ABSTRACT:
An improved pneumatic outlet (10) is for use on a railcar (C) for discharging a lading from a hopper (H) of the railcar. The outlet comprises an integrally formed bottom cover (12) extending the length of the outlet. A pair of outlet valves (50A, 50B) are installed in the cover. The valves are mounted on respective valve shafts (54A, 54B) and are installed in the cover in a diagonal arrangement. Accordingly, each valve allows discharge of lading from one side of the hopper. A bulkhead (40) is also installable in the cover and supports an inner end of the respective valve shafts. The cover is severable into two sections (36A, 36B). One of the sections is reversible with respect to the other section. Thereafter, the two sections are joined together to form a unified cover through which lading flows during discharge. The bulkhead fits within the reunified cover such that no gaps or other deformities are present which would collect material that may contaminate a lading.
