Maxitrol R5310-25 Spring

The Maxitrol R5310-25 is a precision-engineered plated spring designed specifically for field-conversion or maintenance of RV53, R600, and R600S series gas pressure regulators. This technical component is calibrated to maintain an outlet pressure range of 2-5 inches w.c. (Water Column), ensuring the stable delivery of fuel gas to critical burners. Constructed from high-grade steel with a corrosion-resistant plating, the Maxitrol regulator spring is essential for technicians performing pressure adjustments or converting appliances from higher pressure settings down to standard operating levels. Its durable design prevents fatigue and ensures consistent diaphragm loading, which is vital for preventing the nuisance lockups or erratic pilot flames often seen with aged or incorrect spring rates. Whether you are servicing a straight-thru-flow regulator or a standard poppet-style unit, verified compatibility with the R5310-25 part number is necessary for maintaining the ANSI Z21.18 certification and equipment efficiency.

• Precise Pressurization: Specifically calibrated for a 2" to 5" w.c. spring range, providing accurate control for low-pressure gas applications.
• Broad Compatibility: Engineered for seamless integration with Maxitrol RV53, R600, and R600S series bodies.
• Corrosion Resistance: Features a high-quality plated finish to withstand moisture and chemical exposure in demanding boiler rooms or outdoor enclosures.
• Reliable Performance: Maintains consistent tension over its service life, reducing the risk of pressure drift and subsequent appliance malfunction.

Can I use this spring to convert a regulator from LP to Natural Gas?
Yes, provided the target outlet pressure for your equipment falls within the 2" to 5" w.c. range. Typically, this spring is used for standard natural gas manifold pressures (often set at 3.5" w.c.). Always verify the equipment nameplate before installation.

How do I identify the correct spring for my Maxitrol regulator?
Reference the spring selection chart for your specific regulator model (e.g., RV53). The R5310-25 is easily identified by its physical dimensions and color-coded plating, signaling the 2-5" w.c. set point capability.

Does this spring fit the RV52 series?
No, the RV52 utilizes a different mechanical profile. The R5310-25 is specifically designed for the RV53 and the R600/R600S series. Using the incorrect spring can lead to over-pressurization or gas leakage.
