Maxitrol RV47D-3/8 Regulator

The Maxitrol RV47D-3/8 is a high-performance appliance gas regulator engineered for precision in residential and commercial cooking equipment. Featuring a rubber seat poppet design, this unit ensures reliable gas flow control for both main burner and pilot load applications. It is rated for 3/8" NPT pipe sizes and handles a 1/2 PSI maximum inlet pressure with an outlet pressure range of 2.8 to 5.2" w.c., making it compatible with natural gas, LP, and mixed gas systems. A defining technical feature is the integral ball check limiting device, which allows for normal opening while restricting the closing cycle to prevent system surges. The D-suffix model is specifically designed for horizontal mounting to maintain accuracy within its 125,000 BTU/h capacity envelope. Built with a high-strength aluminum die-cast housing, this regulator is the industry standard for hearth products and pilot line precision.

• Precise Low-Flow Control: Specifically designed to manage tiny flows in pilot lines and main burners without sacrificing accuracy.
• Enhanced Safety: The integral ball check acts as a vent limiting device, reducing the risk of unsafe gas release during operation.
• Rugged Construction: Aluminum die-casting and a rubber poppet seat ensure longevity in high-ambient temperature environments up to 225°F.
• Multi-Fuel Versatility: Certified for use with liquefied petroleum gases and natural gas, simplifying truck stock requirements.

• Can this regulator be mounted in any orientation? No, the "D" suffix indicates that this specific model must be mounted horizontally for the poppet to function within specified pressure tolerances.
• Is a separate vent limiter required? This model includes an integral ball check limiting device, which typically meets code requirements for vent limiting without additional external piping.
• What gases is the RV47D compatible with? It is suitable for natural, manufactured, mixed, and LP gas-air mixtures.
