                     A bimetallic steam trap, shown in Figure 15-4,  operates on the same principle as a
                     residential-heating thermostat. A bimetallic strip, or wafer, connected to a valve disk
                      bends or distorts when  subjected to  a change in  temperature. When  properly  cali-
