Maxitrol 325-7A-1 1/4 Regulator

The Maxitrol 325-7A-1 1/4 is a professional-grade gas pressure regulator designed for high-capacity applications in residential, commercial, and industrial settings. Utilizing a specialized lever-acting design, this unit facilitates precise pounds-to-inches pressure reduction for a variety of fuel gases, including natural, manufactured, mixed, and liquefied petroleum gases. With a rugged aluminum housing, it supports multi-positional mounting and is capable of maintaining accurate control from full load down to pilot flow, making it a reliable line pressure regulator for main burner or pilot applications.

This 1-1/4" NPT regulator is engineered to handle a maximum inlet pressure of 10 PSI and is factory-supplemented with a positive dead-end lock-up feature, ensuring safety and performance by stopping gas flow completely when the downstream valve is closed. The 1,250,000 BTU/hr capacity makes the 325-7A an essential component for high-demand equipment. For indoor installations, the unit's 1/2" NPT vent connection is compatible with Maxitrol vent limiters, like the 12A49, to meet safety codes without the need for external vent lines.

Key Benefits:

• High Capacity Performance: Supports a 1,250,000 BTU maximum capacity, ideal for large boilers and industrial furnaces.
• Precise Pressure Regulation: Features a wide 4-12" w.c. outlet pressure range for fine-tuning downstream gas delivery.
• Positive Dead-End Lock-Up: Provides a tight seal at zero flow conditions, preventing downstream pressure creep.
• Durable Construction: Built with a high-strength aluminum body suitable for temperatures ranging from -40°F to 205°F.
• Versatile Application: Certified for multiple gas types and usable as a single-stage regulator or line regulator.

Common Questions:

Can the Maxitrol 325-7A be used for 2 PSI piping systems?
Yes, it is regularly utilized in 2 PSI to 5 PSI systems to reduce pressure to appliance-level inches of water column. Ensure your specific configuration matches the spring range and inlet limitations.

Is a vent limiter required for this regulator?
If the Maxitrol 325-7A-1 1/4 is installed indoors and you do not wish to run a dedicated vent line to the atmosphere, a compatible vent limiting device must be used to comply with local mechanical codes.

What is the difference between the 325-7A and the 325-7AL?
The "A" designation typically refers to the regulator's specific high-leverage linkage for appliance applications, while the "L" denotes a line pressure regulator specifically certified under ANSI Z21.80 for high-pressure distribution systems.
