Maxitrol R9110-515 Spring

Technicians working with Maxitrol RV91 or Maxitrol 210E Series regulators know that precise manifold pressure is non-negotiable for high-capacity gas-fired equipment. The Maxitrol R9110-515 is a professional-grade 5-15" WC green spring engineered to provide accurate pressure regulation in systems requiring mid-to-high water column settings. This OEM replacement spring is specifically designed for balanced valve regulators used in industrial furnaces, steam generators, and large-scale boilers where stable fuel delivery is critical for efficient combustion.

Constructed from high-tensile, corrosion-resistant materials, the R9110-515 green spring ensures consistent performance under varying load conditions. When performing a regulator spring conversion or routine maintenance, this part offers the exact tension needed to hit your target outlet pressure range without the drifting common in aftermarket alternatives. Its color-coded green design allows for instant identification in the field, reducing errors during installation in direct-acting gas regulators.

• Precise Pressure Control: Specifically calibrated for a 5" to 15" water column range to meet demanding industrial specifications.
• OEM Compatibility: Guaranteed fit for Maxitrol RV91 and Maxitrol 210E series, ensuring the regulator maintains its original flow characteristics.
• Industrial Durability: Built to withstand the high-cycle demands of modulation in commercial gas valve assemblies.
• Field Identification: Standardized green color coding simplifies inventory management and technical verification on the job site.

Can I use this spring in an RV61 or RV81 regulator?
No, the R9110-515 is specifically engineered for the larger RV91 and 210E series housings. Check your specific Maxitrol spring selection chart to ensure the physical dimensions match your regulator's internal tower.

What happens if I need an outlet pressure higher than 15" WC?
If your application requires pressures exceeding the 15" WC limit of the green spring, you must step up to the red (10-22" WC) or yellow (15-30" WC) springs. Never over-compress a spring to achieve pressures outside its rated WC range.

Is this spring suitable for LP gas applications?
Yes, this Maxitrol regulator spring is compatible with natural, manufactured, mixed, and liquefied petroleum (LP) gases, provided the regulator itself is rated for the specific gas type and inlet pressure.
