Maxitrol 325-5BL48-3/4 Regulator

The Maxitrol 325-5BL48-3/4 is a specialized certified line pressure gas regulator engineered for high-performance 2-psi piping systems. Featuring a 3/4" NPT connection, this lever-acting design manages a 5 PSI max inlet pressure while maintaining a stable 7-11" w.c. outlet pressure. Designed with Imblue Technology, this unit provides superior corrosion resistance, making it suitable for both indoor and outdoor service in residential, commercial, and industrial gas applications. With a 320,000 BTU/hr capacity, it effectively handles high-demand loads for furnaces, boilers, and water heaters. The integrated over-pressure protection device (OPD) and positive dead-end lockup ensure system integrity during downstream shutdowns. This regulator is rated for a wide range of media including natural gas, LP, and mixed gases, operating reliably within an ambient temperature range of -40°F to 205°F.

Key Benefits for Contractors

• Corrosion Resistance: Imblue Technology coating ensures durability in harsh environments and coastal installations.
• Precise Pressure Control: High-sensitivity lever-acting design provides accurate gas pressure regulation for sensitive electronic ignition appliances.
• Enhanced Safety: Built-in OPD (Over Pressure Device) complies with ANSI Z21.18/CSA 6.3 standards for line pressure regulators.
• System Versatility: Capable of managing multi-appliance loads with a total capacity of 320,000 BTU/hr.
• Dead-End Lockup: Features a positive dead-end lockup mechanism to prevent pressure creep during periods of no flow.

Technical Questions & Answers

Can the Maxitrol 325-5BL48 be used for outdoor installations?
Yes, this model features Imblue Technology, a specialized coating that protects the aluminum housing from atmospheric corrosion, making it suitable for outdoor exposed piping.

What is the maximum inlet pressure rating?
The Maxitrol 325-5BL48-3/4 is certified for a 5 PSI maximum inlet pressure, though it is tested to withstand emergency exposure up to 65 PSI without failure.

Is an external vent limiter required?
This regulator is a certified line pressure regulator. Depending on local mechanical codes and installation orientation, a vent limiting device may be utilized to eliminate the need for piping a vent line to the outdoors.
