Maxitrol 325-11L-2 Regulator

The Maxitrol 325-11L-2 is a field-proven 2-inch NPT line pressure gas regulator specifically engineered for 2 PSI piping systems in high-demand commercial and industrial environments. This lever-acting design excels at managing substantial fuel loads, offering a 4,450,000 BTU/hr maximum capacity while maintaining precise downstream control. Certified to ANSI Z21.80/CSA 6.22 standards, this certified line pressure regulator ensures reliable positive dead-end lock-up, which is critical for protecting downstream equipment and providing stable outlet pressure from full flow down to pilot flow conditions. With a factory-set 7-11" w.c. outlet pressure range and the ability to handle a 2 PSI maximum inlet pressure, this natural gas pressure regulator is a staple for contractors installing boilers, furnaces, and large-scale water heating systems. Its heavy-duty aluminum die-cast housing is built for long-term service in rugged HVACR applications.

• High-Capacity Throughput: Handles up to 4,450,000 BTU/hr, making it ideal for large commercial manifold systems.
• Dead-End Lock-Up: The high-leverage linkage provides a positive seal when the burner shuts off, preventing pressure creep.
• Multi-Positional Mounting: Designed for flexible installation in tight mechanical rooms, though horizontal upright is recommended for specific venting configurations.
• Precise Regulation: Delivers consistent stability across 7-11 inches water column, ensuring clean combustion and efficient fuel delivery.
• Fuel Versatility: Fully compatible with natural gas, LP gas, and LP gas-air mixtures across residential and industrial sectors.

• Can this be used on 5 PSI systems? In standard configuration, this model is for 2 PSI systems. Applications exceeding 2 PSI require a certified overpressure protection device (OPD).
• Does this regulator require outdoor venting? Because the 325-11 series does not utilize a vent limiter, it must be piped to an outdoor location according to local codes.
• Is it suitable for pilot-only flow? Yes, the lever-acting mechanism allows for accurate regulation even at extremely low pilot-flow rates.
