Maxitrol 220E-2 Regulator

The Maxitrol 220E-2 is a high-capacity, 2" NPT gas pressure regulator explicitly engineered for industrial applications such as furnaces and ovens. Utilizing a servo-operated pilot loaded design, this unit offers a distinct performance advantage over standard spring-loaded models by delivering higher outlet pressures and more precise control. The servo-operated gas regulator mechanism uses gas pressure to load the main diaphragm, regulated by a secondary pilot regulator in the upper housing, ensuring the 1-3 PSI outlet pressure remains stable even under varying demand. With a 10 PSI maximum inlet pressure and a massive 12,000,000 BTU capacity, this regulator is the standard for high-volume industrial gas pressure regulation. Built with a rugged aluminum housing, it supports multiple fuel types, including natural gas, LP, and mixed gases. For optimal accuracy and safety, always install the unit in an upright position on a horizontal pipe run and verify that the 12A06 vent limiting orifice is properly seated in the upper housing.

• Enhanced Pressure Stability: The pilot-loaded design eliminates the "droop" typically found in spring-loaded regulators, maintaining consistent pressure across the entire flow range.
• Industrial High-Flow Performance: Capable of handling up to 50,000 CFH, making it ideal for large-scale boiler and furnace manifolds.
• Precision Field Adjustments: Easily adjust outlet pressure by modifying the pilot regulator spring, allowing for proportional changes to the main line pressure.
• Versatile Fuel Compatibility: Engineered for use with natural gas, propane, and LP gas-air mixtures in demanding commercial environments.
• Rugged Construction: Designed for an ambient temperature range of -40°F to 200°F, ensuring reliable operation in extreme mechanical room conditions.

Can the Maxitrol 220E-2 be mounted in any orientation?
No. For proper servo function and accurate regulation, this regulator must be mounted in an upright position on a horizontal pipe run with the flow following the directional arrow on the body.

What happens if the inlet pressure exceeds the 10 PSI rating?
While the maximum operating inlet is 10 PSI, the unit has an emergency exposure limit of 25 PSI. Exceeding this limit can cause internal damage, though it is designed to prevent external leakage up to that point.

Does this regulator require a separate vent line?
The 220E-2 comes equipped with a 12A06 vent limiting orifice. In many jurisdictions, this eliminates the need for a dedicated vent line to the outdoors, provided it meets local mechanical codes for fuel gas piping.
