly valves are widely used in many fields, including petroleum, chemical, metallurgy, and hydropower, as components for on-off and flow control in pipeline systems. Conventional butterfly valve technology typically employs a sealing structure, using materials such as rubber and polytetrafluoroethylene. Due to structural limitations, these valves are not suitable for applications requiring high-temperature, high-pressure, corrosion-resistant, or wear-resistant performance.

A relatively advanced butterfly valve is the triple-eccentric metal hard-seal butterfly valve, in which the valve body and seat are integral components, and the seat sealing surface is welded with a heat- and corrosion-resistant alloy.

The hard-seal ball valve features an eccentric metal-to-metal seal structure, offering metal-to-metal sealing. Metal-to-metal sealing rings and stainless steel and graphite composite plate sealing rings are interchangeable. In addition to electric, hard-seal butterfly valves can be driven manually, by worm gear, or pneumatically. These valves are typically installed horizontally.
