Maxitrol RV20VL-1/4-812 Regulator

The Maxitrol RV20VL-1/4-812 is a precision-engineered appliance gas regulator specifically designed for main burner and pilot load applications where accurate control of low flow rates is required. This rubber seat poppet model features 1/4" NPT ports and is constructed with a high-strength aluminum die-cast housing for long-term field reliability. It is built to handle a maximum inlet pressure of 1/2 PSI and is factory-calibrated for an 8-12" w.c. outlet pressure range, making it a critical component for gas pressure regulation in residential and commercial cooking equipment, hearth products, and pilot lines. The integral vent limiting orifice acts as a breather hole, eliminating the need for a separate vent line to the outdoors in most jurisdictions, while the 5/16-24 threaded vent connector allows for 1/8” tubing if necessary. This Maxitrol regulator utilizes a straight-thru-flow design to maintain high capacities at low pressure differentials, ensuring stable performance across natural gas and LP gas applications.

Key Benefits

• Precise Low-Flow Control: The rubber seat poppet design ensures sensitive and accurate regulation for pilot load applications and small burner cycles.
• Vent Limiting Technology: Features an integral vent limiting orifice that simplifies installation by reducing the need for external vent piping.
• Multi-Position Mounting: Qualified for installation at any angle or plane, providing maximum flexibility in tight appliance cabinets (excluding 'D' suffix models).
• Versatile Fuel Compatibility: Fully suitable for use with natural, manufactured, mixed, liquefied petroleum gases, and LP gas-air mixtures.
• Rugged Construction: The aluminum die-cast housing provides superior durability in high-ambient temperature environments up to 225°F.

Common Questions

Can this regulator be used for high-pressure industrial lines?
No, this model is rated for a maximum inlet pressure of 1/2 PSI. It is specifically intended for low-pressure gas appliance regulation and is not suitable for high-pressure distribution lines.

Does the RV20VL-1/4-812 require a vent line to the outdoors?
Because it includes an integral vent limiting orifice, it typically does not require a vent line. However, always verify local mechanical codes and specific appliance requirements during installation.

Is this regulator compatible with both Natural Gas and Propane?
Yes, the Maxitrol RV20VL series is compatible with NG and LP gas, provided the outlet pressure spring range (8-12" w.c.) matches your appliance's manifold requirements.
