Features GQC series safety valves for rotary vacuum pump are electromagnetic power as a driving force, when power connected, the valve was closed so that a vacuum system and atmospheric are isolation, cut off power, in the opening of valves, atmosphere is subsequently made into the vacuum system. Valves for air and medium are applicable to the work of non-corrosive gases. Main technical performance
