Product Details
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

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.
