Maxitrol R11110-412 Spring

The Maxitrol R11110-412 is a precision-engineered violet spring designed for field-service adjustments and pressure recalibration of RV110, RV111, and 210G Series gas pressure regulators. As a critical component for maintaining precise downstream pressure, this spring allows technicians to set a stable outlet pressure range of 4-12" w.c. (water column). Its 7-3/8" length and plated construction ensure consistent tension and corrosion resistance in light commercial and residential gas piping systems, including those handling natural, manufactured, or LP gases.

When swapping springs in a Maxitrol gas regulator, verifying compatibility with the specific poppet design or balanced valve design of the 210G series is vital for preventing hunting or insufficient flow. This replacement regulator spring is color-coded violet for rapid identification during routine maintenance or HVAC pressure adjustment tasks. By utilizing this OEM-spec component, contractors can ensure their Maxitrol RV111 or RV110 units perform to original factory flow capacities without compromising the straight-thru-flow efficiency required for high-demand burners.

• Precise Pressure Control: Delivers a calibrated 4-12 inches water column range for medium-pressure gas applications.
• Direct Compatibility: Engineered specifically for the Maxitrol RV110, RV111, and 210G regulator families.
• Durable Plated Finish: The violet color-coded plating protects against environmental fatigue and simplifies part identification in the field.
• Optimized Regulator Response: Maintains the intended spring rate to prevent pressure spikes or pilot drop-outs.

• Can this spring be used in the 325-3 series? No, this spring is specifically for the RV110/111 and 210G series; different series require different spring diameters and lengths such as the R325 series.
• How do I identify the current pressure range? Maxitrol uses a color-coding system; if your current spring is violet, it likely corresponds to this 4-12" w.c. range.
• What gases is this spring compatible with? It is suitable for use in systems running natural, liquefied petroleum (LP), or air-gas mixtures when installed in the appropriate Maxitrol regulator.
