Maxitrol RV48CL-3/4 Regulator

The Maxitrol RV48CL-3/4 Regulator is a specialized rubber seat poppet model appliance gas regulator designed for high-performance gas flow control in main burner and pilot load applications. Built with a rugged aluminum housing and a 3/4" NPT connection, this unit is engineered to manage a 1/2 PSI maximum inlet pressure with a capacity up to 250,000 BTU/h. The field convertible design allows technicians to toggle between 5" w.c. natural gas and 10" w.c. LP gas outlet pressures, providing essential versatility for diverse job sites. This model features an integral vent limiting orifice, acting as a breather hole with a dust cap, which often eliminates the need for separate vent piping in indoor installations, provided it meets local codes. Its straight-thru flow design ensures minimal pressure drop and precise regulation even at low flow rates, making it a standard choice for residential and commercial cooking equipment, radiant heaters, and hearth products.

• Field Convertible Versatility: Easily switches between Natural Gas and Propane configurations to simplify truck stock.
• Enhanced Safety: Features an integral vent limiting orifice to minimize gas escapement in the event of a diaphragm rupture.
• High Precision: The rubber seat poppet ensures a positive seal and accurate regulation for pilot flow applications.
• Flexible Mounting: Suitable for multi-positional installation, though mounting in an upright position is recommended for maximum accuracy.

Can this regulator be used for outdoor applications?
While the unit is robust, the vent limiter is intended for indoor use. If installed outdoors, a 13A15 vent protector should be used to prevent blockage from the elements.

What is the maximum emergency exposure limits for this model?
The RV48 series is rated for emergency exposure up to 2.5 PSI; however, normal operating inlet pressure must not exceed 0.5 PSI (1/2 PSI).

Is an external vent line required?
Because this model includes a vent limiting device, it is typically exempt from requirements for a separate vent line to the outdoors, subject to local mechanical codes and appliance manufacturer specifications.
