Valve Assembly

A valve assembly comprising:

• a valve housing having a lower end and an upper end, and defining an inner bore, the valve housing including a valve seat spaced apart from the lower end and the upper end, separating the valve housing into a first valve side and a second valve side, the valve seat defining a seat surface that is inclined inwardly and toward the lower end of the valve housing;
• a valve body including an outer rim with an outer surface and a central web spanning therebetween, the outer rim including at least two spaced apart outwardly directed annular flanges defining at least one channel therebetween, and a seal positioned within the at least one channel, the outer rim inclined outwardly so as to correspond to the seat surface, with the valve body further having an axis of rotation that extends transversely through the valve body spaced apart from the annular flanges,
• the valve body being positioned within the inner bore of the valve housing, and pivotably coupled to the valve body along an axis of rotation that is positioned between the valve seat and the upper end of the valve housing, the valve body being positioned in a first closed orientation wherein the outer rim corresponds to the seat surface with the seal sealing the first valve side from the second valve side, and a second open orientation wherein the outer rim is pivoted away from the seat surface providing fluid communication between the first valve side and the second valve side, wherein, in the first closed orientation, the valve body is structurally configured to be translatable toward the lower end, thereby directing the outer rim toward the seat surface.
