Maxitrol 220J-4 Regulator

The Maxitrol 220J-4 Regulator is a high-capacity industrial solution engineered for heavy-duty applications such as industrial furnaces and large-scale ovens. Unlike standard spring-loaded models, this 4-inch 125# flange gas regulator utilizes a servo-operated pilot loaded design. This advanced gas pressure control architecture loads the main diaphragm with gas pressure instead of a mechanical spring, allowing for significantly higher outlet pressures and exceptional accuracy across a broad flow range up to 50,000 CFH. Designed for versatility, it is compatible with natural gas, LP gas, and mixed fuel gases, maintaining precise regulation even in demanding environments with ambient temperature limits from -40°F to 200°F.

For optimal performance, the Maxitrol 220J-4 must be installed in an upright position within a horizontal pipe run. The integrated pilot regulator in the upper housing allows for seamless adjustments to the 1-3 PSI outlet pressure; simply remove the hood and adjust the pilot setting to change the main regulator output proportionately. With a 10 PSI maximum inlet pressure and an emergency exposure limit of 25 PSI, this unit provides the rugged reliability required for industrial gas piping systems. The 4-bolt flange connection ensures a secure, leak-resistant interface for high-volume manifolds.

• Servo-Operated Precision: Pilot-loaded design delivers superior accuracy and higher outlet pressures than traditional spring-loaded regulators.
• High-Volume Capacity: Supports flow rates up to 50,000 CFH, making it ideal for industrial-scale gas manifolds.
• Rugged Aluminum Construction: Lightweight yet durable housing designed to withstand harsh mechanical rooms and industrial environments.
• Flexible Monitoring: Features multiple tap positions that can be plugged or used for taking critical inlet and outlet pressure readings.
• Universal Fuel Compatibility: Internally rated for natural, manufactured, mixed, and liquefied petroleum gases.

• What is the proper mounting orientation for this regulator? This unit must be mounted in an upright position on a horizontal pipe run to ensure the servo-pilot functions correctly.
• Can this regulator be used for remote sensing? Yes, the 220 series design allows for remote sensing configurations to monitor pressure at a specific point downstream from the unit.
• Does this model include a vent limiting device? The 220J-4 typically utilizes a single vent equipped with a vent limiting orifice; however, always consult local codes regarding indoor venting requirements.
