Maxitrol 210D-1 1/4 Regulator

The Maxitrol 210D-1 1/4 Regulator is a high-capacity, lock-up style gas regulator engineered for industrial-grade performance in high-demand systems like boilers, steam generators, and large-scale furnaces. Featuring a balanced valve design, this 1 1/4" NPT gas regulator maintains precise downstream pressure control even when inlet pressures fluctuate. It supports a 10 PSI maximum inlet pressure and comes factory-set for a 3-8" w.c. outlet pressure range, effectively eliminating "hunting" or pressure creep through integrated dampening mechanisms in the breather outlet and sensing tube. This industrial gas pressure regulator is compatible with natural gas, propane (LP), and mixed fuel gases, providing stable regulation from full flow down to pilot flow for critical combustion equipment. Designed for upright installation in horizontal pipe runs, the 210D series is the go-to choice for contractors requiring high flow capacity and reliable dead-end lock-up performance in demanding HVACR and industrial environments.

• Precise Pressure Control: The balanced valve construction negates the effect of inlet pressure variations, ensuring steady output.
• Industrial Durability: Constructed with high-strength aluminum alloy housings and corrosion-resistant internal components.
• Broad Operating Range: Capable of managing ambient temperatures from -40°F to 200°F, suitable for diverse mechanical room conditions.
• System Stability: Internal sensing tubes and breather dampeners reduce oscillation and improve overall combustion efficiency.

What is the purpose of the lock-up style design?

In the 210D series, the lock-up feature ensures that the regulator provides a bubble-tight shut-off when there is no flow, preventing high-pressure gas from creeping into downstream components during idle periods.

Can this regulator be used with propane?

Yes, this unit is fully compatible with natural, manufactured, mixed, and liquefied petroleum (LP) gases, making it a versatile solution for varied fuel sources.

Does it require a vent protector for outdoor use?

For outdoor installations, an optional 13A15-5 vent protector should be utilized to protect the breather hole from debris and moisture, ensuring consistent diaphragm response.
