Maxitrol R500S-1/2 Regulator

The Maxitrol R500S-1/2 is a high-performance gas appliance regulator designed for both main burner and pilot load applications. Featuring a double diaphragm balanced valve design, this regulator excel in maintaining a steady 3-6"wc outlet pressure even when subjected to widely varying inlet pressures. With a 1/2" NPT connection and a 5 PSI max inlet pressure rating (Maxitrol tested), it is an ideal choice for infrared heaters, industrial boilers, and pilot lines where precise control is non-negotiable. The aluminum housing and compact footprint allow for multi-positional mounting, making it a versatile component for field replacements and new installations alike. It is fully compatible with natural gas, LP, and mixed gas systems, ensuring reliable lockup-type regulation across demanding HVACR environments.

• Double Diaphragm Technology: Provides superior stability and eliminates inlet pressure effects for consistent downstream performance.
• High Capacity, Small Footprint: Engineered to handle significant flow rates without requiring the space of larger industrial regulators.
• Multi-Positional Installation: Can be mounted in various orientations, though an upright position is required if utilizing a ball check vent limiter.
• Broad Compatibility: Suitable for use with liquefied petroleum gases, manufactured gases, and LP gas-air mixtures.
• Rugged Aluminum Construction: Delivers long-term durability in ambient temperature ranges from -40° to 205°F.

Can this regulator be used for both Natural Gas and Propane?
Yes, the R500S-1/2 is rated for Natural Gas and LP gas applications, provided the spring range meets your specific appliance requirements.

What does the 'S' designate in the R500S model?
The 'S' indicates a Straight-Thru-Flow design specifically tested by Maxitrol to handle up to 5 PSI max inlet pressure, compared to the standard 1 PSI rating of the base R500 model.

Is a vent limiter included with this unit?
Standard units typically require a separate 12A04 vent limiter if local codes mandate one; always verify your specific installation requirements before completing the gas train.
