China [CN] Explosion-proof electric ball valve overview:
The electric explosion-proof ball valve is mainly composed of an explosion-proof actuator and a ball valve. It is an electric explosion-proof valve used in flammable and explosive conditions. The electrical components on the explosion-proof electric ball valve are required to be fire-proof and anti-static, and all meet the explosion-proof standards. The explosion-proof grade is ExdIIBT4 (CT6), and the protection grade is IP87. The electric explosion-proof ball valve can control the valve switch by inputting the relevant power signal, and can control the operation of the ball valve by inputting the 4-20mA signal and 220/power supply for proportional adjustment, so as to achieve the automatic control of the medium flow, pressure, temperature and other parameters in the pipeline. Applied to explosion-proof occasions such as natural gas, sewage, gas, coal mine, chemical industry, etc. EXDIICT4 grade explosion-proof electric ball valve
Explosion-proof electric ball valve features:
Explosion-proof Shendong modified valve means that the curved heat actuator of the ball valve h meets the explosion-proof standard. It is used in places requiring explosion-proof, such as liquid or gas (inflammable and explosive places in the chemical industry, used to open and close the valve. Or section, explosion-proof valves can be divided into intrinsically safe type and explosion-proof type. The intrinsically safe type uses a DC motor, and the explosion-proof type uses an AC motor. control, and can also be operated on site.
