Gud series electric vacuum (pressure) ball valve adopts rotary electric and electronic regulating valve driving device, which can realize the control of valve opening, closing or middle position through the switch of external power supply (controlled by manual position switch or computer) or external input signal, so as to connect or cut off the air flow in vacuum pipeline. The valve is straight through type, sealed by spherical surface, so it can be used in vacuum state or low pressure state, and can be installed at any position.
Applicable working medium is acid and alkaline gas or liquid.
