Maxitrol 325-9-2 Regulator

The Maxitrol 325-9-2 is a professional-grade 2 inch NPT gas regulator engineered for high-demand commercial gas line pressure regulation and industrial appliance service. This robust lever-acting design manages a significant 2,250,000 BTU/hr max capacity, ensuring precise control from full flow down to pilot flow applications. With a 10 PSI max inlet pressure rating and a versatile 4-12 inch WC outlet pressure range, it excels at maintaining stable downstream delivery in 2 PSI or 5 PSI piping systems. The positive dead-end lock-up feature is critical for preventing pressure creep during high-static, no-flow conditions, protecting sensitive downstream components. Built with high-leverage valve linkage and a durable aluminum housing, this regulator provides the precise pressure control required for large-scale boilers, water heaters, and industrial furnaces. When utilized as a line pressure regulator indoors, ensure the installation includes a certified vent limiting device like the 12A49 to meet local code requirements without the need for external vent piping.

• High Capacity Performance: Supports massive loads up to 2.25 million BTU/hr, making it the standard for large industrial gas regulators.
• Dead-End Lock-Up: The lever-acting design provides a tight seal to prevent downstream pressure spikes when appliances are cycled off.
• Multi-Poise Installation: Suitable for various mounting orientations, though an upright horizontal position is required if a vent limiter is installed.
• Extreme Durability: Capable of withstanding emergency exposure limits up to 65 PSI on the inlet side without internal damage.
• Broad Application Range: Compatible with natural, manufactured, mixed, and liquefied petroleum gases.

• What is the purpose of the 12A49 vent limiter? It is used for indoor installations to restrict gas escapement in the event of a diaphragm failure, removing the requirement to run a vent line to the atmosphere.
• Can this handle high-pressure surges? Yes, the Maxitrol 325-9-2 is rated for an operating inlet pressure of up to 10 PSI and high emergency exposure, though it does not provide downstream over-pressure protection.
• Is this regulator suitable for LP gas? Absolutely. It is certified for use with LP gas-air mixtures and liquefied petroleum gases in both appliance and line regulation roles.
