Type FL Operational Schematic TYPE FL TYPE S/2: V - SENSING PORT R - PILOT SUPPLY PORT M - INLET PORT Introduction The FL Series of axial flow appliances was designed to meet a wide range of application. FL Series regulators are used in reduction, distribution, and conveying stations of suitably filtered natural gas. They can also be used for air, propane, butane, LPG, city gas, nitrogen, carbon dioxide, and hydrogen. The Monitor regulator is used as an emergency device in gas pressure reduction systems. The purpose of this device is to protect the system against the possible overpressure, while keeping the reduction line in service. The monitor controls downstream pressure at the same point as the main regulator and is set a little higher than the latter. Under normal duty, the monitor is fully open as it detects a pressure value lower than its set value. If, due to any active regulator fault, downstream pressure increases, when it exceeds the tolerated level, the monitor comes into operation and adjusts pressure to its own set value. special reactive built-in silencer, Type SR, can be fitted near the FL Series regulator shutter which is highly efficient up to a theoretical speed of 80 m/s / 262 ft/s calculated at the outlet flange. The noise reduction is up to 20 db(). Type SRS silencer consists of a Type SR silencer plus a widened outlet flange in which a second silencer can be fitted. The second silencer has an initial multi-path section and a second multi-stage section. Noise reduction reaches 28 db() without limiting the velocity in the outlet flange. STP which is habitually used downstream of Type SRS silencers but can also be combined with the Type SR silencer, produces a further noise reduction by 10 to 20 db(). Overall reduction in noise level is the sum of the reduction produced by Type SR or SRS plus the STP induced reduction. This type of silence prevents noise propagation along the piping. 3
