Maxitrol RV47L-1/2 Regulator

The Maxitrol RV47L-1/2 Regulator is a straight-thru design appliance gas regulator engineered for high-capacity applications where precise pressure control is non-negotiable. This 1/2" NPT housing features a rubber seat poppet for superior lock-up and consistent regulation across a wide range of flow rates. With a 1/2 PSI max inlet pressure and an adjustable 2.8-5.2" wc outlet pressure range, this unit is built for technical reliability in residential and light commercial gas appliance installation. The integral vent limiting orifice eliminates the need for vent piping to the outdoors, provided local codes are met, simplifying gas pressure regulator mounting in tight mechanical spaces. It is specifically calibrated for use with natural, manufactured, mixed, liquefied petroleum gases, and LP gas-air mixtures, making it a versatile HVAC replacement part for high-demand equipment like boilers, water heaters, and commercial cooking lines.

Key Benefits for Technicians:

• Multi-Positional Mounting: Designed for installation in upright, horizontal, or inverted positions to accommodate complex piping layouts.
• Vent Limiting Technology: The factory-installed integral vent limiter ensures safe operation by restricting gas escapement in the event of diaphragm rupture.
• High Sensitivity: The rubber seat poppet ensures positive shut-off and maintains stable delivery pressures despite fluctuations in supply.
• Durable Construction: Heavy-duty aluminum casting stands up to the rigors of mechanical room environments.
• Precise Calibration: Optimized for an outlet pressure range of 2.8 to 5.2 inches water column, ideal for high-efficiency burners.

Common Questions:

Does the RV47L-1/2 require a separate vent line?
No, this model includes an integral vent limiting orifice, which typically satisfies code requirements for indoor installation without external venting, though you should always verify with local AHJ regulations.

Can I use this regulator for propane (LP) applications?
Yes, the Maxitrol RV47L-1/2 is rated for LP gas. However, ensure the spring is correctly calibrated for the higher pressure requirements typically associated with liquid petroleum systems.

What is the maximum flow capacity for this unit?
The RV47 series is designed for high flow gas regulation. Specific BTU capacity depends on the pressure drop across the regulator; refer to the Maxitrol flow charts for exact sizing relative to your appliance load.
