Electric explosion-proof ball functions and advantages of pneumatic valve
by:AIRWOLF2021-01-15
the application of electric explosion-proof ball pneumatic valve electric explosion-proof ball pneumatic valve structure with Jane, switching rapidly, large flow capacity, the characteristics of zero leakage, suitable for high viscosity, containing the occasion of fibers, solid particles and fluid.
Electric explosion-proof ball pneumatic valve is widely used in petroleum chemical industry, metallurgy, light industry and other industrial control fields or cut off to the medium inside the pipeline gas, liquid circulation.
the function of electric explosion-proof ball pneumatic valve electric explosion-proof ball pneumatic valve explosion-proof grade for Exd Ⅱ BT, protection grade for IP, field control devices.
Explosion-proof electric pneumatic valve ball main characteristic is: not electricity, throw the clutch handle manual operation can be performed.
Electricity, automatic reset of the clutch.
Flow can be arbitrary, adjustable range, can be used for high pressure and large diameter, high viscosity control, with fibrous and fine particles of medium.
electric explosion-proof ball pneumatic valve pneumatic valve has electric explosion-proof ball quarter-turn explosion-proof electric actuators, and pneumatic ball valve ball, is by the electronic quarter-turn actuators R or HQ series and pneumatic ball valve regulating mechanism.
