Maxitrol RV20VL-1/4-48 Regulator

When you're outfitting hearth products or high-end residential range tops, the Maxitrol RV20VL-1/4-48 Regulator is the industry standard for managing low-flow stability. This rubber seat poppet model is engineered specifically for main burner and pilot load applications where maintaining a precise flame at tiny flows is critical. Utilizing Maxitrol’s Straight-Thru-Flow (STF) design, this regulator reduces frictional resistance by allowing gas to pass through the conical valve without turbulence, ensuring peak capacity even at low inlet pressures.

The RV20VL-1/4-48 features a 1/4" NPT connection and handles a 1/2 PSI maximum inlet pressure with a high-performance 4-8" wc outlet pressure range. A standout feature for any technician is the integral vent limiting orifice, which simplifies the install by removing the need for a dedicated vent line to the outdoors. Housed in high-strength die-cast aluminum, this natural gas and LP compatible regulator supports multi-poise mounting, giving you the flexibility to install at any angle in tight appliance cabinets without sacrificing regulation accuracy.

• Precision Low-Flow Control: Specifically designed to handle the minimal flow requirements of pilots and small burners without cycling.
• Internal Vent Limiting: Features a 12A06 fixed orifice that limits gas escape in the event of diaphragm rupture, meeting safety codes for indoor installation without additional piping.
• Maximum Throughput: The Straight-Thru-Flow design maximizes flow capacity, supporting up to 65,000 BTU/hr depending on pressure drop.
• Installation Versatility: Certified for multi-positional mounting, allowing for vertical, horizontal, or angled orientation in restricted equipment spaces.
• Broad Compatibility: Constructed for use with Natural, Manufactured, Mixed, and LP gases, making it a versatile truck-stock item.

Does this regulator require an external vent line?
No. The "VL" designation indicates an integral vent limiter is factory-installed, which satisfies most code requirements for indoor venting without external piping.

Can I use this for a 2 PSI system?
Negative. This model is rated for an appliance-level 1/2 PSI max inlet. Using this on a 2 PSI line will damage the rubber seat and compromise the poppet assembly.

Is the outlet pressure adjustable?
Yes, the internal spring is rated for 4" to 8" water column. You can fine-tune the delivery pressure within this range to match the specific manifold requirements of the appliance.
