Maxitrol RV53-1 Regulator

The Maxitrol RV53-1 Regulator is a 1" NPT appliance gas regulator engineered for high-capacity industrial and commercial gas-fired equipment. This straight-thru-flow gas regulator utilizes a specialized conical valve design that allows gas to pass without directional changes, significantly reducing frictional resistance. This straight-thru flow design ensures precise regulation even at extremely low pressure differentials, making it an ideal choice for natural gas appliance pressure regulation and LP gas pressure control systems. With a 1/2 PSI max inlet pressure and a factory-set 3-6"wc outlet pressure range, this 1300000 BTU capacity regulator is suitable for furnaces, ovens, and large boilers where steady delivery is critical. The RV53-1 is fundamentally identical to the RV53-1-CSA model, maintaining ANSI Z21.18/CSA 6.3 compliance for main burner applications. Contractors should note this is a non-lockup type regulator and must only be used where downstream controls can handle line pressure.

• Straight-Thru-Flow Technology: Conical valve design provides the highest pressure drop capacity available for its size, handling up to 1,300,000 BTU/hr.
• High Precision: Delivers accurate, sensitive regulation through advanced internal dampening for improved stability and reduced "hunting."
• Multi-Positional Mounting: The RV53-1 supports flexible installation profiles, though vertical mounting is recommended when using vent limiters.
• Universal Compatibility: Fully approved for use with natural gas, manufactured gas, mixed gases, and liquefied petroleum (LP) gas-air mixtures.

Is the RV53-1 suitable for use as a line regulator?
No, this is an appliance gas regulator intended for main burner load only. It is a non-lockup type and should not be used as a line regulator ahead of low-pressure controls.

What is the difference between the RV53-1 and RV53-1-CSA?
The units are technically identical; both meet the same performance and safety standards for the North American market.

Does this regulator require a vent protector for outdoor use?
Yes, for outdoor installations, a vent protector such as the Maxitrol 13A15 should be used to prevent blockage from debris or weather.
