Maxitrol RV48L-3/4-48 Regulator

The Maxitrol RV48L-3/4-48 Regulator is a specialized rubber seat poppet model engineered for high-precision pressure management in main burner and pilot load applications. Featuring a 3/4" NPT connection, this appliance gas regulator is built with a high-strength aluminum die-cast housing, ensuring reliable gas pressure control for commercial cooking equipment, boilers, and hearth products. The integral vent limiting orifice acts as a dedicated breather hole, eliminating the need for external vent piping in indoor installations by safely restricting gas escapement in the event of diaphragm rupture. Optimized for low-flow sensitivity, this unit manages a 1/2 PSI max inlet pressure while maintaining a stable 4-8"wc outlet pressure. Field-tested for multi-poise mounting, the RV48L-3/4-48 supports versatile installation angles, making it a critical HVAC replacement part for technicians requiring ANSI Z21.18 compliant components that handle natural, manufactured, mixed, and LP gases efficiently.

• Precise Low-Flow Control: The rubber seat poppet design is specifically optimized for maintaining accuracy during tiny flows, ideal for pilot circuits.
• Self-Limiting Safety: Includes an internal vent limiter, which removes the requirement for a separate vent line to the outdoors in most indoor applications.
• Durable Construction: Built with a rugged aluminum body and stainless steel internals to withstand demanding mechanical room environments.
• Multi-Poise Mounting: Capable of being installed in any plane or angle (excluding D-suffix models) without compromising structural integrity.
• High Capacity: Supports up to 250,000 BTU/hr, providing the throughput necessary for mid-sized commercial and residential appliances.

Can the RV48L-3/4-48 be installed outdoors?
While the aluminum die-cast body is durable, the integral vent limiter is intended for indoor use. For outdoor applications exposed to the elements, a 13A15 vent protector must be utilized to prevent moisture and debris from entering the breather hole.

Is this regulator compatible with Propane (LP) systems?
Yes, this model is rated for use with natural, manufactured, mixed, and liquefied petroleum (LP) gases, as well as LP gas-air mixtures.

What is the purpose of the 4-8"wc spring range?
This specific spring provides a calibrated outlet pressure range of 4 to 8 inches water column, allowing technicians to fine-tune the delivery pressure to meet the specific requirements of the downstream appliance manifold.
