Maxitrol 325-3L48-1/2-LIM Regulator

The Maxitrol 325-3L48-1/2-LIM is a high-performance line pressure regulator engineered specifically for 2-PSI piping systems and natural gas applications. This lever-acting regulator manages a maximum inlet pressure of 5 PSI for natural gas and 2 PSI for LP gas, delivering a consistent 7-11" w.c. outlet pressure. Designed for high-demand loads, it supports a maximum individual load capacity of 200,000 BTU/hr. The integration of vent limiters eliminates the need for vent piping to the outdoors, provided the unit is installed in a well-ventilated area according to local codes. This 1/2" NPT gas regulator features an Overpressure Protection Device (OPD), ensuring downstream components are protected during high-pressure scenarios. Built for durability and precision, the 325-3L48-1/2-LIM is a staple for contractors installing CSST piping systems or high-efficiency furnaces and boilers requiring stable manifold pressure.

• Internal Vent Limiter: Simplifies installation by removing the requirement for dedicated vent lines to the atmosphere.
• Overpressure Protection: Integrated OPD design ensures safety for downstream appliances in 2-PSI piping systems.
• Lever-Acting Design: Provides superior regulation and rapid response to load changes for high-capacity gas equipment.
• Certified Performance: Meets rigorous standards for line pressure regulation in residential and commercial settings.
• Installation Flexibility: Optimized for use with both natural gas and liquid propane systems with appropriate inlet adjustments.

Common Questions

Can the Maxitrol 325-3L48 be installed outdoors?
Standard 325 series regulators are designed for indoor use. If used outdoors, a vent protector must be installed to prevent moisture and debris from entering the vent hole, and the unit must be protected from direct weather exposure.

Does this regulator require a separate vent line?
When equipped with the factory-installed 13A15 vent limiter, this regulator does not require a vent line to the outdoors, effectively reducing labor and material costs during installation.

How do I confirm if the 200,000 BTU capacity meets my requirements?
Calculate the total connected load of the appliance. The 325-3L-48 is rated for a maximum individual load of 200,000 BTUs; if the appliance exceeds this, a larger 325-5 or 325-7 series may be required.
