Maxitrol RV91-2 Regulator

The Maxitrol RV91-2 is a high-capacity straight-thru-flow (STF) gas pressure regulator designed for superior performance in large-scale residential, commercial, and industrial gas applications. Featuring a 2" NPT connection, this regulator utilizes a unique conical valve design that allows gas to flow directly through the body without directional changes, significantly reducing turbulence and increasing 3275 CFH flow capacity. It is engineered to provide precise, sensitive regulation even at low pressure differentials, making it an essential component for maintaining stable outlet pressure between 3" and 6" WC. The RV91-2 is multi-poise, though upright mounting is recommended for maximum efficiency. It is compatible with Natural, Liquefied Petroleum (LP), and Mixed Gases. Built with a durable aluminum housing, it withstands ambient temperatures from -40°F to 205°F. This gas appliance regulator is CSA certified for 1/2 PSI max inlet pressure and has been Maxitrol tested to handle up to 1 PSI, ensuring steady delivery to high-demand burners and boilers.

Key Benefits for the Contractor

• Straight-Thru-Flow Design: Minimizes pressure drop and internal friction, allowing for smaller pipe sizes in high-volume applications than standard offset regulators.
• High-Volume Capacity: Rated for up to 3275 CFH, delivering consistent gas volume to large manifolds and heavy-duty industrial appliances.
• Precision Pressure Control: Maintains tight outlet pressure tolerances (3-6" WC range) to prevent pilot outages and ensure clean combustion.
• Industrial Build Quality: Rugged aluminum construction provides reliable service in demanding mechanical rooms and outdoor enclosures.
• Universal Gas Compatibility: Approved for use with Natural Gas, LP, and air-gas mixtures, simplifying inventory for mixed-fuel job sites.

Common Questions

What is the maximum inlet pressure for the Maxitrol RV91-2?
The unit is CSA certified for 1/2 PSI (14" WC) maximum inlet pressure. However, it is Maxitrol tested for higher performance up to 1 PSI, though local codes usually dictate adherence to the CSA rating for appliance regulators.

Can the RV91-2 be used for LP gas?
Yes, this regulator is fully compatible with LP gas, as well as natural gas, manufactured gas, and LP gas-air mixtures.

Does this regulator require a specific mounting orientation?
While the STF design allows for flexibility, it is professionally recommended to mount the regulator in an upright position. If mounted in any other position, the outlet pressure may deviate from the factory spring setting and require field adjustment.
