Maxitrol RV48-1/2-12A04 Regulator

The Maxitrol RV48-1/2-12A04 is a professional-grade rubber seat poppet gas regulator engineered for precision control in residential and commercial appliance manifolds. Featuring a 1/2" NPT connection and a durable aluminum housing, this regulator is designed for main burner and pilot load applications where maintaining a stable 3-6" w.c. outlet pressure is critical. It handles a 1/2 PSI maximum inlet pressure and is compatible with natural gas, LP gas, and air mixtures, making it a versatile component for water heaters, commercial ranges, and boilers. This specific model comes equipped with a 12A04 vent limiter, an automatic ball-check device that eliminates the need for external vent piping by limiting gas leakage in the event of a diaphragm rupture. For installers, the poppet-style design ensures high sensitivity and accurate regulation even at low-pressure differentials, while the vibration-resistant adjusting screw maintains setpoints in demanding environments.

Key Benefits:

• Integrated Venting: Includes a Maxitrol 12A04 vent limiter for indoor installations, permitting fast diaphragm response while meeting ANSI Z21.18 standards.
• High Flow Capacity: Supports up to 230,000 BTU/hr (Natural Gas), providing reliable delivery for high-demand appliances.
• Multi-Fuel Compatibility: Certified for use with natural, manufactured, mixed, and liquefied petroleum gases.
• Compact Poppet Design: Ideal for tight equipment manifolds, offering the ultimate in low-flow stability and lockup performance.

Common Questions:

Can the RV48-1/2-12A04 be mounted in any orientation?
When equipped with the 12A04 vent limiter, the regulator must be mounted in an upright horizontal position. Any other orientation can interfere with the ball-check mechanism and lead to improper regulation or pilot outages.

What is the difference between this and the "L" version?
The standard RV48 features a higher regulation capacity compared to the "L" (limited) models, which are often used for fixed orifice applications. Always check the required MBTU/h for your specific burner to ensure proper sizing.

Is an external vent line required for this regulator?
No, the 12A04 ball check device serves as a certified vent limiter for indoor use, provided it is installed directly into the 1/8" NPT vent boss as intended by the manufacturer.
