Maxitrol R5210-412 Spring

The Maxitrol R5210-412 is a high-precision violet replacement spring engineered to establish a stable 4-12" W.C. outlet pressure range in appliance gas regulators. Designed specifically for the Maxitrol RV52, R500, and R500S series, this component is critical for technicians performing pressure conversions or field adjustments on straight-thru flow design regulators. By utilizing this OEM Maxitrol spring, contractors can ensure the regulator maintains its non-lockup poppet design performance, providing accurate and sensitive regulation even at low pressure differentials across residential and commercial gas-fired equipment.

This 9/16-inch diameter spring is calibrated for consistent response in natural gas and LP applications. Its violet color-coding allows for immediate visual identification during maintenance, preventing calibration errors in complex manifold systems. Built to withstand standard ambient temperature ranges from -40°F to 205°F, the R5210-412 ensures the valve returns to its set point with high repeatability. For installers working with NPT-ported regulators, this spring provides the necessary mechanical force to achieve the desired WC (Water Column) setting for main burner and pilot load requirements.

• Precise Pressure Range: Calibrated for 4-12" W.C., enabling flexible outlet pressure settings for various appliance requirements.
• Exact Compatibility: Purpose-built for Maxitrol RV52, R500, and R500S series regulators, ensuring a perfect seat and stack height.
• Professional Identification: Violet color-coding confirms technical specifications at a glance, streamlining field service and multicomponent installs.
• Durable Construction: Made from resilient materials to maintain tension and accuracy in high-cycle industrial gas regulation environments.
• Optimized Regulation: Supports the regulator’s cone principle flow pattern, reducing frictional resistance for maximum capacity.

Can the R5210-412 spring be used for Liquid Propane (LP) conversions?
Yes, this spring is commonly used when converting RV52 or R500 series regulators to higher pressure sets. The 4-12" W.C. range is frequently utilized for LP gas applications requiring a standard 10-11" W.C. outlet pressure.

Does this spring fit the RV47 or RV48 series?
No, this specific part number is engineered for the RV52 and R500/R500S frames. Use the Maxitrol spring selection chart to identify the correct dimensions for smaller or larger regulator bodies to ensure proper water column regulation.

Is special tooling required for installation?
Installation involves removing the regulator's top cap and stack assembly. While no specialized proprietary tools are required, a calibrated manometer must be used after installation to verify the outlet pressure and ensure the system is tuned to the appliance manufacturer's specs.
