RTJ-※/※NHQ(NH) Series/Indirect-action Mode Pressure Regulator for Gas
       
 

2 Application
RTJ-※/※N Series indirect-action mode pressure regulator for gas is used for high middle-pressure, middle middle-pressure first class gas transmission and distribution system, It can be used as district regulators or for industry and commerce users as well as direct-fired equipments. It is applicable for natural gas, artificial coal gas and liquefied petroleum gas（LPG）.
It accords with the standard CJ274-2008 “City Gas Pressure Regulators”.
(NH was not equipped with shut-off valves, NHQ was equipped with shut-off valves)
