Maxitrol R500-3/4 Regulator

The Maxitrol R500-3/4 Regulator is a specialized appliance gas regulator engineered for high-precision pressure management in industrial and commercial environments. Standardized with 3/4 inch NPT threaded ports, this unit features a double diaphragm balanced valve design, which is critical for maintaining a stable 3-6" w.c. outlet pressure regardless of fluctuating inlet conditions. While CSA certified for 1/2 PSI, it is Maxitrol tested to handle a 1 PSI maximum inlet pressure, making it the preferred choice for infrared heaters, pilot lines on large process boilers, and industrial baking ovens.

For the veteran technician, the balanced valve construction effectively eliminates the inlet pressure effect, ensuring the gas pressure regulation remains linear across the entire flow range. The rugged aluminum die-cast housing and corrosion-resistant internal components provide reliable service in ambient temperatures ranging from -40°F to 205°F. Note that the R-series is a non-lockup regulator and is not designed for dead-end service. It is optimized for main burner and pilot load applications where continuous, steady flow is paramount for burner efficiency.

• Precise Pressure Control: The double diaphragm design compensates for varying supply pressures to prevent burner flame-out.
• Versatile Gas Compatibility: Engineered for use with natural gas, LP, and mixed gas systems.
• Industrial Durability: Rugged aluminum construction with high-quality synthetic rubber diaphragms for extreme temperature environments.
• Compact Footprint: Large capacity flow characteristics in a small frame, ideal for tight commercial burner manifolds.

• Can this be used for dead-end lockup applications? No, the R500 is a non-lockup regulator and should not be used in systems where 100% shutoff is required at the regulator.
• Is this regulator multi-positional? Yes, it is suitable for multi-positional mounting, but if a vent limiting device is installed, it must be mounted in an upright position.
• What is the maximum emergency exposure? This model has an emergency exposure limit of 2.0 PSI.
