Maxitrol R9110-1022 Spring

The Maxitrol R9110-1022 is a high-performance red regulator spring engineered for precise pressure management in commercial and industrial gas systems. Designed specifically for the Maxitrol RV91, RV210E, and 325-9 Series regulators, this heavy-duty spring provides a consistent outlet pressure range of 10 to 22 inches Water Column (WC). As a critical component for gas pressure regulation, it ensures the stable delivery of fuel to high-capacity appliances such as boilers, furnaces, and large-scale water heaters.

This replacement regulator spring features a robust 1-1/8 inch inner diameter and a 5-5/8 inch length, facilitating a direct fit into the regulator’s top cover assembly. Technicians rely on the Maxitrol R9110-1022 for its calibrated tension, which prevents hunting and maintains steady downstream gas pressure even during high-demand cycles. Whether you are performing routine maintenance or converting a line pressure regulator to a higher output setting, this 10-22" WC spring offers the mechanical reliability required for tight HVACR gas control configurations. Built to withstand continuous duty, it is the standard choice for contractors managing Maxitrol 325-9 systems and RV series poppet regulators.

• Compatible with Maxitrol RV91, RV210E, and 325-9 series regulators.
• Provides a dependable 10-22" WC outlet pressure range for high-demand applications.
• Color-coded red for immediate field identification and error-free installation.
• Engineered for straight-thru-flow and balanced valve regulator designs to ensure sensitive regulation.
• Industrial-grade construction maintains calibration under variable inlet pressure conditions.

• Can this spring be used in a 325-7 regulator? No, the R9110-1022 is specifically dimensioned for the larger 325-9, RV91, and 210E series; the 325-7 series typically utilizes the R8110 series springs.
• What is the purpose of the red color coding? Maxitrol uses color-coded springs to signify specific pressure ranges; red indicates the 10" to 22" Water Column range for these specific regulator footprints.
• Is professional calibration required after installation? Yes, after replacing a regulator spring, always use a manometer to verify the outlet pressure and adjust the regulator stack to the specific appliance requirements.
