Assembly Overview
Buy Titan 840ix Prime/Spray Valve Replacement Parts
The Prime/Spray valve assembly is part of the Titan 840ix airless sprayer's fluid-routing system. During priming, the valve arrangement allows fluid to follow the bypass or return path. During spraying, it is positioned to support delivery through the spray circuit. The valve's sealing surfaces, operating handle and internal retaining components must function correctly for dependable operation.
A damaged valve seat, deteriorated gasket, worn O-ring or faulty retaining component can contribute to leakage, difficulty priming or problems changing between operating modes. The P/N 800-915 diagram identifies 12 individual replacement parts so you can locate the correct component rather than replacing unrelated sprayer assemblies.

Troubleshooting
Common Titan 840ix Prime/Spray Valve Problems
These symptoms identify components worth inspecting, but they do not establish a diagnosis. Pump valves, suction leaks and other fluid-system faults may produce similar symptoms.
| Symptom | Parts to Inspect | Suggested Check |
|---|---|---|
| Fluid leaks around valve | 700-537, 222-012, 221-012, 700-721 | Inspect seals, housing interfaces and mating surfaces after relieving pressure. |
| Difficulty changing valve position | 700-697, 700-251, 700-759 | Check handle and cam-related components for damage or obstruction. |
| Unexpected bypass flow | 800-910, 700-253, associated seals | Inspect the bypass seat and valve sealing arrangement. |
| Damaged internal retention | 700-823, 700-248, 800-926 | Inspect retaining hardware and spring condition using the assembly diagram. |
| Sprayer fails to prime | Prime/Spray valve and related intake system | Verify valve position and inspect the siphon set and pump valves before replacing parts. |
