About Explosion Proof Electric Actuators On/Off
An explosion-proof electric actuator is a kind of rotary actuator that is designed for use in flammable and explosive environments. It is mainly composed of a ball valve, which has explosion-proof electrical components. It can input the relevant power signal to control the valve opening and closing, input a 4-20mA signal to control proportional regulation, and provide various functions such as internal servo operation, opening signal position feedback, position indication, manual operation, simple connection, and so on.
There are four types of electric actuators: rotary, multi-turn, intelligent, and servo. They all convert electricity into linear motion, but the rotary electric actuator is the straight shooter of the bunch—the no-nonsense players that simply do what they say on the tin. The multi-turn electric actuators, on the other hand, are the overachievers of the group—they go multiple rounds, allowing them to move more than just one notch at a time. The intelligent electric actuators, finally, are the Einsteins of the bunch—they deliver the ultimate in precision and control by using a servo motor.
Lastly, the explosion-proof quarter turn electric actuators are designed to automate the operation of ball valves, butterfly valves, plug valves, and dampers in hazard areas. They are built to be ATEX certified and meet the requirements of zones 1 or 2, containing explosive gas atmospheres, or zone 21 or 22, containing combustible dust atmospheres. The explosion-proof electric actuators also come with visual and electrical valve position indicator, manual override, and easy installation using standard ISO 5211 multi-flange mounting.
