ABSTRACT:
A check valve including a housing formed by a base portion and a cap portion positioned in telescoping relation with each other. A disc shaped valve member is positioned within the housing and is defined by opposing first and second planar sides. The valve member includes a spherical portion located centrally thereon and which is captured between first and second valve supports supported on the base portion and cap portion, respectively. The valve supports hold the valve member in engagement with a valve seat, and the valve member moves out of engagement with the valve seat in response to a fluid pressure applied at a fluid inlet in the base portion to permit forward fluid flow while preventing fluid flow in the reverse direction.
