Maxitrol R9110-36 Spring

For service professionals managing high-capacity gas lines, the Maxitrol R9110-36 is the industry-standard plated spring designed specifically for RV91 and 210E series regulators. Engineering precision in the 3-6" w.c. pressure range allows for accurate outlet pressure adjustment in commercial and industrial settings. This heavy-duty replacement gas regulator spring is built from high-tensile plated steel to resist corrosion and maintain tension across a wide temperature spectrum, ranging from -40°F to 180°F. Whether you are performing a field conversion or a scheduled regulator rebuild, the silver-colored R9110-36 ensures the straight-thru-flow performance that Maxitrol is known for. It provides the necessary mechanical force to counter the diaphragm, ensuring main burner and pilot load stability even at low inlet pressures. This part is essential for maintaining CSA certified safety standards in natural gas or LP systems where down-stream controls require consistent, low-pressure delivery.

• Precise Pressure Control: Calibrated specifically for a 3" to 6" water column range to meet exacting equipment specifications.
• Rugged Construction: Plated steel finish prevents oxidation and ensures reliable cycling in demanding HVACR environments.
• OEM Compatibility: A direct-fit replacement part for Maxitrol RV91 and 210E series gas pressure regulators.
• Wide Operating Range: Engineered for stability in extreme temperatures, making it suitable for unconditioned mechanical rooms.
• Simple Identification: The silver/plated color coding allows for rapid verification of the spring's pressure rating during service calls.

Which regulators are compatible with the R9110-36 spring?
This spring is specifically designed for the Maxitrol RV91 (including RV91-2 and RV91-2-1/2) and 210E series regulators. It is not interchangeable with smaller RV series models.

Can I use this spring for an LP gas conversion?
Yes, provided your system requires an outlet pressure within the 3-6" w.c. range. Always verify the required manifold pressure on the appliance nameplate before installation.

Does the spring color matter during a replacement?
In the Maxitrol system, color indicates the specific tension range. Replacing a silver R9110-36 with a different color (like the green R8110 or blue R9110-512) will change your available adjustment range and potentially cause unsafe operating conditions.
