Maxitrol R500-1/2 Regulator

The Maxitrol R500-1/2 Regulator is a specialized gas appliance pressure regulator designed for high-performance stability in residential and commercial heating systems. Featuring a double diaphragm balanced valve design, this unit maintains a consistent outlet pressure even when subjected to fluctuating inlet pressures, ensuring reliable performance for both main burner and pilot load applications. With 1/2" NPT threaded connections and a 1 PSI maximum inlet pressure rating, the R500-1/2 is engineered for precision within the 3-8" w.c. outlet pressure range. Its compact aluminum housing is ideal for space-constrained installations, and it's built to handle natural gas, propane, and LP gas-air mixtures. This regulator is a standard choice for infrared heaters and pilot lines on industrial boilers where steady gas flow is critical for efficiency and safety.

• Double Diaphragm Technology: Provides superior balanced valve performance, isolating the outlet pressure from inlet variations.
• Versatile Mounting: Supports multi-positional mounting, allowing for flexible configuration within various HVACR setups.
• Broad Compatibility: Rated for a temperature range of -40°F to 205°F, making it suitable for demanding thermal environments.
• Exceptional Flow Capacity: Despite its small footprint, it delivers high volume throughput for large industrial applications.

What gas types are compatible with the Maxitrol R500-1/2?
This regulator is professionally rated for use with natural gas, manufactured gas, mixed gases, liquefied petroleum (LP) gases, and LP gas-air mixtures.

Can this regulator handle 2 PSI inlet pressure?
No. While it has an emergency exposure limit of 2 PSI, the Maxitrol tested maximum inlet pressure for safe operation is 1 PSI. Exceeding this can lead to equipment failure.

Does the R500-1/2 support dead-end lockup service?
The R series is not intended for dead-end lockup. It should be used in applications where steady outlet pressure is required during active burner or pilot operation.
