Metal-metal Butterfly Valve
Products Description
Metal-Metal Butterfly Valve is the go-to choice for engineers seeking a simple, compact, and highly durable solution to control flow in pipelines or equipment. Designed for heavy-duty applications, this valve type features a metal-to-metal sealing structure, providing superior performance in high-temperature, abrasive, or corrosive environments where soft seats may fail.
The metal seat and disc design ensures bidirectional sealing, high mechanical strength, and extended service life. With low head loss and reliable sealing characteristics, metal-metal butterfly valves are widely used in water treatment, irrigation, mining, and industrial processing systems.
