GUD-A series


Electric vacuum (pressure) ball valve

GUD-A series electric vacuum (pressure) ball valve adopts rotary electric and electronic regulating valve driving device, which can realize valve opening and closing by switching external power supply (manual index switch or computer control) or external input signal Or the control of the middle position, so as to achieve the purpose of turning on or cutting off the air flow in the vacuum pipeline. The valve is straight-through and sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed in any position. The applicable working medium is gas or liquid with acid and alkali.
