Maxitrol RV20VL-3/8-48 Regulator

The Maxitrol RV20VL-3/8-48 is a professional-grade appliance gas regulator engineered for precision in residential and light commercial systems. Featuring a 3/8" NPT connection and a durable rubber seat poppet, this regulator is purpose-built for main burner and pilot applications where maintaining stable, low-flow control is critical. With a maximum inlet pressure of 1/2 PSI and a factory-set outlet range of 4-8" w.c., it ensures equipment operates at peak efficiency. The integrated vent limiting orifice acts as a physical breather hole, eliminating the need for external vent lines in most indoor installations, provided it meets local codes. Constructed from high-strength aluminum die castings, the RV20VL supports multi-position mounting for flexible installation in tight mechanical spaces. This unit is compatible with natural gas, LP, and mixed gas systems, delivering the consistent drift-free performance service technicians require for modern hearth products and cooking appliances.

Key Benefits

• Integrated Vent Limiting: Features a 12A04 vent limiter that functions as a breather hole, simplifying installation by reducing the need for additional piping.
• Precision Flow Control: The rubber seat poppet design is optimized for tiny flows, making it an ideal pilot gas regulator for sensitive equipment.
• Versatile Mounting: Certified for multi-position installation, allowing for vertical, horizontal, or angled placement without compromising pressure stability.
• Heavy-Duty Construction: Built with a rugged aluminum housing to withstand the high-demand environments of commercial kitchens and HVAC systems.
• Universal Gas Compatibility: Engineered to handle natural gas, manufactured, mixed, and LP gas-air mixtures with high reliability.

Common Questions

What is the maximum capacity of the RV20VL-3/8-48?
This 3/8" model typically handles up to 65,000 BTU/hr for main burner loads or 50,000 BTU/hr when managing both burner and pilot loads simultaneously.

Does this regulator require an external vent line?
No, the vent limiting orifice is designed to limit the escape of gas to within ANSI standards in the event of a diaphragm rupture, usually removing the requirement for downstream venting.

Can I use this for propane applications?
Yes, the RV20VL is rated for use with LP gas. Ensure the 4-8" w.c. outlet pressure range matches your appliance requirements before installation.
