Maxitrol RV48L-3/4-512 Regulator

The Maxitrol RV48L-3/4-512 is a professional-grade appliance gas regulator engineered for high-performance pressure control in commercial and residential heating systems. Featuring a 3/4 inch NPT connection, this poppet style regulator is designed with a rubber seat to ensure positive shut-off and precise regulation even at low flow rates. Field technicians rely on the RV48L series for its integral vent limiting orifice, which eliminates the need for external vent piping in most jurisdictions, streamlining the installation of gas-fired equipment like boilers, furnaces, and commercial ranges. With a maximum inlet pressure of 1/2 PSI and a factory-calibrated 5-12 inch water column outlet range, it provides the stable manifold pressure required for optimal combustion efficiency. This Maxitrol regulator is a direct solution for contractors troubleshooting gas pressure drops or inconsistent burner flames, ensuring ANSI Z21.18 compliance for localized appliance regulation.

• Internal Vent Limiting: Features a factory-installed vent limiter to bypass the need for external vent lines, saving labor and material costs.
• Precise Pressure Control: The 5-12" w.c. spring range allows for fine-tuning gas delivery to meet specific manufacturer manifold requirements.
• Durable Poppet Design: Utilizes a rubber seat poppet model for superior sealing and sensitivity to small flow changes.
• High Flow Capacity: Rated for approximately 250,000 BTU/hr, making it suitable for high-demand appliance manifolds.

Common Questions

Can this regulator be installed in any orientation?
While Maxitrol RV48L units are versatile, they should ideally be mounted horizontally to ensure the vent limiter functions correctly. Always check the flow arrow on the casting to match the direction of gas flow.

Does this unit require a separate vent line to the outdoors?
No, the integral vent limiting orifice is designed to limit the escape of gas in the event of a diaphragm rupture, typically meeting code requirements for indoor installation without external venting.

Is this regulator compatible with Propane (LP)?
Yes, this Maxitrol regulator is suitable for Natural Gas, manufactured, mixed, and LP gas applications, provided the inlet pressure does not exceed 0.5 PSI.
