Maxitrol 325-3L-3/8 Regulator

The Maxitrol 325-3L-3/8 is a professional-grade line pressure regulator designed specifically for high-performance piping systems. This lever acting design gas regulator handles a 2 PSI max inlet pressure, making it a critical component for transitioning from high-pressure piping to lower-pressure appliance manifolds. Featuring 3/8" NPT connections, it supports a 140,000 BTU/hr max individual load and up to 250,000 BTU/hr max multiple load capacity. Engineered for precision, the unit provides a local 7-11" w.c. outlet pressure range, ensuring consistent delivery for sensitive gas valves. The positive dead-end lock-up capability is essential for safety, preventing downstream pressure creep when the appliance is inactive. Technicians utilize this certified gas regulator for CSST piping and copper tubing systems where reliable gas pressure regulation is required to maintain equipment efficiency and prevent over-pressure faults in residential or light commercial footprints.

• Positive Dead-End Lock-Up: Ensures 0% leakage during gas-off cycles, protecting downstream components from high-pressure exposure.
• Lever Acting Design: Provides superior stable pressure control and quick response to changes in gas flow demand.
• Multi-Poise Installation: Can be mounted in various orientations, though upright is preferred for the most accurate gas pressure drop management.
• High BTU Capacity: Manages up to 250,000 BTU/hr for multiple appliance headers, reducing the footprint of the gas train.
• Precision Spring Loading: Pre-set for 7-11" w.c., allowing for fine-tuned calibration to meet specific appliance manifold requirements.

Can the Maxitrol 325-3L be installed outdoors?
Yes, provided it is equipped with a certified vent protector and installed in compliance with local codes to prevent water or debris from entering the vent bridge.

What is the purpose of the 325-3L over standard 325 series units?
The "L" designation indicates a limited relief device, allowing for specific indoor installation protocols without the traditional need for plumbing a vent line to the outdoors in certain jurisdictions.

Is this regulator compatible with Propane (LP) or Natural Gas?
The Maxitrol 325-3L-3/8 is primarily designed for Natural Gas applications, but it can be used in LP gas systems when properly sized and specified for the higher specific gravity of propane.
