The electric explosion-proof ball valve primarily consists of an explosion-proof actuator combined with a ball valve, serving as a specialized electric explosion-proof valve designed for flammable and explosive environments. All electrical components on the explosion-proof electric ball valve undergo fireproofing and anti-static treatment, meeting explosion-proof standards with a rating of ExdⅡBT4(CT6) and an IP67 protection rating. The electric explosion-proof ball valve can be controlled to open or close by inputting relevant power signals. Inputting a 4-20mA signal and 220V power supply enables proportional regulation of the ball valve's operation, achieving automated control of parameters such as flow rate, pressure, and temperature of the medium within the pipeline. It is applied in explosion-proof environments including natural gas, sewage, gas, coal mining, and chemical industries.
