RX-※/0.4-Q Series Gas Regulator
       
 

2 Application
RX-※/0.4-Q series wall-mounted regulator was applied to low-pressure first class as transmission and distribution system for buildings or public service users. 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”.

  
       
       
 

2 Main Technical Parameters
Inlet Pressure Rank(P1): 0.05～0.4MPa
Outlet Pressure Rank(P2): 15KPa
1～15KPa(80Q)
Pressure Precision Grade: AC5
Shut Off Pressure Grade: SG10
Working Temperature(t): -20～60℃
Caliber: DN25, DN40, DN50, DN80 (Type QJ only provides DN25)
Attended Mode
RX-25/0.4-QJ: Inlet/outlet Flange: PN1.6MPa, DN25
RX-25/0.4-Q: Inlet/outlet Flange: PN1.6MPa, DN25
RX-40/0.4-Q: Inlet/outlet Flange: PN1.6MPa, DN40
RX-50/0.4-Q: Inlet/outlet Flange: PN1.6MPa, DN50
RX-80/0.4-Q: Inlet Flange: PN1.6MPa, DN50
Outlet Flange: PN1.6 MPa, DN80

2 Features
★ Built-in filter makes the more reliable regulator;
★ Built-in safety shut-off valve makes it able to cut off the gas source in time when the downstream pressure become excessive for accident;
★ Built-in safety bleeding valve will partially discharge the gas to avoid frequent startup of the shut-off valve because of the elevated back-pressure for non-malfunction problem (downstream valve close fast or temperature change etc.);
★ Modular in structure, easy in installation and convenient in maintenance;
★ Two types of the main regulator: vertical or horizontal
★ Two types of outer box: Stainless steel or static spray outer box
