ABSTRACT:
A magnetic valve for use with vacuum which has an improved junction between the stem and the valve disk which prevents detritus from impairing the seal of the valve. The valve has a magnetic drive coil outside a vacuum tight casing and an armature within the casing to which a valve stem is connected. A junction between the valve stem and the valve disk includes a head on one of the two components and a beaded margin enveloping the head on the other of the two components. An annular gasket is disposed between the head and the beaded margin.
