ABSTRACT:
A pipeline swing check valve comprising a fabricated valve body with a fabricated cylindrical hub member welded therein. The clapper is hinged, not to the body, but directly to the hub member or some part thereon so that it can be mounted and adjusted for proper seating without handling the entire valve, and then installed with the hub member as a unit.
