ABSTRACT:
This invention relates to a valve wherein the valve disc is actively pressured onto the valve seat for a positive closure by means of a compressive force exerted on the stem which is linked to the center of the valve disc at a slanted angle. A tensile force applied to the stem disengages the valve disc from the valve seat that facilitates the opening and closing action of the valve.
