The Titan 805-845 Outlet Valve Kit is a genuine OEM replacement kit designed to control paint flow from the pump to the spray hose on compatible RentSpray, Impact, and Impact X airless sprayers. The outlet valve maintains pressure during spraying and prevents backflow when the gun is triggered off.
A worn or contaminated outlet valve can cause pressure loss, difficulty priming, spitting from the tip, or paint leaking back into the pump. Replacing the valve with this complete kit restores proper sealing, consistent pressure, and reliable operation.
| Pressure holding | Prevents paint from flowing back into the pump when gun is off |
|---|---|
| Flow control | Allows pressurized paint to exit to the hose when triggered |
| Priming support | Helps build initial pressure by sealing the outlet side |
| Pressure loss | Gun pressure drops significantly while spraying |
|---|---|
| Failure to hold pressure | Pressure bleeds down quickly after pump shuts off |
| Priming issues | Pump runs but will not prime or builds pressure very slowly |
| Contamination / wear | Valve ball or seat shows pitting, debris, or grooves |

When replacing the outlet valve kit, inspect these related components for wear or damage.
Often wears at the same rate as the outlet valve. Replace both for full pump restoration.
Worn packings can cause pressure loss that mimics valve failure.
If pressure readings are erratic, the gauge or sensor may also need attention.
