Maxitrol R5210-25 Spring

For field technicians and mechanical contractors, the Maxitrol R5210-25 is the industry-standard plated spring designed specifically for gas pressure regulator calibration. This high-precision 2-5" W.C. spring is engineered to provide stable outlet pressure regulation within a 2.0 to 5.0-inch water column range. When performing regulator spring replacement on-site, using genuine Maxitrol parts ensures the internal diaphragm responds accurately to flow fluctuations, preventing pilot drop-outs or over-firing in downstream equipment. The R5210-25 is a direct-fit internal component for the Maxitrol RV52, R500, and R500S series gas regulators. Its plated finish provides essential corrosion resistance for long-term service in commercial and industrial gas piping systems. Whether you are converting a system or fine-tuning manifold pressure, this spring maintains the required tension for consistent gas valve performance. Rely on this OEM-spec component for reliable seat-to-orifice alignment and precise set-point maintenance across various fuel gas applications.

Key Benefits for Technicians:

• Universal Compatibility: Specifically designed for seamless integration with Maxitrol RV52, R500, and R500S regulator bodies.
• Precise Pressure Range: Calibrated for a 2-5" W.C. set point, ideal for standard low-pressure gas systems.
• Durable Construction: High-quality plated steel prevents oxidation and fatigue, ensuring the spring rate remains constant over its service life.
• Direct OEM Replacement: Matches original equipment specifications to maintain the safety listing and performance profile of the regulator.

Common Questions:

Which regulators are compatible with the R5210-25 spring?
This spring is verified for use in the Maxitrol RV52, R500, and R500S series. Always check the regulator’s data plate to confirm the model series before installation.

Can I use this spring to convert a regulator to a different pressure range?
Yes, the R5210-25 is used to set the outlet pressure between 2.0" and 5.0" W.C. If your application requires a higher or lower range, a different color-coded Maxitrol spring must be selected.

Does the spring color matter for identification?
Yes, Maxitrol springs are color-coded or plated to signify specific tension and pressure ranges. The R5210-25 is a plated spring, distinguishing it from other ranges like the 1-3.5" or 3-8" options.
