ABSTRACT:
The disclosure relates to a housing in which any one of a plurality of steam trap valve assemblies may be installed and which may be machined to accommodate a plurality of different inlet and outlet conduit configurations. The housing includes a main body through which a central cylindrical passage extends. Flanges extend radially outward from the main body at opposite ends of this passage and serve to connect the main body with the top and bottom members. The main body also includes a pair of additional passages which are parallel to the central cylindrical passage and a pair of bosses which extend radially outward. The top and bottom are made from identical castings and each comprises a circular portion adapted to mate with a flange on the main body and a boss extending diametrically from the perimeter of the flanges across at least past its center. The bosses on both the main body and the top and bottom may be machined to provide a plurality of different fluid flow paths and inlet and outlet connections. The bosses are drilled according to the particular valve assembly installed in the housing and the desired orientation of inlet and outlet connections. By using the disclosed valve housing for a number of different valve assemblies and inlet and outlet conduit configurations, the number of castings required and therefore production costs can be greatly reduced.
