Maxitrol 325-7AL210D-1 1/2L Regulator

The Maxitrol 325-7AL210D-1 1/2L is a high-capacity line pressure gas regulator designed for sophisticated downstream applications requiring precise pressure control. Engineered with a lever-acting design and an integrated Overpressure Protection Device (OPD), this unit manages a 1-1/2" NPT connection with a maximum flow rate of 1,250,000 BTU/hr. It supports a 5 PSI max inlet pressure for natural gas and 2 PSI for LP gas, providing a stable 7-11" WC outlet pressure range. The factory-installed vent limiter eliminates the need for additional vent piping to the outdoors, streamlining HVAC installation and reducing material costs. Designed for multi-family residential or commercial systems, this Maxitrol 325 series regulator ensures stable lock-up and consistent performance for high-demand appliances, maintaining safety and efficiency in complex piping runs.

• OPD Integration: Provides redundant safety through an internal mechanism that limits downstream pressure in the event of primary regulation failure.
• High-Flow Capacity: Supports up to 1.25 million BTUs, making it ideal for large boilers, rooftop units, and commercial kitchen manifolds.
• Vent Limiting Technology: Allows for indoor installation without venting to the atmosphere, provided local codes are met.
• Precision Control: Maintains steady outlet pressure across varying inlet surges, preventing pilot outages and equipment malfunctions.

Common Questions

Can the Maxitrol 325-7AL210D be mounted in any orientation?
For proper performance and to utilize the vent limiter, it must be mounted in an upright, horizontal position. Vertical installation may affect the calibration and safety rating.

Does this regulator require a separate vent line?
Since this model includes a certified vent limiter, it is technically vent-less for indoor use; however, always verify with local mechanical codes and AHJ requirements.

What is the lock-up pressure rating for this model?
The 325 series is rated for high-quality lock-up performance, meaning it tightly controls pressure spikes when there is zero flow, protecting downstream valves.
