Maxitrol R8110-515 Green Spring

The Maxitrol R8110-515 is a high-precision green spring specifically engineered for gas pressure regulators in the RV81 and 210D series. Designed for professional HVACR applications, this component allows technicians to achieve an outlet pressure range of 5-15" w.c. (Water Column), ensuring stable and consistent fuel delivery to high-capacity burners. As a straight-thru-flow regulator accessory, it supports the Maxitrol RV81-1-1/4 and RV81-1-1/2 models, as well as 210D balanced valve regulators, maintaining the accuracy required for industrial and commercial gas-fired equipment. By replacing standard springs with this 5-15" wc green spring, contractors can precisely calibrate gas control assemblies to meet specific system demands, optimizing combustion efficiency across natural, manufactured, and LP gas types. This durable replacement regulator spring is essential for maintaining proper tension and ensuring reliable operation in systems with changing load conditions.

• Specifically calibrated for an outlet pressure range of 5-15" w.c. to meet high-pressure HVACR requirements.
• Full compatibility with Maxitrol RV81 and 210D series appliance regulators found in commercial gas systems.
• Optimized for straight-thru-flow (STF) designs, ensuring minimal pressure drop and accurate regulation.
• Durable green-coded construction for immediate identification and reliable spring rate performance.
• Facilitates precise field adjustments for gas pressure regulation in complex industrial heating applications.

What regulator models are compatible with the R8110-515 green spring?
This spring is designed exclusively for the Maxitrol RV81 and 210D series regulators. It is commonly used in 1-1/4" and 1-1/2" NPT pipe size installations where higher outlet pressures are required.

How do I identify the pressure range of this Maxitrol spring?
The green color coding signifies a 5" to 15" water column range for the RV81/210D series. Always verify the color against the Maxitrol spring selection chart to ensure it meets the appliance’s manifold pressure requirements.

Can this spring be used with both Natural Gas and Propane (LP)?
Yes, the Maxitrol R8110-515 is suitable for use in systems involving natural, manufactured, mixed, and liquefied petroleum (LP) gases, provided the regulator itself is rated for the specific gas type.
