JG Series pressure regulating stations for boiler

DATE:2014-01-14 | comments: | posted by:liuailin

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.

JG Series for boiler is designed based on the most common used standards . PS:Inlet Pressure P1=1 ~ 4bar(natural gas ), P1=0.3 ~ 1bar (coal gas ); Outlet Pressure P2=0.05 ~0.15bar.The user can choose the stations according to different heat value (natural gas and coal gas).
