Maxitrol R8110-412 Spring

Ensure reliable gas pressure regulation with the Maxitrol R8110-412, a precision-engineered violet range spring designed for field-proven performance. This replacement regulator spring is specifically calibrated to provide a consistent outlet pressure range of 4 to 12 inches Water Column (W.C.), making it a critical component for fine-tuning gas flow in commercial and industrial environments. Built to integrate seamlessly with the Maxitrol RV81, 210D series, and 325-7A series regulators, this spring allows technicians to meet exact manifold pressure requirements for various high-capacity appliances.

The Maxitrol R8110-412 is manufactured with high-tensile alloy to maintain its tension and calibration over long service intervals, preventing pressure drift that can compromise burner efficiency. Whether you are performing a seasonal conversion or replacing a fatigued gas pressure regulator spring, this violet-coded component ensures your RV81/210D/325-7A series equipment operates within the specified 4-12" W.C. parameters. Proper installation by a licensed contractor is recommended to verify output using a manometer, ensuring safe and optimal gas regulator performance across natural gas or LP applications.

• Precise Pressure Calibration: Specifically engineered to deliver a 4" to 12" W.C. range for accurate gas appliance manifold settings.
• Broad Series Compatibility: Direct-fit replacement for Maxitrol RV81, 210D, and 325-7A series gas regulators.
• Violet Color Coding: Permanent color-coded identification ensures quick field verification and prevents installation of incorrect pressure ranges.
• Industrial-Grade Resilience: High-quality construction maintains structural integrity under fluctuating demand and ambient temperature cycles.

What is the standard application for the violet spring 4-12" W.C.?
This spring is typically used in applications requiring higher outlet pressures than standard residential settings, often found in commercial kitchens or industrial heating units where 4-12" W.C. is required for proper burner ignition and operation.

Can I use this spring in a Maxitrol 325-3 regulator?
No, the R8110-412 is sized specifically for the larger RV81, 210D, and 325-7A series bodies. Utilizing this spring in a 325-3 or 325-5 series regulator will lead to improper seating and incorrect pressure regulation.

Is this spring compatible with both natural gas and LP systems?
Yes, provided the regulator itself is rated for the gas type. The spring functions based on mechanical tension and is suitable for use in systems regulating natural, manufactured, mixed, or liquefied petroleum gases.
