Maxitrol RV48L-1/2-512 Regulator

The Maxitrol RV48L-1/2-512 is a high-performance rubber seat poppet type regulator designed for precise pressure control in main burner and pilot load applications. Featuring a 1/2" NPT connection and a robust aluminum die-cast housing, this unit handles a 1/2 PSI maximum inlet pressure while maintaining a stable 5-12" WC outlet pressure. Engineered specifically for appliances requiring accurate flow regulation, the RV48L model includes an integral vent limiting orifice, eliminating the need for external vent piping in indoor installations where gas escapement must be restricted. This multi-poise mounting regulator is suitable for natural gas, manufactured, mixed, and LP gas-air mixtures. Whether you are servicing commercial cooking equipment or high-end residential hearth products, this appliance gas regulator ensures consistent manifold pressure and optimal combustion efficiency. The poppet design is particularly effective for managing tiny flows, making it a critical component for modern HVACR and boiler systems.

Key Benefits

• Integrated Vent Limiter: Features a factory-installed 12A06 fixed orifice vent limiter for safe indoor operation without additional piping.
• Multi-Poise Installation: Designed for versatile mounting in any plane or angle, though horizontal mounting is recommended for maximum precision.
• Broad Fuel Compatibility: Fully rated for use with natural, mixed, and LP gases, offering flexibility for various field applications.
• Precision Low-Flow Control: The rubber seat poppet design provides superior shut-off and regulation for small pilot flows and main burner loads.
• Durable Construction: High-strength aluminum die-cast body ensures long-term reliability in demanding mechanical room environments.

Common Questions

Does this regulator require an external vent line?
No. The "L" suffix in RV48L-1/2-512 signifies an integral vent limiting orifice. It is designed to limit gas escapement to safe levels in the event of diaphragm failure, making it suitable for indoor use without a dedicated vent line to the atmosphere.

Can I use this for outdoor propane applications?
While compatible with LP gas, vent limiters are not intended for outdoor use where they are exposed to the elements. For outdoor installations, a standard vent protector or specific outdoor-rated housing should be utilized.

What is the maximum BTU capacity for this model?
The Maxitrol RV48L-1/2 is typically rated for approximately 230,000 BTU/hr, though actual capacity depends on the specific pressure drop and gravity of the gas being used.
