The electric explosion-proof butterfly valve is composed of an explosion-proof electric actuator and a butterfly valve. It can be operated by inputting a specific power supply. It can also have a built-in servo module. It can control the operation of the regulating quantity by inputting a control signal and a single-phase power supply, and can control the opening and closing of the valve at any position. The explosion-proof electric butterfly valve has the advantages of strong function, small volume, reliable performance, simple matching and large circulation capacity. It is especially suitable for occasions where the medium is viscous and contains particles and fibers. It can be widely used in the process automatic control system of food, environmental protection, light industry, chemical industry, teaching equipment, papermaking, electric power and other industries.
