325 Series pounds to inches regulators are for use on residential, commercial, and industrial applications. The 325 Series features a high leverage valve linkage assembly to deliver positive dead-end lock-up. The regulators are capable of precise regulating control from full flow down to pilot flow.
SPECIFICATIONS Gases Suitable for natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas-air mixtures.
Maximum Individual Load Largest single appliance served by the regulator.
325-3(B)L: 140,000 Btu/hr
Capacity Total load of multiple appliances combined. 325-3(B)L (3/8”, 1/2”): 250,000 Btu/hr
Ambient Temperature Limits All Models: -40ºF to 205ºF (-40ºC to 96ºC)
Vent Pipe Connections 325-3(B)L: 1/8” NPT
Maximum Inlet Pressure 2 psi (13.8 kPa)
Minimum Inlet Pressure CSA Certified.: 1 psi (7 kPa)
Outlet Pressure Range Certified Spring: 7 - 11” w.c.
Emergency Exposure Limits All Models (Inlet Side Only): 65 psi (450 kPa)
NOTICE These regulators provide no downstream over-pressure protection in the event of failure. At supply pressures in excess of 2 psi, they should not be used. For Technical Support contact a Maxitrol Technical Support Representative. See Maxitrol Safety Warning Instructions, GPR_CSA_2PSI_MI_EN.FR
Mounting Position The 325 Series is suitable for multi-poise mounting, but when used with a vent limiting device, the regulator must be mounted in a horizontal upright position (see Figure 2). Install the regulator properly with gas flowing as indicated by the arrow on the casting. (See Maxitrol Safety Warning Instructions, GPR_CSA_2PSI_MI_EN.FR).
