Maxitrol 220D-1 1/2 Regulator

The Maxitrol 220D-1 1/2" Gas Pressure Regulator is a specialized servo-operated pilot loaded gas regulator designed for high-capacity industrial and commercial applications requiring precise delivery pressures. Engineered with a 1-1/2" NPT connection, this unit manages a 10 PSI maximum inlet pressure while maintaining a highly stable 1-3 PSI outlet pressure range facilitated by the R325C10-1022 spring. Unlike standard direct-acting regulators, the pilot-loaded design provides superior droop characteristics, ensuring a consistent 6,500,000 BTU/hr capacity across varying flow rates. This industrial gas pressure regulator is ideal for large-scale boilers, furnaces, and manifold systems where pressure stability is critical for combustion efficiency. Built with cast iron or aluminum housing for long-term field durability, it is a Made in the USA component that meets rigorous gas system piping standards for natural gas and propane (LP) applications.

Key Benefits for HVACR Professionals:

• Precision Pilot Control: Utilizes a servo-operated pilot-loaded design to eliminate pressure fluctuations common in high-flow gas banks.
• High BTU Output: Supports massive loads up to 6,500,000 BTU, making it the standard for commercial heating plant upgrades.
• Robust Pressure Management: Handles a 10 PSI max inlet, allowing it to function effectively as a secondary stage regulator in high-distribution lines.
• Consistent Performance: The pre-installed 1-3 PSI outlet spring ensures accurate calibration for equipment requiring higher-than-standard delivery pressures.

Common Questions:

Can the Maxitrol 220D be mounted in any orientation?
For peak accuracy and to prevent debris from fouling the pilot assembly, it is professionally recommended to install the regulator in a horizontal pipe run with the vent pointed downwards.

What is the lockup pressure rating for this model?
As a high-capacity gas regulator, the 220D series features excellent lockup characteristics, but for safety in confined spaces, vent limiting or external venting should be installed according to local mechanical codes.

Is this regulator compatible with LPG?
Yes, this unit is suitable for natural, manufactured, mixed, liquefied petroleum gases, and LP gas-air mixtures.
