Titan part 316-924 is a ball cage, piston seat used in the fluid pump assembly of compatible Hydra airless sprayers. It houses and guides the inlet or outlet valve ball, ensuring proper seating and sealing during the pumping cycle. A worn or damaged ball cage can cause valve misalignment, pressure loss, or erratic spray. Replacing the ball cage restores correct valve operation and consistent pump performance.

The Titan 316-924 Ball Cage, Piston Seat is a critical component of the valve system inside the fluid pump. It holds the valve ball in precise alignment with the piston seat, allowing the ball to seal properly during the pressure stroke and open cleanly during the intake stroke. This part is essential for maintaining pump efficiency and consistent fluid output on Hydra M‑series and Hydra Pro Super sprayers.
Over time, the ball cage can wear, become deformed, or develop cracks, leading to improper ball seating. Symptoms include loss of pressure, erratic spray, difficulty priming, or fluid bypass. Replacing a worn or damaged ball cage with this genuine Titan part restores correct valve geometry and reliable pump performance.
| Ball alignment | Keeps the valve ball centered over the seat for proper sealing |
|---|---|
| Controlled movement | Guides the ball during opening and closing to prevent side‑loading |
| Flow efficiency | Reduces turbulence and allows smooth fluid passage through the valve |
| Pressure loss | Sprayer cannot maintain pressure; fluid bypasses the valve |
|---|---|
| Erratic spray | Intermittent or pulsing output due to inconsistent valve sealing |
| Visible damage | Cracks, deformation, or excessive wear on the cage |
| Valve rebuild | Replace the cage as part of a complete valve service to ensure reliability |

When servicing the piston seat valve, it is standard practice to renew these associated components to ensure a complete repair.
The ball mates with the seat; if it is worn or out of round, the valve will not seal properly.
The seat surface should be smooth and free of nicks; replace if damaged.
If applicable, replace the spring that helps return the ball to the seat.
