VACUUM VALVE FOR PROVIDING A SYMMETRICAL FLUID FLOW

Abstract: a regulating vacuum valve has a first valve seat having a first valve opening defining a first opening axis and a first sealing surface surrounding the first valve opening, and a first valve disk having a first contact surface corresponding to the first sealing surface. the valve includes a drive unit coupled to the first valve disk to adjust at least between an open position to a closed position. the regulating vacuum valve has at least one second valve seat, having a second valve opening with a second sealing surface. in addition, a second valve disk having a second contact surface corresponding to the second sealing surface is provided. an overall valve opening of the regulating vacuum valve is formed by the first valve opening as a first valve partial opening and the second valve opening as a second valve partial opening.
