6 A-0 A-05 When the regulator is in operation, the inlet pressure (FI) plus the out pressure (Fo) should be equal to the downward force on the diaphragm by the compressed spring (Fs), namely FI+Fo=Fs to reach an equilibrium. When the outlet pressure (Fo) is lower than the set pressure, the poppet would be pushed away from the seat by the excess downward force, allowing more high pressure gas to enter the chamber thus to increase the outlet pressure. As soon as the outlet pressure (Fo) exceeds the set pressure, the excess upstream force shall lift the poppet back to the seat to prevent the gas from entering. Fo Fs FI Fo Fs FI Fo Fs iston Regulator Although diaphragm regulators have many advantages such as its precision, sealing effect, cleanliness and etc., in order to ensure its sensitivity, the structural strength of the diaphragm regulators is low so as not being able to withstand high pressure. Therefore, it is recommended to utilize the piston regulators for high pressure applications. A piston regulator has the same working principle as a diaphragm regulator. The key distinction is that the diaphragm is changed to a piston to satisfy the needs for high pressure applications. The inlet pressure of a piston regulator can reach 60 psig. Its construction is simple and reliable with multiple options of O-ring to fulfill the various requirements of different media. iston Fs > Fo+FI Dual-stage Diaphragm Regulators When the inlet pressure (FI) decreases, the outlet pressure (Fo) shall increase. Even if this increasement may not be significant, The dual-stage regulator may be a better option when more stable pressure required, and the upstream pressure fluctuates violently. Fs < Fo+FI (in this figure, inlet pressure doesn't act on diaphragm) Series of Cylinder ressure Regulators (FCR) Cylinder regulators are designed to reduce the pressure of the cylinders to lower levels. The regulator is connected to the cylinder mostly through a cylinder connection. ine ressure Regulators (FR) The function of a dual-stage regulator is similar to that of two single-stage regulators in series. The st-stage regulator would reduce the inlet pressure to an intermediate level for the ndstage regulator to adjust to a constant output, which at the most extent ensures the stability of the outlet pressure. Interstage ressure 90 From View ine pressure regulators are used to further control the pressure in line. ressure Control anels (FSR) ressure control panels are installed in the gas storage area (cylinder stock room or gas cabinet). They reduce cylinder or tank pressure to the desired line pressure for in-house use. Via the subsequent piping system the gas will be guided to the point-of-use. o ressure M I I Changeover System(FDR) Manual changeover system can connect with several independent gas sources at a time. When one gas source is depleted, it could be switched to other source quickly through a shut-off valve. Automatic changeover system is installed onto gas pipelines which need continuous gas supply. It can connect with two independent gas sources at a time. When gas source from one side is depleted, it can automatically switch to the gas source from the other side. Subsequently, replace the exhausted gas source. oint-of-use anels (FR) M Its function is to most precisely regulate the pressure and shut off at the point-of-use. o Time

Consequently, the diaphragm of side A regulator is off from the stem to close the regulator..automatically change to another side when gas source of one side is depleted.

Meanwhile, gas from side A shall flow back into side. At this moment, before replacing new gas source of side, the diaphragm valve should be first turned off, with the vent valve open to exhaust remaining pressure.

However, its function is to control the upstream pressure, while the purpose of the latter is to control its downstream. When the system pressure is lower than the set pressure, the regulator is shut off to obstruct the flow;. 98 (50.) When the system pressure is higher than the set pressure, the diaphragm compresses the inner spring so as to allow the medium flowing through to exhaust the excess pressure of the system. ottom View ottom anel Cut-out (.) 0.
