Maxitrol RV52-3/4 Regulator

The Maxitrol RV52-3/4 Regulator is a job-ready 3/4" NPT gas regulator engineered for high-capacity performance in low-pressure gas systems. Built with the veteran contractor in mind, this straight-thru-flow appliance regulator utilizes a conical valve design that minimizes frictional resistance, allowing for a significantly higher flow rate compared to standard poppet-style regulators. This RV52-3/4 gas pressure regulator and its direct cross-reference counterparts, the RV52-3/4-CSA and RV52-66, are rated for a maximum inlet pressure of 1/2 PSI (14" w.c.) and are shipped with a 3-6" w.c. adjustable outlet spring, factory-set to a standard 3.5" w.c. nominal output.

This HVAC gas regulator is suitable for multi-positional mounting, though installing with a vent limiting device may require an upright orientation to meet local codes. As an ANSI Z21.18/CSA 6.3 certified component, it is compatible with natural gas, manufactured, mixed, and liquefied petroleum (LP) gas-air mixtures. The rugged aluminum housing ensures thermal stability across an operating range of -40°F to 205°F, making it a reliable choice for commercial and industrial gas burner systems where sensitive regulation at low pressure differentials is critical for efficient combustion.

• Straight-Thru-Flow Design: Maximizes flow capacity and reduces pressure drop across the 3/4 inch NPT regulator.
• Broad Fuel Compatibility: Fully rated for Natural Gas, LP, and mixed gas applications.
• Precise Pressure Response: High-sensitivity poppet provides accurate regulation even at extremely low pressure differentials.
• Durable Aluminum Construction: Lightweight yet robust housing handles demanding boiler and furnace room environments.
• Universal Replacement: Directly replaces RV52-3/4-CSA and RV52-66 models without piping modifications.

What is the maximum BTU capacity for the RV52-3/4?
When utilized in standard configurations, this high capacity gas regulator can handle up to approximately 900,000 BTU/hr depending on specific gravity and pressure drop requirements.

Can I use this regulator for a lock-up application?
No, the Maxitrol RV52 series is a non-lockup type regulator. It should only be installed where downstream controls can handle line pressure or in main burner applications according to gas regulator installation standards.

Is a vent limiter required for this model?
While the RV52 is multi-positional, always check local jurisdictional requirements. If a 12A06 ball-check vent limiter is installed for indoor gas appliance regulation, the unit must be mounted in the upright horizontal position.
