Jan 07, 2003 · A pressure regulator is a feedback control mechanism designed to maintain a constant downstream pressure through the manipulation of gas flow. By definition, a regulator is composed of three essential components (see Figure 1 illustration): 1. Restricting Element — A restriction which allows

- Every pressure regulator is designed to operate at a minimum and maximum inlet pressure and a predetermined flow range. A regulator performance curve illustrates how the pressure regulator will perform at this range of inlet pressure and flows. Each model will have a different performance curve. The Y-axis shows outlet pressure, and the X-

pressure regulator provides the same function. Pressure regulators reduce a supply (or inlet) pressure to a lower outlet pressure and work to maintain this outlet pressure despite luctuations in the inlet pressure. The reduction of the inlet pressure to a lower outlet pressure is the key characteristic of pressure regulators.

the low-pressure chamber. In a single-stage regulator, delivery pressure increases as cylinder pressure decays, because there is less gas pressure exerted on the valve stem. Thus, fre-quent adjustment of the control knob is required to maintain constant delivery pressure. This does not pose a problem, however, with pipelines and liquefied
