Titan part 930-020 is a compression spring used in the pump valve assembly of compatible PowrTwin, PowrTex, PowrLiner, and PowrBeast airless sprayers. This spring provides the necessary force to keep the valve ball seated during the pump cycle, ensuring proper sealing and consistent pressure. Replacing a worn or weakened compression spring restores correct valve timing and prevents pressure loss.

The Titan 930-020 Compression Spring is a precision‑wound spring that provides the necessary closing force for the valve ball in the pump assembly. On compatible airless sprayers, this spring ensures the valve ball returns to its seat during the intake stroke, preventing backflow and maintaining system pressure.
Over time, compression springs can lose tension, weaken, or even break due to metal fatigue and repeated cycling. A weak spring can cause poor valve seating, leading to pressure loss, erratic spray, loss of prime, or complete pump failure. Replacing the spring restores proper valve dynamics and extends pump life.
| Function | Description |
|---|---|
| Valve seating force | Pushes the valve ball firmly against its seat during intake stroke |
| Backflow prevention | Ensures a tight seal, preventing paint from flowing backward |
| Pressure consistency | Maintains stable output pressure by controlling valve timing |
| Symptom | Indication |
|---|---|
| Loss of prime | Sprayer struggles to pull fluid or loses prime easily |
| Pressure drop under load | Pressure falls off when spraying, even with good ball and seat |
| Weak or broken spring | Spring feels soft, has no resistance, or is visibly broken |
| Intermittent surging | Pressure fluctuates due to inconsistent valve sealing |

Valve spring issues often involve other pump components. When replacing the compression spring, these parts are commonly inspected or replaced at the same time.
A worn or pitted ball will not seal properly, even with a new spring – inspect and replace as needed.
The seat can become grooved or eroded, preventing a tight seal – replace with the spring and ball.
Inspect the retainer for cracks or deformation that could affect spring alignment.
