Electric Gas-Specific Butterfly Valve

The electric gas butterfly valve consists of a gas butterfly valve and an electric actuator connected mechanically. It is used in gas pipelines and gas generators, handling media such as blast furnace gas, high-temperature gas, and ambient-temperature gas. Electric gas butterfly valves require explosion-proof electric actuators. Gas butterfly valves are multi-stage triple-eccentric hard-seal butterfly valves or triple-eccentric PTFE-seal butterfly valves. Designed based on the three-dimensional eccentricity principle, they achieve bubble-tight sealing.
