About the Part
The Graco 239267 Pressure Drain Valve Kit (often called the prime/spray valve) replaces the complete valve body and internal mechanism that controls line pressurization and safe pressure relief/draining. A fresh valve helps cure hard-to-prime issues, leak-back while spraying, or failure to depressurize.

Frequently Asked Questions
Many Ultra Max II models use this pressure/drain valve style. Confirm by checking your unit’s parts list for 239267 (or an explicitly cross-referenced supersession) and verifying the manifold thread and mounting pattern.
Difficulty priming, pressure loss while spraying, constant bypass to the drain hose, or inability to relieve pressure when switching to drain mode are common indicators.
Yes—this listing is for a Genuine Graco replacement kit. Using OEM parts helps maintain performance and compatibility.
Follow Graco guidance for your manifold thread type. Typically, apply approved thread sealant on NPT threads; avoid contaminating internal passages. Do not over-torque.
Some sprayers use alternate valve bodies. If your parts manual lists a different number, order that exact part or its official supersession. Contact support with your model & series for a precise match.
