Gas Pressure Regulator GDJ

Gas Pressure Regulator GDJ

Product catalog summary

Overview: The GDJ gas pressure regulator is a universal device designed for gaseous media, ensuring high control accuracy with an inlet pressure compensation diaphragm. It is EC type-tested and certified, requiring no breather line due to its internal impulse and additional safety diaphragm.

Application: The GDJ regulator maintains constant outlet pressure despite varying gas flow rates and inlet pressures, suitable for gas burners and appliances in industrial and heating sectors. It is particularly used in applications like bogie hearth and roller hearth furnaces.

Type Code: The GDJ series includes various nominal sizes (15, 20, 25, 40, 50) and configurations, such as internal thread types (Rp, NPT) and pressure test point options.

Technical Data:

Gas Types: Suitable for natural gas, town gas, LPG, and biologically produced methane (max. 0.02% H2S). The medium must be dry and free of condensate.
Inlet Pressure: Up to 400 mbar (5.8 psig).
Outlet Pressure Ranges: GDJ 15: 2 to 55 mbar; GDJ 20-40: 5 to 160 mbar; GDJ 50: 5 to 100 mbar.
Control Range: 10:1.
Temperature: Ambient -20 to +60°C; Storage -20 to +40°C.
Materials: Valve housing and seat are aluminium; valve disc is plastic with a Perbunan seal; diaphragms are also Perbunan.
Special Version: Available for air use.
Thread Standard: Rp to ISO 7-1.

Maintenance: The regulator requires maintenance at least once a year, or twice a year if used with biologically produced methane.

Flow rate Application Code 1 Not for T-product. 2) If “none”, this letter is omitted. The spring-loaded gas pressure regulator GDJ with inlet pressure compensation diaphragm and zero shut-off serves to maintain the set outlet pressure constant despite changing gas flow rates and inlet pressures in gas pipelines. Thanks to an additional safety diaphragm, no breather line is required. For controlling the pressure of the gas and air supply to gas burners and gas appliances in industry and the heating sector.
