Maxitrol R11110-512 Spring

Working in the field, you know that precise outlet pressure is the difference between a high-efficiency burn and a service call. The Maxitrol R11110-512 Blue Spring is a critical component for field-calibrating Maxitrol gas pressure regulators within the RV110, RV111, and 210G Series. Designed for reliability in high-capacity industrial and commercial gas systems, this 5-12" W.C. regulator spring provides the necessary tension to maintain stable delivery pressures even under varying inlet conditions. This factory-calibrated blue spring is approximately 8-1/8 inches in length and features a plated finish for superior corrosion resistance and longevity within the regulator housing. Whether you are performing a regulator spring replacement to adjust for specific appliance requirements or conducting routine maintenance on a straight-thru-flow regulator, using the correct OEM-spec Maxitrol R11110-512 ensures the assembly meets its original 1/2 PSI rated pressure performance standards without the need for entire valve replacement.

• Precise Pressure Range: Calibrated specifically for a 5 to 12 inches water column (W.C.) outlet range, facilitating accurate tuning for diverse burner requirements.
• Enhanced Compatibility: Direct fit for high-capacity RV110, RV111, and 210G Series regulators often found in industrial boiler and furnace applications.
• Heavy-Duty Construction: The plated steel spring design prevents oxidation and fatigue, maintaining set point stability over time.
• Standardized Identification: The blue color code allows for rapid visual identification in the field, reducing errors during multi-stage regulator service.

How do I know if the R11110-512 is the right spring for my regulator?
This spring is exclusively designed for the larger Maxitrol RV110, RV111, and 210G bodies. Check your regulator’s data plate; if the model matches these series and you need an outlet pressure between 5" and 12" W.C., this is the correct blue-coded component.

Can this spring be used for both Natural Gas and Propane applications?
Yes, as long as the regulator itself is rated for the gas type and the desired outlet pressure falls within the 5-12" W.C. range. Always verify the total BTU capacity of the system when changing spring ranges.

Does this spring include the regulator adjustment cap?
No, the R11110-512 consists of the calibrated spring only. You should reuse your existing adjustment screw and gasket or source them separately if they are damaged.
