Explosion-proof Electric Ball Valve Wiring Diagram Description And Control Mode

Explosion-proof electric ball valve is a kind of equipment that can prevent the explosion of the pipeline, that is, the electrical components meet the explosion-proof standards, can be used for explosion-proof occasions, not only can be applied to general oil, natural gas, environmental protection, water treatment, etc., including the chemical industry, oil and other working conditions are more severe places, Explosion-proof grades such as common ExdIIBT4, ExdIICT5, ExdIICT6 and so on. Explosion-proof electric ball valve through 380V/220V/DC24V power supply as the driving power supply, with switching signal or analog signal (4-20mA, 1-10V DC, 1-5V DC) as the control signal, can make the valve move to the required position, to achieve its automatic control. Different voltage and control forms, wiring methods are not the same, the user needs to understand and understand in detail! Explosion-proof electric ball valve can withstand the explosive pressure of the internal explosive mixture and prevent the explosion of the surrounding explosive mixture, the shell is hard aluminum alloy, strong corrosion resistance, and the protection level is IP67. The motor is a fully enclosed squirrel cage motor, with large torque, small inertia force, insulation class F, built-in overheat protection switch, which can prevent the motor from being damaged when the electric actuator is overheated, and has a handwheel design, which can be used for operation when the power is off, to ensure safety and reliability.
