The J123 Gas Regulators from Elster are primarily used to be installed into Medium Pressure applications for high flow rates. They can regulate pressures up to 4Bar and have 3 differing models to reflect the maximum outlet pressures. The LP Version can be supplied as 50mm, 80mm or 100mm with outlet pressures up to 75mbar. Then an MP Version can be supplied for the 50mm, 80mm and 100mm connection sizes again with outlet pressure up to 350mbar. Finally a HP Version can be offered for the 50mm and 80mm sized J123s which can provide outlet pressures up to 1.035Bar.
Because of the pressures involved, it's common to use the J123 as a first stage regulator and then either a second J123 or Low Pressure Gas Regulator such as the J48 to then control the pressure from the first stage to the required outlet pressure. This ensures correct pressure control across larger pressure changes.
All of the J123 Regulators have a PN16 Flanged connection and can be used on either horizontal or vertical pipework. In order to detect the pressure of Gas coming into the regulator, an external impulse needs to be connected 15 Diameters downstream of the regulator position.
