Maxitrol 325-5BL-1 Regulator

The Maxitrol 325-5BL-1 is a high-performance 1-inch NPT gas regulator engineered for 2 PSI piping systems. As a veteran-grade certified line pressure regulator, it utilizes a lever-acting design to provide responsive control from pilot flow to maximum capacity. Designed for natural gas and LP applications, the 325-5BL-1 features positive dead-end lock-up, making it essential for protecting downstream components in residential, commercial, and industrial manifolds. This unit is factory-set for a 7-11 inch w.c. outlet pressure range, supporting a max individual load of 425,000 BTU/hr and a max multiple load of 600,000 BTU/hr. To ensure longevity in harsh environments or outdoor installations, the regulator includes Imblue Technology, a proprietary coating that provides superior corrosion resistance. This Maxitrol 325 series component is a critical solution for technicians needing to reduce 2 PSI supply pressure to appliance-ready levels with precision and reliability.

Technical Benefits:

• 2 PSI Line Pressure Rating: Ideal for high-pressure gas piping systems requiring a reduction to standard appliance inches of water column.
• Imblue Coating: Enhances corrosion resistance, extending the service life of the valve body in heavy-moisture or outdoor environments.
• High Load Capacity: Supports up to 600,000 BTU/hr for multiple appliance configurations, ensuring consistent flow during peak demand.
• Dead-End Lock-Up: Provides a tight seal when there is no demand, preventing downstream pressure spikes that can damage equipment.
• Versatile Mounting: Multi-positional installation capability simplifies field retrofits and tight manifold builds.

Common Questions:

Does the 325-5BL-1 require a vent limiter?
Yes, in 2 PSI systems, local codes typically require a Maxitrol vent limiter (like the 12A39) for indoor use to eliminate the need for a dedicated vent line to the outdoors, provided it is installed in a horizontal upright position.

Can I use this regulator for propane (LP) applications?
Yes, the Maxitrol 325-5BL-1 is compatible with natural, manufactured, mixed, liquefied petroleum gases, and LP gas-air mixtures.

What is the benefit of the lever-acting design?
The leverage design allows for high seating force and accurate regulation at both high and low flow rates, which is superior to standard direct-acting regulators in 2 PSI line pressure gas applications.
