Maxitrol R9110-25 Plated Spring

The Maxitrol R9110-25 Plated Spring is a critical replacement component for field technicians servicing Maxitrol gas regulators. Specifically engineered for use with the RV91, 210E, and 325-9 Series, this calibrated spring provides a precise outlet pressure range of 2" to 5" w.c. (water column). Maintaining the correct gas regulator spring tension is essential for stable downstream pressure and optimized burner performance in industrial and commercial combustion systems. The plated finish offers enhanced resistance to environmental fatigue, ensuring long-term reliability in high-cycle applications.

When performing a regulator spring conversion or routine maintenance, selecting the R9110-25 ensures OEM-level compatibility and performance. This 4-15/16 inch spring is designed for easy installation within the regulator stack, allowing for accurate fine-tuning of gas delivery. Utilizing a genuine Maxitrol R9110-25 helps prevent common issues such as fluttering or inconsistent lock-up pressure, keeping your HVAC infrastructure compliant and operational.

• Specifically calibrated for the Maxitrol 325-9, 210E, and RV91 series for a perfect fit.
• Supports a reliable 2-5" water column pressure range for low-pressure gas systems.
• Durable plated construction stands up to demanding mechanical stress without losing tension.
• OEM pressure control component ensures accurate modulation and safety in combustion assemblies.

Is the R9110-25 compatible with other Maxitrol series?
This specific part is engineered for the RV91, 210E, and 325-9 series. Always verify your regulator model number before swapping springs to ensure the diaphragm can handle the spring rate.

How do I identify the pressure range of this spring in the field?
The R9110-25 is identified by its plated metal appearance and length, though technical documentation should be referenced to confirm it matches the 2" to 5" w.c. specification required for your specific manifold pressure.

Can I use this spring to convert a regulator from high pressure to low pressure?
Yes, if your regulator body (like the RV210E) is rated for it, replacing a higher-tension spring with the R9110-25 allows you to achieve a stable 2-5" w.c. outlet pressure.
