Maxitrol 325-5L-1/2 Regulator

The Maxitrol 325-5L-1/2 is a precision-engineered line pressure gas regulator designed for high-performance piping systems. This 1/2" NPT regulator features a lever acting design, ensuring a stable 7-11"wc outlet pressure range even when service pressures fluctuate. Built for positive dead-end lock-up, it is an essential component for protecting downstream equipment in residential, commercial, and industrial gas applications. With a 2 PSI maximum inlet pressure, this certified gas regulator handles a 425,000 BTU/hr max individual load and up to 500,000 BTU/hr total load for multiple appliances. Its rugged construction and CSA certification make it the industry standard for 2 PSI piping systems, providing the reliability required for multi-family dwellings and commercial kitchens where gas flow consistency is critical for safety and efficiency.

• Dead-End Lock-Up: Ensures zero pressure leakage to downstream components during the off-cycle.
• High Flow Capacity: Supports up to 500,000 BTU/hr capacity, making it suitable for high-demand boiler and water heater installs.
• Field-Proven Reliability: The lever acting mechanism provides superior control and response compared to standard spring-loaded regulators.
• Multi-Appliance Versatility: Ideal for natural gas and LP applications requiring precise pressure reduction from 2 PSI lines.

Can the Maxitrol 325-5L be installed outdoors?
Yes, provided it is installed with a certified vent protector and mounted in an upright position to prevent moisture accumulation in the vent line.

What is the purpose of the 325-5L over the standard 325-3?
The Maxitrol 325-5L series offers a higher flow rate and larger physical port size, specifically designed for higher BTU loads that smaller regulators cannot handle without excessive pressure drop.

Does this regulator require an external vent limiter?
While internal vent limiting options exist, local codes usually require a dedicated vent line to the outdoors or a specific 12A09, 12A39, or 12A49 vent limiter for indoor installations.
