Explosion proof electric butterfly valve is a special control equipment for inflammable and explosive occasions. Its explosion-proof grade is ExdIIBT4 / cT4 or CT5. It has the advantages of stable quality, good explosion-proof performance, safety and reliability. And the connection forms and structural forms are diversified, which are widely used in food, environmental protection, light industry, petroleum, chemical industry, water treatment, electric power and other industries. It can not only be used for two position control of switch, but also input 4-20madc, 1-10V DC signal and power supply, control the opening of valve, and realize the adjustment of pressure, flow, temperature, liquid level and other parameters.
The explosion-proof electric butterfly valve can withstand the explosion pressure of the internal explosive mixture and prevent the explosion transmission with the surrounding explosive mixture. The shell is hard aluminum alloy with strong corrosion resistance and protection grade of IP67. The motor is a totally enclosed squirrel cage motor, with large torque, small inertia force and F insulation grade. The built-in overheat protection switch can prevent the motor from being damaged when the electric actuator is locked and the motor is overheated, and it has a handwheel design, which can be used for operation when the power is cut off, ensuring safety and reliability.
The explosion-proof electric butterfly valve is driven by 380V / 220V / DC24V and other power sources, but different voltage and control forms, corresponding wiring methods are also different, users need to have a detailed understanding and cognition!
