Graco 15F610 Check Valve 2Qt Cup

Product Overview

The Graco 15F610 Check Valve 2Qt Cup is a genuine OEM check‑valve designed to work with Graco 2‑quart cup assemblies. It ensures one‑way fluid flow from the cup to the sprayer mechanism, preventing backflow and maintaining consistent, reliable fluid delivery during spray operations. This check valve helps preserve system integrity and paint or coating quality by preventing fluid from running backward into the cup under pressure or when the sprayer is idle. Built to Graco’s standards, 15F610 supports stable, leak‑free operation under typical cup‑pot pressures and delivers long service life when used and maintained correctly.

Installation / Usage Instructions

To install or replace the 15F610 Check Valve properly, follow these steps:

• Ensure the sprayer is turned off and depressurized before working on the fluid cup assembly.
• Remove the existing valve (if present) and clean the mating threads or sealing surfaces to remove dried coating or residue.
• Install the new 15F610 check valve, ensuring correct orientation (check‑valve arrow/direction must allow flow from cup toward sprayer).
• After installation, test the system: fill the cup, pressurize (if applicable), and check for proper flow and absence of backflow or leaks before spraying.
