Abstract
A diaphragm valve is provided with a valve housing having an inlet passage extending into a chamber and an outlet passage extending from the chamber. A diaphragm is mounted to the valve housing for covering the valve chamber. The diaphragm is provided with an aperture extending centrally therethrough. A valve stem is mounted adjacent the diaphragm externally of the valve chamber, such that movement of the valve stem deflects the diaphragm. A valving element is disposed in the valve chamber and is threadedly engaged with the valve stem through the aperture in the diaphragm. A toroidal sealing bead on the valving element is sealingly engaged with portions of the diaphragm surrounding the aperture therein.
