Home My WebLink AboutPRODUCT APPROVAL325-L SERIES le4r Acting Design for 2 psi Piping Systems MI:Citrol's 325-L Series line pressure regulators are for 2 psi plpl Ill g systems. 325 Series regulators are for use on residential, com(nercial, and industrial applications. The1325 Series features a high. leverage linkage assembly to delb'�er positive dead-end lock -up. The regulators are capable of p Illlllllecise regulating control from full flow down to pilot flow. The 325-9L will be available 2Q2014. SG4 B 325-3L Pipe Sizes..................................3/8" to 2" threaded connections with NPT or ISO7-1 threads. Hou*ng Material ......................325-3L, 325-5L, 325-7AL, 325-9L; aluminum. Mounting ..................................Suitable for multi -positional mounting. If ball check vent limiting device is installed mount g P g g , in an upright position only. NOTE: All Maxitrol gas pressure regulators should be installed and operated in accordance with Maxitrol Safety Warning Instructions (see GPR_CSA_2PSI_MI_EN.FR). Certi llecations ................... ........... 325-3L, 325-5L, 325-7AL, 325-9L: ANSI Z21.80/CSA 6.22 Line Pressure Regulators. Gal pes..................................Suitable for natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas -air mixtures. Maxi um Inlet Pressure ...........2 psi (13.8 kPa) I Mini l um Inlet Pressure ............ 1 psi (6.9 kPa) Emergency Exposure Limits ....... 65 psi (450 kPa) (inlet side only) Maxi um Individual Load ........ Largest single appliance served by the regulator: 325-3 L: 140,000 Btu/h; 325-5L: 425,000 Btu/h; 325-7AL: 1,250,000 Btu/h; 325-9L: 2,250,000 Btu/h ...Total load of multi lea liance combined -ity................................. P PP 325-3L (3/8", 1/2"): 250,000 Btu/h; 325-5L (1/2"): 500,000 Btu/h; 325-5L (3/4", 1"): 600,000 Btu/h; 325-7AL (1 1/411, 1 1/2"): 1,250,000 Btu/h; 325-9L (1 1/2", 211): 2,250,000 Btu/h NOTE: Capacities are used to determine the maximum multiple appliance load. The largest single appliance served by the regulator should not exceed the maximum individual load specified above. int7emperature Ranges....-40 to 205°F (-40 to 96°C) um Regulation ................. Suitable for pilot flow applications. ©(Circle P) (0,15 CFH NG), 'T (Delta P) (0.50 CFH NG). linblej Technologyu' ................. 325-3L, 325-5L, 325-7AL, 325-9L models may be ordered with ImhlueTechnologyTm. Imblue TechnologyT1,1 increases corrosion resistance and provides extra protection against the elements for regulators used in outdoor applications.
