Abstract
A top-loaded rotary valve with elliptical sealing is provided. The valve includes a valve cartridge with a lower cylinder portion having a first flow opening, an upper cylinder portion having a second flow opening, a rotor, and a gasket positioned between respective ends of the lower cylinder portion and the upper cylinder portion. The rotor includes a stem and a disc configured to rotate within the cartridge. The lower cylinder portion and the upper cylinder portion are mated to the gasket along a plane that defines an ellipse along the respective cylinder ends. The disc has perimeter that is similar to the ellipse, and the rotor rotates between a closed position in which the elliptical perimeter of the disc is coincident with the gasket to prevent flow between the flow openings and an open position that permits flow between the flow openings.
