Graco 15A206 Ball Support – Enhanced Valve Stability Component
The Graco 15A206 Ball Support is a high‑precision OEM part designed to stabilize and center the valve ball within Graco regulator and fluid handling assemblies. This component helps ensure consistent valve sealing, reduces oscillation during operation, and contributes to reliable regulatory performance.
Product Overview
This ball support component is engineered to hold the valve ball in perfect alignment, even under repeated cycles of pressure and flow changes. By maintaining the correct position of the ball, the 15A206 reduces wear, mitigates vibration, and preserves the longevity of critical valve internals. Its design ensures the ball returns precisely to its seat, helping maintain consistent regulator set points and optimal sealing performance.

Installation Guidelines
- Depressurize and drain the system before disassembling the valve.
- Remove the existing valve ball, seat, and support components.
- Inspect the ball, seat, and bore for wear or damage.
- Clean all mating surfaces to remove debris or residue.
- Install the new 15A206 Ball Support, ensuring it sits evenly in its bore.
- Reinstall the ball, spring, and other internal parts, then reassemble the regulator.
- Repressurize slowly and test the valve operation for correct seating and performance.
Maintenance Advice
- Inspect the ball support during routine maintenance or when valve leaks are detected.
- Check for signs of deformation, scoring, or misalignment.
- Replace the 15A206 support if wear compromises the ball’s return or seating.
- Clean and lubricate all components following manufacturer recommendations during reassembly.
Frequently Asked Questions
It provides firm alignment and support for the valve ball, ensuring precise seating, reduced vibration, and better sealing consistency.
Yes, the 15A206 Ball Support is a factory-specified Graco part engineered to OEM tolerances for reliable performance.
Replace it if you notice valve leakages, inconsistent seating, or wear on the support face — these can impact performance and sealing.
After assembly, slowly repressurize the regulator and observe the valve ball’s operation — it should seat cleanly with no wobble or leakage.
