Maxitrol 220G-3 Regulator

The Maxitrol 220G-3 is a high-capacity, 3" NPT gas pressure regulator engineered for demanding commercial and industrial applications like large-scale furnaces and boilers. Utilizing a servo-operated pilot loaded design, this model provides superior precision and higher outlet pressures than standard spring-loaded alternatives. The main diaphragm is controlled by gas pressure from a dedicated pilot regulator in the upper housing, ensuring stable performance across its 10 PSI maximum inlet pressure rating. With a robust 50,000,000 BTU capacity and an adjustable outlet range of 1-3 PSI, the 220G-3 maintains consistent delivery even in high-flow environments. This industrial gas regulator is suitable for natural, manufactured, mixed, and liquefied petroleum gases. Technicians should note that for optimal accuracy and to allow the vent limiter to function correctly, this unit must be installed in an upright position on a horizontal pipe run. The durable aluminum housing and Maxitrol servo regulator technology make it a standard choice for contractors requiring reliable gas pressure control in heavy-duty HVACR systems.

• High Flow Precision: Servo-operated design eliminates the "droop" common in spring-loaded regulators, maintaining 1-3 PSI outlet accuracy even at high capacities.
• Versatile Fuel Compatibility: Fully rated for use with Natural Gas, LP, and LP-air mixtures, providing flexibility for diverse job site requirements.
• Massive Capacity: Supports up to 50,000,000 BTU/hr, making it ideal for large manifold systems and industrial process heating.
• Rugged Construction: Built with a durable aluminum body and high-grade 3 inch NPT threads to withstand the rigors of mechanical room environments.
• Simplified Maintenance: Features accessible pressure taps for quick inlet and outlet readings during commissioning and diagnostic checks.

Common Questions What is the maximum emergency exposure pressure for the 220G-3? The regulator can withstand an emergency exposure of up to 25 PSI without internal damage, though regulation accuracy is only maintained up to the 10 PSI inlet rating. Can this regulator be mounted in a vertical pipe run? For proper operation of the pilot assembly and vent limiting orifice, the 220G-3 must be mounted in an upright position on a horizontal pipe run with the flow arrow oriented correctly. Does this model include internal relief? No, the 220 series typically does not contain internal relief. Installers must ensure the system meets local codes regarding overpressure protection and proper venting to the outdoors.
