Abstract
A check valve includes an upper housing defining an inlet of the check valve, a lower housing defining an outlet of the check valve, and a cavity interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet. The check valve further includes a valve member mounted in the cavity to selectively permit fluid flow in a first direction, and prevent fluid backflow in a second direction opposite to the first direction. The valve member includes a valve body and a valve stem portion extending axially through a central axis of the valve body.
