Abstract
A flow control device is disclosed. The flow control device comprises a pressure reducing valve. The pressure reducing valve comprises a valve body having at least an inlet port on a high side and an outlet port on a low side and having walls defining a regulating chamber, the outlet port in fluid communication with the regulating chamber. A diaphragm assembly is provided having a diaphragm and a stem for engaging the diaphragm. The stem has a base and a connecting arm. The diaphragm engages the main valve at a perimeter thereof so as to partially enclose the regulating chamber. A valve controlled opening cooperating with the connecting arm of the stem is located between the inlet port and the regulating chamber. The valve controlled opening is adapted to adjustably restrict flow of gas between the inlet port and the regulating chamber responsive to movement of the connecting arm.
