Abstract

A disc-type valve is disclosed which provides a design by which the valve disc can be positively and uniformly lifted laterally off the valve seat so as to prevent abrasion of the sealing surface and/or the valve seat which might otherwise be caused by transverse movement of the valve disc in relation to the valve seat. The opening and closing movement of the valve seat is controlled by and operable in direct relation to a pivotable operating member extending through the valve body.
