Maxitrol 325-3BL-1/2 Regulator

The Maxitrol 325-3BL-1/2 is a professional-grade certified line pressure gas regulator engineered for precision fuel management in high-efficiency heating systems. Designed specifically for 2 PSI piping systems, this 1/2" NPT gas regulator utilizes a lever-acting design to maintain a stable 7-11" WC outlet pressure regardless of fluctuations in the inlet supply. It is rated for a maximum inlet pressure of 2 PSI and features a positive dead-end lock-up (PDEL) capability, which is critical for preventing downstream over-pressurization during periods of zero flow. Built with Imblue Technology, the internal components offer superior corrosion resistance, making it an ideal choice for both natural gas and propane (LP) applications. With a maximum individual load of 140,000 BTU/hr and a maximum multiple load of 250,000 BTU/hr, this Maxitrol 325 series component ensures reliable flow regulation for residential and light commercial appliance manifolds.

Technical Benefits for Contractors:

• Precise Pressure Regulation: The lever-acting mechanism provides a high stroke-to-diaphragm ratio, ensuring accurate control of 7-11" WC outlet pressure.
• Enhanced Safety Standards: Features positive dead-end lock-up to ensure a tight shut-off when appliances are not in operation.
• Durable Construction: Integrated Imblue Technology provides a protective coating that resists moisture and corrosive elements in the gas stream.
• Versatile Installation: Standard 1/2" NPT connections allow for seamless integration into existing 2 PSI gas piping systems.
• High Capacity Throughput: Supports 140,000 BTU/hr individual loads, accommodating high-demand gas-fired equipment.

Common Contractor Questions:

Can the Maxitrol 325-3BL-1/2 be installed outdoors?
Yes, provided it is installed in a vertical position with a proper vent protector to prevent debris and moisture from entering the atmospheric vent.

Is this regulator compatible with both Natural Gas and Propane?
This gas pressure regulator is certified for use with both fuel types, provided the 7-11" WC spring range matches the appliance manifold requirements.

What does the 'BL' designation signify in the part number?
The 'BL' indicates it is a certified line pressure regulator for up to 2 PSI, specifically equipped with Imblue Technology for enhanced component longevity.
