Product features

Electric explosion-proof ball valve is mainly composed of explosion-proof actuator and ball valve. It is an electric explosion-proof valve specially used in flammable and explosive conditions. The electrical components on the explosion-proof electric ball valve are required to be fireproof and anti-static, and all meet the explosion-proof standard. The explosion-proof grade is Exd Ⅱ BT4 (CT6), and the protection grade is IP67. The electric explosion-proof ball valve can control the valve switch by inputting the relevant power signal, and can control the ball valve operation for proportional adjustment by inputting 4-20mA signal and 220V power supply, so as to achieve automatic control of the medium flow, pressure, temperature and other parameters in the pipeline, which is widely used in natural gas, sewage, gas, coal mine, chemical and other explosion-proof occasions.
 
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 and is used for opening, closing or regulating the valve in places requiring explosion protection, such as flammable and explosive places in the chemical industry such as liquid or gas. Explosion proof valves can be divided into intrinsically safe type and flameproof type. The intrinsically safe type uses DC motor, and the explosion-proof type uses AC motor. The operator can control the valve remotely in the control room, and can also operate it on site.
