Abstract
To provide a railway tank car mounting flange which does not extend more than one (1) inch below the tank bottom, fixed stops to prevent rotation of the valve closure during movement between open and closed positions, and fixed stops which determine the amount of travel of the valve closure between open and closed positions are located within the tank. The valve closure is provided with outwardly extending stops which engage the fixed stops within the tank. Preferably the fixed stops extend inwardly and upwardly from the mounting flange. Preferably the valve closure is bench assembled onto a removable valve seat and is installed into the tank from the bottom, avoiding the need for a workman to be located within the tank during installation.
