Maxitrol 325-3L-1/2 Regulator

The Maxitrol 325-3L-1/2 Gas Regulator is a job-site standard for line pressure regulation in both residential and commercial gas piping systems. This 1/2" NPT certified regulator is specifically engineered to reduce 2 PSI gas systems down to appliance-level pressures. Utilizing a lever-acting design, it provides high-precision control and a positive dead-end lock-up, ensuring gas flow stops completely when the downstream appliance demand ceases. With a maximum individual load capacity of 140,000 BTU/hr and a multiple load capacity of 250,000 BTU/hr, this unit is optimized for natural gas and propane applications involving furnaces, high-efficiency boilers, and water heaters.

Key Benefits for Contractors:

• System Compatibility: Seamlessly integrates into 2 PSI piping systems using standard 1/2" NPT connections.
• Precise Regulation: The 7-11" W.C. outlet pressure range allows for fine-tuning based on specific manifold requirements.
• Enhanced Safety: Positive dead-end lock-up prevents downstream over-pressurization during the off-cycle.
• Versatile Mounting: Suitable for multi-appliance configurations or dedicated individual equipment loads.
• Field Proven: The Maxitrol 325 Series is the industry benchmark for reliable gas pressure control and long-term durability.

Common Questions:

Does this regulator require a vent limiter?
This specific model does not include a vent limiter. For indoor installations, local codes often require a vent line to be piped to the outdoors, or the installation of a certified 12A09, 12A39, or 12A49 vent limiting device, depending on the orientation.

Can this be used for outdoor installations?
Yes, the Maxitrol 325-3L-1/2 can be installed outdoors; however, it must be protected from the elements and the vent port must be positioned to prevent the entry of water, ice, or debris.

Is this compatible with both Propane (LP) and Natural Gas?
Yes, it is high-performance certified for both natural gas and LP applications, provided the inlet pressure does not exceed 2 PSI.
