A valve assembly is disclosed which allows fluid flow in a first direction and prevents fluid flow in a second, opposite direction comprising a valve housing having an upper section, a lower section and a longitudinal axis therethrough. The upper section includes an inlet end and a pair of opposite facing walls, generally equally spaced from the longitudinal axis and arranged in a diverging relationship away from the inlet end. The upper section further includes opposite facing walls, generally equally spaced from the longitudinal axis and generally perpendicular to the diverging walls. The inner surfaces of each diverging wall includes an outer perimeter and a concave surface extending inwardly from the perimeter. A flow regulator and valve support is disposed longitudinally within the upper section of the valve housing for supporting an elastomeric valve member within the upper section. The valve member comprises two mutually diverging sealing members to provide substantially linear sealing contact with the perimeter of the diverging walls of the upper section of the valve housing.

A check valve allowing fluid flow in a first direction and preventing fluid flow in a second direction comprising: a housing having an upper section and a longitudinal axis therethrough, said upper section having diverging walls; an elastomeric valve member disposed longitudinally within said upper section having two sealing members generally equally spaced and diverging generally downwardly and away from said longitudinal axis for substantially linear sealing contact with said diverging walls of said upper section; and a lower section adapted to mate with said upper section.
