ABSTRACT:
An axially shiftable gas control and shut-off valve utilizing a spherical ball check seatable in a frusto-conical valve seat formed along a gas flow path in a valve body member, and a valve stem extending transversely through the body member across the flow path and axially shiftable with respect thereto along an axis perpendicular to the axis of symmetry of the valve seat. The valve stem has a concentrically-arranged, frusto-conical cam portion operative, when the valve stem member is shifted between one position and another, to move the ball check between seated and unseated positions with respect to the valve seat to control gas flow.
