Abstract
In accordance with the present invention a tank car bottom outlet mounting flange is provided with a stepped valve seat slot to receive a contained valve seat member. The valve seat is provided with an upper internal valve seat portion to receive a valve closure. A valve seat body portion located below the valve seat portion is provided with a valve seat slot to receive an operator retainer to prevent the operator from moving vertically during operation. A valve seat flange portion extends radially outwardly from the valve seat body portion and is provided with first fastener openings for holding the valve seat member in place within the mounting flange and supporting the valve closure and any lading in the tank. The valve seat flange portion is provided with second fastener openings, preferably circumferentially spaced from the first fastener openings to receive fasteners to hold in place an outlet chamber extending below the valve seat member. Preferably an outlet chamber flange portion receives the second fasteners and also at least partially supports the operator retainer with the valve closure.
