Abstract

A novel spatial arrangement of valve ports and hold-down bolt holes in the body of an exhaust gas recirculation valve, wherein the centers of the ports are between and aligned with the centers of the bolt holes, thereby producing maximum sealing force around the ports against the surface to which the valve is bolted, such as the exhaust and intake manifolds of an internal combustion engine.
