ABSTRACT:
In accordance with the present invention, a top operated tank car valve assembly includes a rod extending downwardly from the top of the tank and attached to a valve stem of a lading valve located in the bottom of the tank. A valve seat for the lading valve is located in an opening in the tank bottom and a valve cage includes circumferentially spaced openings formed in the valve cage for lading flow. A unitary valve guide, valve closure and stem retainer is provided. The unitary element includes a lower closure portion having a hub and a circumferential slot adapted to receive a closure seal. A fastener holds a seal retainer in engagement with a seal and with the closure portion. A valve guide portion extends upwardly from the valve closure at its periphery and is generally circular for a large portion of its circumference. The guide portion includes a guide portion opening on one side. A retainer portion located radially inwardly from the guide portion extends upwardly from the closure portion. The retainer portion is also circular and includes a stem opening in its center portion. This stem opening extends radially outwardly and aligns with the guide portion opening. The valve stem is inserted through the guide portion opening and the stem opening. A stem closure is provided which closes the stem opening to hold the valve stem in place.
