Maxitrol RV47AL-1/2 Regulator
The Maxitrol RV47AL-1/2 is a professional-grade appliance gas regulator engineered for precise low-flow control in residential and commercial gas-fired equipment. This 1/2" NPT gas regulator is a direct replacement for the legacy RV47L-1/2 model, featuring a durable rubber seat poppet design that ensures a positive seal and consistent performance across various gas media, including natural, manufactured, mixed, and LP gases. Designed to handle a maximum inlet pressure of 1/2 PSI, it effectively manages outlet pressure ranges of 3.8" to 4.3" w.c., making it critical for maintaining stable manifold pressure in furnaces, boilers, and water heaters.
For field technicians, the RV47AL-1/2 offers logistical flexibility with its multi-position mounting capability and high-strength aluminum die-cast housing. The inclusion of an integral vent limiting orifice simplifies installation by meeting code requirements without the need for additional vent piping in most standard applications. Rated for a flow capacity of .15 CFH and CSA certified, this regulator is the standard for pilot load and main burner regulation where accuracy and long-term reliability are non-negotiable for system safety and efficiency.
Key Benefits for Contractors
- Precision Regulation: Engineered specifically for low-flow sensitivities in main burner and pilot applications.
- Vent Limiting Orifice: Integrated safety feature reduces installation time and material costs.
- Rugged Construction: Die-cast aluminum body provides high torque resistance and thermal stability.
- Droop Compensation: Maintains tight control over outlet pressure even during fluctuating inlet conditions.
- Field Versatility: Suitable for a wide array of gas mixtures with a 2.5 PSI emergency exposure limit.
Common Questions
Can I use the RV47AL-1/2 for liquid LP applications?
No, this is a vapor-stage regulator. It is designed for use with LP gas-air mixtures and vaporized propane but should not be used in direct liquid service.
Is an external vent line required for this regulator?
The RV47AL-1/2 features an integral vent limiter. In most jurisdictions, this satisfies the requirement to prevent dangerous gas discharge in the event of a diaphragm failure, but always verify local mechanical codes.
Can I adjust the outlet pressure beyond the 3.8"-4.3" w.c. range?
This model features limited spring adjustment. It is factory-set to maintain the 3.8" to 4.3" w.c. range to ensure appliance compatibility and safety; it should not be forced beyond these calibrated limits.
