ABSTRACT:
High pressure natural gas enters the regulator at the inlet port and is directed through a filter to a passage in the valve body and into the inner chamber of the valve body. The valve means which controls the high pressure gas as it expands past a valve seat and into the low pressure chamber of the regulator body, is spring mounted in a bushing to prevent undesired vibrations. The expanded and colder low pressure natural gas is directed through a nozzle to the outlet port of the regulator body. The outlet port has a bypass orifice that leads to the diaphragm chamber. Pressure variations in the diaphragm chamber control the movement of the valve means coupled to the diaphragm means.
