Maxitrol 325-7ABL210D-1 1/4 Regulator

The Maxitrol 325-7ABL210D-1 1/4 is a line pressure gas regulator engineered for high-performance service in commercial and industrial piping systems. Featuring a 1 1/4" NPT connection and a lever acting design with OPD (Overpressure Protection Device), this regulator is built to manage a 5 PSI max inlet pressure while providing a stable 7-11"wc outlet pressure. With a 1,250,000 BTU/hr max capacity, it is an ideal choice for high-demand equipment, ensuring consistent fuel delivery even during peak loads. This model incorporates Imblue Technology, a proprietary coating that enhances corrosion resistance in damp or outdoor environments. It meets rigorous ANSI Z21.80/CSA 6.22 standards for certified line pressure regulators, making it a reliable drop-in for technicians looking to maintain system integrity and precise gas pressure regulation in multi-appliance installations.

Key Benefits

• High Capacity Throughput: Rated for 1,250,000 BTU/hr, providing sufficient flow for heavy-duty commercial boilers and large furnaces.
• Imblue Technology: The specialized internal and external coating provides superior protection against harsh environmental conditions and corrosive gas constituents.
• Precision Pressure Control: The 7-11"wc outlet pressure range allows for fine-tuned calibration to meet specific manifold requirements.
• Integrated Safety: Features a factory-installed Overpressure Protection Device (OPD) to ensure downstream components remain protected from high-pressure surges.
• Versatile Mounting: Designed for multi-positional installation, simplifying field piping and HVAC maintenance in tight mechanical rooms.

Common Questions

Is a vent limiter required for this Maxitrol regulator?
When installed indoors, ANSI Z21.80 standards typically require a vent limiter or dedicated vent piping to the outdoors. The 325-7L series often utilizes a 12A39 vent limiter, but always verify local codes and the specific installation environment.

Can I use the 325-7ABL210D for propane (LP) applications?
Yes, this 1 1/4" NPT gas regulator is compatible with both natural gas and propane, provided the spring and orifice are correctly calibrated for the specific gravity of the gas being utilized.

What does the lever acting design offer compared to direct acting regulators?
The lever acting design provides higher sensitivity to pressure changes and improved lock-up characteristics, which is critical for preventing pilot outages and ensuring smooth burner ignition cycles.
