Maxitrol RV47D-1/2 Regulator

The Maxitrol RV47D-1/2 is a professional-grade straight-thru flow appliance regulator designed for high-performance gas pressure regulation in residential and light commercial applications. Featuring a 1/2" NPT pipe size and a rubber seat poppet configuration, this unit ensures precise control of natural gas or liquid petroleum. The integrated ball check limiting device is a critical safety feature, permitting a normal opening cycle while effectively restricting the closing cycle to prevent sudden pressure spikes. With a maximum inlet pressure of 1/2 PSI and a factory-calibrated outlet pressure range of 2.8" to 5.2" w.c., it provides the stable manifold pressure necessary for modern high-efficiency heating equipment. Built with a rugged die-cast aluminum body, the RV47D-1/2 gas regulator is the industry standard for maintaining consistent BTU output under fluctuating line pressures. It is an essential component for any technician performing targeted gas pressure troubleshooting or equipment retrofits requiring reliable Maxitrol RV47D-1/2 specifications for appliance safety.

• Integral Limiting Device: Features a factory-installed ball check that manages the closing cycle speed, eliminating the need for external vent piping in most jurisdictions.
• Precise Pressure Regulation: Optimized for sensitive electronic ignition systems, maintaining a tight 2.8-5.2" w.c. window for burner efficiency.
• Durable Poppet Design: The rubber seat poppet ensures a positive shut-off and long-term durability in environments with high cycling demands.
• Universal Compatibility: Standard 1/2 inch gas regulator threading allows for seamless integration into existing furnace, water heater, or boiler gas trains.

Common Questions

Can the Maxitrol RV47D-1/2 be mounted in any orientation?
For optimal performance and to satisfy local mechanical codes, the RV47D-1/2 should be mounted upright in a horizontal pipe run. Mounting it vertically or upside down can affect the calibration of the internal spring and poppet assembly.

How do I adjust the outlet pressure on this regulator?
After verifying the inlet pressure does not exceed 0.5 PSI, remove the top cap and use the adjustment screw. Turning clockwise increases the manifold pressure, while counter-clockwise decreases it within the 2.8" to 5.2" w.c. range.

Is a vent protector required for this model?
Because this model includes an integral ball check limiting device, it is often classified as a vent-limited regulator. However, always verify with local AHJ codes regarding the specific installation environment.
