Graco 15A207 Ball Support – High‑Precision Valve Positioner
The Graco 15A207 Ball Support is a critical OEM component designed to accurately guide and stabilize the valve ball in Graco regulator systems. Its precision-machined design ensures the ball remains centered under dynamic conditions, promoting consistent sealing and long-term reliability.
Product Overview
This ball support is engineered to provide a robust foundation for the valve ball, minimizing lateral play and improving return alignment. By reducing vibration and maintaining optimal geometry between the ball and valve seat, the 15A207 helps sustain effective flow control, tight sealing, and stable pressure regulation even in high-cycle applications.

Installation Guidelines
- Depressurize and drain the system before working on the valve.
- Disassemble to access the valve ball, seat, and existing support.
- Remove the old ball support and clean all mating surfaces.
- Inspect the ball and seat for wear or damage before installing the new support.
- Install the 15A207 ball support, ensuring it is seated correctly and centered.
- Reassemble the valve, replace any worn seals, and torque fittings to specification.
- Repressurize the system gradually and verify correct operation and sealing.
Maintenance Advice
- Check the ball support periodically during regulator maintenance.
- Inspect for signs of wear, scoring, or misalignment.
- If the support shows damage or deformation, replace it with the OEM 15A207.
- Clean and lubricate all internal components as you reassemble to ensure smooth operation.
Frequently Asked Questions
It secures the valve ball in position, maintaining ideal alignment and reducing lateral movement, which improves sealing and regulator stability.
Yes — the 15A207 is a factory-specified Graco component, designed for use in compatible regulator assemblies.
Replace it if you detect leaking, poor valve seating, or visible wear on the support face, as these could adversely affect performance.
After installation, repressurize slowly, check that the valve ball returns cleanly to its seat, and verify there are no leaks or misalignment.
