Maxitrol RV48L-3/4 Regulator

The Maxitrol RV48L-3/4 Regulator is a technical-grade appliance gas pressure regulator engineered for precision fuel management in high-demand residential and commercial systems. This 3/4" NPT gas regulator features a rubber seat poppet design, optimized for maintaining stable outlet pressures between 3-6" w.c. even during fluctuating demand. With a maximum inlet pressure of 1/2 PSI, it is the industry standard for natural gas appliances, including commercial ranges, boilers, and high-capacity water heaters. The straight-thru flow design maximizes BTU capacity—rated up to 250,000 BTU/hr—while minimizing pressure drop across the valve body. For enhanced safety and streamlined installation, this model includes an integral vent limiting orifice, eliminating the need for external vent piping in most compliant indoor applications. Constructed with a high-strength aluminum housing, the Maxitrol RV48L is rated for ambient temperatures up to 225°F, ensuring reliable performance in hot mechanical rooms and commercial kitchens. Whether you are performing a gas regulator replacement or a new system HVAC installation, this Maxitrol RV series component provides the mechanical consistency required for appliance gas systems.

• Advanced Flow Geometry: The straight-thru flow design ensures maximum BTU capacity for high-output appliances without compromising pressure stability.
• Integrated Safety: Features an integral vent limiting orifice (12A06) that reduces installation complexity by meeting safety codes for indoor venting.
• Precision Control: The rubber seat poppet provides superior shut-off characteristics and handles "tiny flows" for pilot light stability.
• Versatile Mounting: Designed for multi-positional mounting, allowing for flexible pipe routing in tight mechanical footprints.
• Wide Compatibility: Suitable for natural gas, manufactured, mixed, and LP gas-air mixtures.

• What is the maximum BTU rating for the Maxitrol RV48L-3/4? This 3/4" NPT model supports a main burner range of regulation up to 250,000 BTU/hr, making it suitable for larger commercial cooking equipment and furnaces.
• Does this regulator require an external vent line? No, the integral vent limiting orifice acts as a breather hole that limits gas escape in the event of a diaphragm rupture, typically satisfying code requirements for ventless indoor installation.
• Can I use this for Propane (LP) applications? Yes, the Maxitrol RV series is rated for LP and LP gas-air mixtures, though you must ensure the 3-6" w.c. outlet pressure matches your appliance's manifold requirements.
