Maxitrol 210GZ-3 Regulator

The Maxitrol 210GZ-3 is a high-capacity 3-inch NPT gas regulator engineered for precision fuel-air ratio control in industrial and commercial combustion systems. Utilizing a zero governor balanced valve design, this unit excels in maintaining a consistent delivery pressure despite fluctuating inlet pressures, making it a critical component for pre-mix burners and atmospheric configurations. Rated for a 5 PSI maximum inlet pressure, the 210GZ-3 provides a precise -1.0 to 1.5" w.c. outlet pressure range, ensuring optimal stoichiometric combustion. Built with high-strength aluminum castings and durable internal components, it is specifically designed for commercial gas pressure regulation of natural, manufactured, mixed gases, and LP gas-air mixtures. For technicians performing HVAC gas regulator replacement, the 210GZ-3 offers reliable lock-up characteristics and high flow rates, meeting the rigorous demands of industrial gas system components in heavy-duty heating applications.

• Precise Zero Governor Control: Maintains secondary pressure at or near atmospheric levels for accurate air-gas mixing.
• Balanced Valve Construction: Eliminates the effects of inlet pressure variations on the seating force and control accuracy.
• High Flow Capacity: Large 3" NPT ports accommodate high-demand industrial burners without significant pressure drops.
• Rugged Build Quality: Industrial-grade housing and internal components withstand the harsh environments of mechanical rooms.
• Versatile Mounting: Designed for horizontal or vertical installation while maintaining calibration sensitivity.

What is the primary application for a zero governor like the 210GZ-3?
Zero governors are typically used in pre-mix burner systems where the gas must be delivered at atmospheric pressure to be drawn in by the air flow, ensuring a consistent fuel-to-air ratio across different firing rates.

Can the Maxitrol 210GZ-3 handle propane?
Yes, this regulator is compatible with natural gas, LPG, and air-gas mixtures. Always verify specific gravity and flow requirements for your specific fuel type during installation.

Is an external vent line required for this regulator?
Standard practice for 3-inch industrial regulators involves piping the vent to a safe outdoor location to comply with local mechanical codes and ensure safety in the event of diaphragm rupture.
