Maxitrol RV47LF-4L6-0008 Regulator

The Maxitrol RV47LF-4L6-0008 is a professional-grade appliance gas regulator specifically engineered for high-precision control in low-flow burner and pilot applications. As a veteran technician knows, the rubber seat poppet design is essential for maintaining a steady 8.0" W.C. outlet pressure, particularly in modern high-efficiency residential and light commercial equipment. This non-adjustable gas regulator comes factory-set to eliminate field calibration errors, ensuring consistent manifold pressure for propane (LP), natural, or mixed gas systems.

Constructed with a heavy-duty die-cast aluminum housing, the RV47LF-4L6-0008 features a 1/2" NPT inlet and a 3/8" Loxit outlet, rated for a 1/2 PSI maximum inlet pressure. A critical integration is the integral vent limiting orifice, which satisfies code requirements for many indoor installations by removing the need for external vent piping. With a maximum capacity of 125,000 BTU/hr for burner-only applications, this multi-poise unit allows for flexible mounting orientations in tight furnace cabinets or commercial cooking banks.

• Precise Gas Regulation: Optimized for low gas volumes to prevent pilot outage and flickering.
• Internal Vent Limiter: Simplifies installation by eliminating dedicated vent lines to the outdoors.
• Multi-Position Mounting: High-strength construction supports orientation in any plane.
• Tamper-Proof Design: Factory-set 8" W.C. prevents unauthorized or incorrect field adjustments.
• Broad Compatibility: Suitable for LP gas, manufactured gas, and mixed gas-air systems.

Can I adjust the outlet pressure on this model?
No, this is a non-adjustable model factory-set to 8.0" W.C. to ensure specific HVAC appliance safety standards are met without the risk of over-firing.

Does this regulator require an external vent line?
This unit includes a built-in vent limiting orifice. While it typically eliminates the need for a vent line, always verify local mechanical codes regarding indoor discharge.

What is the maximum BTU capacity?
The capacity varies by application: 40,000 BTU/hr for fixed orifices, 90,000 BTU/hr for burner and pilot setups, and up to 125,000 BTU/hr for burner-only service.
