A check valve comprises a valve housing defining a pair of valve openings, a pair of mounting posts arranged on opposed sides of the valve housing, a hinge pin mounted between said mounting posts, a pair of flapper elements pivotably mounted to the one or more hinge pins for rotation relative to the housing between an open position in which they permit fluid flow through the respective valve openings and a closed position in which they prevent fluid flow through the valve openings. A pair of elastically deformable leaf spring stop elements, each of which comprise respective end portions that are mounted to, and extend upwardly from, said mounting posts and a stop portion arching upwardly from, and extending between said end portions, such that each flapper element will engage a respective surface of said stop portion when in the open position.
