It is a rotary type of high-performance regulation or on-off valve class, which accepts the input and output of the current signal or voltage signal from the industrial automation control (DCS, PLC system) instrument, and can realize the proportional adjustment or two-position switch control of the fluid medium in the process pipeline, so as to achieve the automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.

Electric explosion-proof ball valve is widely used in coal chemical industry, petrochemical industry, rubber, paper making, pharmaceutical and other pipelines as a medium of diverting confluence or flow direction switching device.

The electric explosion-proof ball valve adopts the top structure, which reduces the connection bolts of the valve body itself under the condition of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the system weight on the normal operation of the valve.
