Maxitrol R9110-48 Spring

The Maxitrol R9110-48 is a job-site essential for calibrating gas pressure regulators to specific field requirements. This orange replacement spring is precision-engineered to provide an outlet pressure range of 4-8" W.C. (Water Column), ensuring stable manifold pressure for downstream components. Designed specifically for the Maxitrol RV91 and Maxitrol 210E series, this OEM-grade component maintains the Straight-Thru-Flow (STF) performance characteristics these regulators are known for. Utilizing a high-performance regulator spring is critical for technicians performing gas valve pressure adjustments or converting appliances for different fuel profiles. The color-coded orange finish allows for immediate identification in the van or during inspection, reducing service time and preventing installation errors. Built from high-tensile spring steel, the R9110-48 provides consistent tension and reset accuracy across standard HVAC operating temperatures, ensuring the RV91/210E series delivers the sensitive regulation required for high-capacity commercial and industrial gas-fired equipment.

Key Benefits

• Direct Compatibility: Engineered as a drop-in replacement for RV91 Series and 210E Series regulators.
• Precise Calibration: Reliably maintains a 4-8" W.C. discharge range for stable appliance operation.
• Field Efficiency: Orange color-coding ensures rapid identification of the pressure range during maintenance rounds.
• Industrial Durability: Constructed to withstand the cycling demands of commercial gas pressure regulation systems.
• Performance Integrity: Supports the Straight-Thru-Flow design to minimize frictional resistance and maximize flow capacity.

Common Questions

Can the R9110-48 be used with LP (Liquid Propane) gas?
Yes, this spring is compatible with RV91 and 210E regulators used in Natural, Manufactured, Mixed, and Liquefied Petroleum (LP) gas applications, provided the desired outlet pressure falls within the 4-8" W.C. range.

How do I identify the correct Maxitrol spring for my regulator?
Selection is based on the regulator model number and the required outlet pressure. The R9110 series is specific to the RV91 and 210E; the orange finish specifically designates the 4-8" W.C. tension profile.

Does this spring fit the RV52 or RV61 series regulators?
No, those series require different spring diameters. The Maxitrol R9110-48 is sized exclusively for the larger RV91 and 210E housings.
