Maxitrol 325-11L-2 1/2 Regulator
The Maxitrol 325-11L-2 1/2 is a high-capacity line pressure gas regulator specifically engineered for 2 PSI piping systems in commercial and industrial HVACR sectors. This 2 1/2" NPT lever-acting regulator manages a massive 4,450,000 BTU/hr max capacity, making it a critical component for large-scale boiler feeds or multi-appliance manifolds. Built with a robust aluminum housing, it provides a 7-11" w.c. outlet pressure range to maintain precise downstream stability. The lever-acting design ensures a positive dead-end lockup, essential for protecting equipment when downstream demand ceases. Certified under ANSI Z21.80/CSA 6.22, this unit is compatible with natural gas, LP, and mixed fuel applications. Field technicians should note that the 325-11L model requires vertical mounting for optimal performance. Whether you are dealing with high-flow burner loads or sensitive pilot flows, this Maxitrol gas regulator provides the high-leverage valve linkage required for dependable pressure reduction and consistent flow control in demanding environments.
Key Benefits- High-Flow Performance: Rated for a maximum individual load of 4,450,000 BTU/hr, supporting heavy industrial gas trains.
- Superior Lockup: Lever-acting linkage mechanism delivers a positive dead-end lockup, preventing pressure creep during off-cycles.
- Wide Compatibility: Suitable for use with natural, manufactured, mixed, liquefied petroleum gases, and LP gas-air mixtures.
- Code Compliance: CSA certified to ANSI Z21.80/CSA 6.22 standards for 2 PSI line pressure regulation.
- Precise Regulation: Accurately maintains a 7" to 11" w.c. set point from full burner demand down to pilot flow.
What is the maximum inlet pressure for the 325-11L-2?
This regulator is rated for a maximum functional inlet pressure of 2 PSI. For systems exceeding 2 PSI, a factory-assembled overpressure protection device (OPD) is required to meet code.
Can this regulator be mounted in any orientation?
Unlike smaller 325 series models, the 325-11L is designed specifically for horizontal pipe runs and must be mounted in an upright position to ensure the lever-acting mechanism functions correctly.
Does this unit include a vent limiter?
Standard 325-11L models typically require a dedicated vent line to the outdoors. If indoor venting is required, check for compatibility with specific Maxitrol vent limiting orifices based on local mechanical codes.
