Maxitrol R600-3/4-CSA Regulator

The Maxitrol R600-3/4-CSA is a high-performance gas appliance pressure regulator designed for both main burner and pilot load applications. Featuring a double diaphragm balanced valve design, this 3/4" NPT regulator maintains a steady outlet pressure even when subjected to widely varying inlet pressures. It is CSA certified for a 1/2 PSI maximum inlet pressure, though it has been Maxitrol tested up to 1 PSI for robust field performance. The pre-installed spring provides an adjustable 3-6" w.c. outlet pressure range, making it ideal for natural gas, LP, and mixed gas systems in commercial or industrial settings. Built with a rugged aluminum die-cast housing and corrosion-resistant internal components, the Maxitrol R600 ensures reliable gas flow control for infrared heaters, boilers, and other high-capacity equipment. Its compact footprint allows for multi-positional mounting, simplifying installation in tight mechanical spaces while providing superior lockup-type regulation for demanding HVACR projects.

• Double Diaphragm Construction: Provides superior pressure regulation and eliminates inlet pressure effects for consistent appliance performance.
• Versatile Fuel Compatibility: Rated for use with natural gas, manufactured, mixed, and liquefied petroleum (LP) gases.
• Wide Temperature Range: Reliable operation in extreme environments, rated from -40°F to 205°F.
• Compact Multi-Positional Mounting: Small swing radius and aluminum housing allow for flexible gas regulator installation in various orientations.
• High Capacity Design: Specifically engineered to handle both high-demand main burners and low-flow pilot applications without losing control.

Can this regulator be used for 2 PSI piping systems?
No, the Maxitrol R600-3/4-CSA is a low-pressure appliance regulator. For 2 PSI or 5 PSI systems, a 325 series line regulator is required. This model is CSA certified for 1/2 PSI Max Inlet Pressure.

Does this model support dead-end lockup?
Yes, the R600 series features a balanced valve design that is suitable for applications requiring lockup, though it should not be used as a primary line regulator for appliances with electronic ignition unless the valve can open against line pressure.

What is the proper mounting orientation for the vent?
While the regulator is suitable for multi-positional mounting, if a vent limiting device is installed, it must be mounted in an upright position to ensure the ball check functions correctly.
