Maxitrol 325-9L-1 1/2 Regulator

The Maxitrol 325-9L-1 1/2 is a professional-grade line pressure gas regulator engineered for high-demand residential, commercial, and industrial 2-psi piping systems. Featuring a robust 1 1/2" NPT connection, this lever-acting gas regulator supports a massive maximum capacity of 2,250,000 BTU/hr, making it a staple for multi-appliance configurations. It is specifically designed to provide positive dead-end lockup, ensuring precise downstream pressure control from full flow down to pilot light levels. This ANSI Z21.80/CSA 6.22 certified component is suitable for natural gas, LP, and mixed gas applications where maintaining a steady 7-11" w.c. outlet pressure is critical for equipment performance. Built with a high-leverage valve linkage, it handles a 2 PSI maximum inlet pressure with superior stability. For technicians working in varied environments, this model is compatible with vent limiting devices for indoor installs or vent protectors for outdoor protection against moisture and debris.

• High Capacity Performance: Manages up to 2,250,000 BTU/hr to service large boilers, furnaces, and commercial water heaters.
• Precision Lock-up Design: Lever-acting mechanism ensures safe positive dead-end lock-up for reliable pressure regulation.
• Multi-Position Mounting: Flexible installation options allow for efficient piping layouts in tight mechanical rooms.
• Broad Gas Compatibility: Field-proven for use with natural gas, propane (LP), and various gas-air mixtures.
• Durable Construction: High-quality aluminum housing provides long-term reliability in demanding HVACR environments.

Can this regulator be used for indoor installations?
Yes, when equipped with a factory-approved vent limiting device, it can be installed indoors without the need for dedicated vent piping to the atmosphere, provided it meets local mechanical codes.

Is an Overpressure Protection Device (OPD) required?
For systems exceeding 2 PSI nominal pressure, an OPD is typically required to comply with ANSI Z21.80 standards. Always verify specific system requirements based on your inlet pressure.

Does this model support pilot flow?
Absolutely. The Maxitrol 325-9L is designed to provide precise regulation even at extremely low flow rates, ensuring pilot lights remain stable during periods of no main burner demand.
