Maxitrol R11110-25 Spring

When you are dealing with high-capacity gas delivery, the Maxitrol R11110-25 Spring is the professional choice for field-tuning RV110, RV111, and 210G Series Regulators. This 2-5" WC Plated Spring is specifically engineered to provide precise pressure regulation in Straight-Thru-Flow appliance regulators, ensuring the conical valve maintains an optimal flow pattern. By swapping out an existing spring for the R11110-25, you can calibrate your gas pressure regulator to a tighter 2 to 5 inches water column range, which is critical for maximizing combustion efficiency in residential and light commercial HVACR systems. The plated steel construction is designed for durability in demanding environments, resisting corrosion and maintaining consistent spring tension. For contractors servicing boiler systems or large-scale burners, utilizing the correct Maxitrol regulator spring is essential to prevent pressure drops and ensure stable outlet delivery under varying load conditions.

• Universal Series Compatibility: Engineered for seamless integration with RV110, RV111, and 210G Series housings.
• Precise Pressure Calibration: Specifically rated for a 2-5" water column range to meet strict appliance manifold specifications.
• Enhanced Flow Dynamics: Supports the Straight-Thru-Flow design to reduce frictional resistance and increase overall capacity.
• Durable Plated Finish: High-grade plating protects against moisture and gas-borne contaminants for long-term reliability.

Can the R11110-25 be used for LP gas applications?
Yes, this plated spring is suitable for natural, manufactured, mixed, and liquefied petroleum (LP) gases. When used in LP systems, ensure your total pressure drop calculations account for the specific gravity of the fuel.

What is the primary indicator that this spring is required?
If your current Maxitrol RV111 regulator is cycling or failing to maintain a stable 2-5" WC outlet pressure under load, a spring replacement is often necessary to restore factory-spec regulation.

Is this spring compatible with 210D or 210E models?
No, the R11110 high-capacity series springs are sized specifically for the larger RV111 and 210G frames and will not fit the smaller 210D or 210E regulator stacks.
