JG Series pressure regulating stations for boiler


         
 


 

 


 




   Purpose
    JG Series pressure regulating stations is specially used for gas regulating stations, which includes gas-filtering measures, the regulator, the overpressure / loss pressure off safety shutoff and safety relief.The structure is usually like a tank, and covers small area , beautiful designed , suitable for families and outside installation.

    JGSerie for boiler is designed based on the most common used standards . PS:Inlet PressureP1＝0.1-0.4MPa(naturl gas ),P1=0.03-0.1MPa(coal gas );Outlet Pressure P2＝5-15Kpa.The user can choose the stations according to different heat value (natule gas and coal gas).
