Maxitrol R8110-512 Spring

The Maxitrol R8110-512 spring is a critical calibration component designed specifically for the RV81 and RV210D series gas pressure regulators. Engineered for precision gas train management, this blue adjustment spring allows for an outlet pressure range of 5 to 12 inches Water Column (WC). For service technicians and mechanical contractors, maintaining the correct manifold pressure is essential for burner efficiency and appliance safety. This spring facilitates accurate field-conversion or set-point adjustment for commercial gas regulators, ensuring consistent delivery pressures despite fluctuating supply conditions. Manufactured with high-tensile materials, it resists fatigue under high-cycle industrial applications. When performing a Maxitrol spring replacement, ensure the regulator vent is unobstructed and verify the stack height matches the existing housing to prevent mechanical binding. This HVAC replacement part is the standard specification for mid-range pressure delivery in modulating gas systems and fixed-orifice burners.

• Precise Pressure Control: Enables a stable 5-12" WC pressure range for varied gas regulator settings.
• OEM Compatibility: Specifically engineered for Maxitrol RV81 and RV210D series housings to ensure linear compression rates.
• Simplified Identification: Color-coded blue for rapid field verification of the spring range and pressure rating.
• Industrial Durability: Designed for long-term set-point stability in high-demand gas-fired equipment.

Can this spring be used to convert a regulator from Natural Gas to Propane?
Yes, provided the target outlet pressure falls within the 5-12" WC range. Always verify the regulator's maximum inlet pressure rating and orifice capacity before performing a gas conversion.

Is the R8110-512 compatible with other RV series regulators?
No, this specific spring is sized for the 81 and 210D series. Using this spring in smaller or larger regulator bodies will result in inaccurate calibration and potential equipment failure.

What is the significance of the blue color coding?
The blue finish indicates the Maxitrol spring chart specification for mid-range pressure (5-12" WC), distinguishing it from the silver (low-pressure) or red (high-pressure) variants.
