Abstract: A check valve assembly includes a body, a valve assembly configured to engage a port of the check valve assembly, and a handle integrally formed with the body and extending from a substantially cylindrical exterior surface thereof. The handle includes a first vertical support member having a first interior surface, a second vertical support member having a second interior surface, and a horizontal support member that has a third interior surface and extends between the first and second vertical support members. The first, second, and third internal surfaces, and the exterior surface of the body member, define a handle aperture. The first and second interior surfaces of the handle aperture are configured to accommodate first and second bolts of a pipe flange fitting extending through the handle aperture.
