The 451-085 Cage Ball is an OEM internal check-valve part used in the pump fluid section of multiple Titan PowrTex, PowrTwin, and PowrLiner airless sprayers. It works with the valve cage and seat to regulate one-way fluid movement through the pump.
Proper cage ball operation is essential for maintaining prime, preventing pressure drop, and ensuring consistent pump cycling. A worn or damaged cage ball can cause surging, poor prime retention, or reduced spray performance.
| Check valve action | Allows fluid to flow in one direction while preventing backflow |
|---|---|
| Prime retention | Helps the pump maintain prime between cycles |
| Pressure stability | Supports consistent pressure output during spraying |
| Loss of prime | Pump fails to hold prime after shutdown |
|---|---|
| Surging | Pressure fluctuations during spraying |
| Wear or pitting | Visible damage to the ball surface |
| Routine rebuild | Part replaced during scheduled pump service |
