| Material flows from bleed hose when valve is closed |
944-024 knob travel, 944-026 stop, 761-715 ball, 944-904 seat, contamination, and housing alignment |
Confirm full closure, then inspect and clean the ball and seat together before replacement. |
| Valve is difficult to turn |
944-024 knob, stem, 944-026 stop, 944-004 O-ring, dried coating, housing threads, and overtightening |
Relieve pressure and isolate binding before replacing the knob, stop, or seal. |
| External leak around valve housing |
944-020 housing, 944-004 PTFE O-ring, 945-003 gasket, seat threads, cracks, corrosion, and filter-port connection |
Locate the exact interface and inspect mating surfaces before replacing the seal, gasket, housing, or seat. |
| No flow through bleed hose during priming |
knob opening travel, valve stop, ball release, seat passage, housing passage, bleed hose, return fitting, and coating blockage |
Clear the hose and passages and verify ball movement before replacing valve components. |
| Pump cycles slowly with gun closed |
partially open bleed valve, worn ball and seat, lower pump packings, loose fluid connections, and check balls |
Confirm whether coating exits the bleed hose before diagnosing the pump or replacing valve parts. |
| Pressure does not relieve predictably |
valve opening, bleed-hose restriction, knob and stop movement, seat passage, gun trigger, and trapped hose pressure |
Stop operation and verify the full Titan pressure-relief sequence before servicing the valve. |
