The 2419852 Valve Repair Kit 4500 is a genuine OEM service kit designed for Titan Elite 5500 and PowrLiner 4500/5500 airless sprayers. It contains all the wear components needed to rebuild the pump's intake and discharge valves. The kit typically includes valve seats, valve balls, springs, O‑rings, and gaskets – precision‑engineered to original specifications for reliable sealing and long service life.
Valves are critical to pump performance. They open and close with each cycle to control fluid flow. Over time, valve seats can become eroded, balls can wear or deform, and springs can lose tension, leading to internal leakage, pressure fluctuations, and reduced output. Contaminants in the fluid can also cause valves to stick or fail to seat properly. Rebuilding the valves with this genuine kit restores proper check valve function, eliminates surging, and helps the pump maintain consistent pressure.
| Restores valve sealing | Replaces worn seats, balls, and springs to prevent internal leakage |
|---|---|
| Eliminates surging | Properly sealing valves provide smooth, consistent pressure |
| Improves priming | New valves help the pump draw fluid and maintain prime |
| Prevents backflow | Stops fluid from leaking back through the pump when idle |
| Pressure surging | Spray pressure fluctuates widely during operation |
|---|---|
| Loss of prime | Pump struggles to prime or loses prime while spraying |
| Reduced output | Sprayer cannot achieve normal flow or pressure |
| Backflow / dribble | Fluid leaks back through pump when gun is closed |

When servicing the valves, it's good practice to inspect these related components, as they can affect valve performance or may be worn.
A worn diaphragm can also cause performance issues. Inspect and replace if necessary (refer to part 2419185).
A clogged filter can introduce contaminants that damage valves. Clean or replace the filter during service.
Other seals in the fluid section may also be worn. Consider a full fluid section rebuild kit if available.
