Maxitrol 325-5L600-1 Regulator

The Maxitrol 325-5L600-1 is a high-performance 1 inch NPT gas regulator engineered specifically for 5 PSI piping systems. As a veteran in the field, you know that managing pounds-to-inches reduction requires a lever-acting design that ensures positive dead-end lockup and precise control even at pilot flows. This model features an integrated Over-Pressure Device (OPD), providing critical safety by limiting downstream pressure in the event of a regulator failure, making it a staple for ANSI Z21.80/CSA 6.22 certified line pressure applications. With a robust 465,000 BTU/hr max capacity, it handles high-demand natural gas and LP propane loads across residential and light commercial equipment. The durable aluminum construction and multi-poise mounting capability allow for flexible installation in tight mechanical rooms, though horizontal mounting is required when vent limiters like the 12A39 are utilized. This certified line pressure gas regulator is built for technicians who prioritize stability and code compliance.

• High Leverage Linkage: Delivers superior lockup characteristics, preventing downstream pressure spikes during appliance shutdown.
• Broad Compatibility: Suitable for natural gas, manufactured, mixed, and liquefied petroleum (LP) gas mixtures.
• Code-Compliant Safety: Factory-installed OPD 600 ensures the system meets strict safety standards for 5 PSI inlet pressure environments.
• Precision Engineering: Maintains accurate 7-11 inch wc outlet pressure even as inlet supply pressures fluctuate.
• Ease of Service: Rugged aluminum housing and simplified internal components reduce long-term maintenance requirements.

Can the 325-5L600-1 be used without a vent line?
Yes, when equipped with a factory-certified vent limiting device, this regulator can be installed indoors without the need for external vent piping, provided it is mounted in the correct orientation according to local codes.

Is this regulator suitable for small pilot loads?
Absolutely. The lever-acting design is specifically optimized to provide stable gas pressure regulation from the smallest pilot flame up to the maximum 465,000 BTU/hr capacity.

What is the difference between an OPD model and a standard 325 series?
The OPD (Over-Pressure Device) is a secondary safety mechanism required by many jurisdictions for 5 PSI systems to protect downstream equipment if the primary regulator diaphragm fails.
