  • DESCRIPTION

    Features of explosion-proof electric ball valve:

     

    Explosion-proof electric ball valve means that the electric actuator on the ball valve meets the explosion-proof standard. It is used in occasions that require explosion-proof, such as flammable and explosive places in the chemical industry such as liquids or gases. It is used to open, close or adjust the valve. Explosion-proof valves can be divided into two types: intrinsically safe and explosion-proof. The intrinsically safe type uses a DC motor, and the explosion-proof type uses an AC motor. The operator can control the valve remotely in the control room or on site. Perform operations.
