Gas Pressure Regulator RMG 502

Product information

serving the gas industry worldwide

Gas Pressure regulator rmg 502 Application, Characteristics, Technical Data

Application • for offtake stations in gas transmission systems, for gas supply to industrial and power plants • suitable for natural gas and all non-corrosive gaseous media Characteristics

2

• large inlet pressure range • special diaphragm system as regulating valve device, therefore small number of internal parts • easy maintenance, low noise level • outlet pipe diameter is four times the diameter of inlet size (2.25 times at DN 200/300) Technical Data 100 bar

max. inlet pressure pumax

pilot RMG 630 - two stage version, higher regulating accuracy (lower AC) pilot RMG 632 - two stage version for inlet pressure regulation outlet pressure ranges Wd 0,3 to 40 bar (with diaphragm assembly) Wd 20 to 90 bar (with metal harmonica type measuring unit)

pilot RMG 635 - three stage version with automatic load limiting stage, pdmin and electropneumatic control stage pilot RMG 638 - four stage version, with automatic load limiting stage, pdmin-stage, pdmaxstage and electro-pneumatic control stage pilot RMG 640 - one stage version, application up to 15 bar ∆p (inlet pressure) pilot RMG 642 - one stage version für inlet pressure regulation
