Maxitrol 325-5L600-1-LIM Regulator

The Maxitrol 325-5L600-1-LIM is a high-performance 1" NPT gas regulator designed for rigorous line pressure applications. Engineered as a lever acting design with OPD (Over-Pressure Device), this ANSI Z21.80/CSA 6.22 certified valve serves as a critical 2-PSI or 5-PSI piping system interface, reducing upstream pressure to safe operating levels for downstream equipment. It handles 5 PSI max inlet pressure for Natural Gas and 2 PSI max inlet pressure for LP gas with a precise 7-11"wc outlet pressure range. With a 465,000 BTU/hr max capacity, it secures consistent flow for high-demand appliances. The factory-installed vent limiters enable indoor installation without the need for additional vent piping to the outdoors, provided the unit is mounted in the recommended horizontal upright position. This Maxitrol gas pressure regulator ensures positive dead-end lockup, preventing downstream pressure spikes that can damage sensitive appliance valves.

• Code Compliance: Full ANSI Z21.80/CSA 6.22 certification for use in residential and commercial 5-PSI gas systems.
• Enhanced Safety: Integrated Over-Pressure Device (OPD) provides mandatory protection against downstream over-pressurization.
• Vertical Integration: Factory-included vent limiters reduce labor by eliminating the requirement for external vent lines.
• Versatile Application: Validated for both Natural Gas and Propane (LP), supporting a wide range of heating and industrial equipment.
• Precision Control: Lever-acting linkage ensures stable outlet pressure regulation from full flow down to pilot stages.

Can this regulator be used for outdoor installations?
Standard models are designed for indoor use with vent limiters. For outdoor applications exposed to elements, an Imblue technology coating and a vent protector are required.

What is the proper mounting orientation for this model?
When utilizing the vent limiters, the regulator must be installed in a horizontal, upright position to ensure the ball-check safety mechanism functions correctly.

Does this unit replace the regulator on my furnace or boiler?
No, this is a line pressure gas regulator typically installed upstream of the equipment. It reduces system-wide pressure to the 7-11"wc range required by the appliance’s own internal regulator.
