High-Temperature Butterfly Valves: Introduction, Product Features & Technical Parameters

High-Temperature Butterfly Valves, also known as ultra-high-temperature butterfly valves, high-temperature medium butterfly valves, high-temperature fluid butterfly valves, high-temperature gas butterfly valves, high-temperature liquid butterfly valves, and high-temperature flue gas butterfly valves, refer to valves that adopt high-temperature resistant stainless steel or 2520 material, as well as high-temperature resistant special alloy steel materials. These materials ensure that the butterfly valves can operate stably under high-temperature working conditions, with a maximum operating temperature of up to 1650℃. They are used for opening and closing high-temperature media such as high-temperature gas, flue gas, and high-temperature liquid.

High-Temperature Butterfly Valves are widely used in cement industry, environmental protection projects, environmental protection equipment, flue gas desulfurization, waste heat recovery, metallurgy, mining, electric power and other production processes. They change the flow rate of high-temperature media in pipelines according to different control signals (worm gear, electric, pneumatic), thereby realizing automatic remote control of industrial production processes.

Product Features of High-Temperature Butterfly Valves

• Simple structure, sensitive action, and easy to use. It can be operated by worm gear, electric or pneumatic, meeting the needs of automatic program control and remote control.

• Large flow capacity, easy maintenance, reliable working performance, and has the function of regulating the flow rate and velocity of the medium.

• Lined with high-temperature refractory materials, with rolling bearings and lubrication system at the outer end. Water-cooled structure design can be adopted for rapid heat dissipation.
