Abstract
A check valve including a clevis, a hinge pin, a hinge configured to be rotatably coupled to the clevis by the hinge pin, and a disc configured to be detachably coupled to the hinge. The hinge includes a first hinge member having a male interlocking feature and a second hinge member defining a female interlocking feature corresponding to the male interlocking feature. The second hinge member is configured to be detachably coupled to the first hinge member. When the first hinge member is coupled to the second hinge member, the male interlocking feature of the first hinge member is received in the female interlocking feature defined in the second hinge member to prevent angular separation of the first and second hinge members about the hinge pin. The first and second hinge members may define a non-circular opening configured to prevent rotation of the disc relative to the hinge.
