Abstract
A check valve is provided that includes a valve body, a stop bar, a flapper, and a protrusion. The valve body has a flow channel extending therethrough, a first stop support, and a second stop support. The first and second stop supports extend axially from the valve body. The stop bar is coupled to and extends between the first and the second stop supports. The flapper is rotationally mounted to the valve body and comprises a first material. The protrusion is integrally molded with the flapper and extends axially therefrom. The protrusion comprises a second material that is non-metallic and different than the first material. The flapper is moveable between a closed position, in which the flapper at least substantially seals the flow channel, and a fully-open position, in which the protrusion contacts the stop bar and the flapper unseals the flow channel.
