Titan part 241-109 is a pin ball stop designed for use in the fluid section or valve assemblies of compatible Admiral, Commander, and Hydra sprayers. This pin limits the travel of the valve ball, ensuring proper seating and consistent one‑way flow. Replacing a worn, bent, or missing pin ball stop restores accurate valve operation, prevents material bypass, and maintains system pressure.

The Titan 241-109 Pin Ball Stop is a genuine OEM component that controls the travel of the valve ball in the fluid section or valve body of compatible Admiral, Commander, and Hydra sprayers. It acts as a mechanical stop, ensuring the ball seats properly against the valve seat during the pump’s pressure stroke while allowing sufficient movement for material flow.
Over time, the pin ball stop can become bent, worn, or lost due to debris, improper assembly, or normal cycling. A damaged or missing pin allows the valve ball to travel too far, leading to poor seating, material bypass, pressure loss, and erratic spray patterns. Replacing with the correct 241‑109 pin restores proper ball travel, ensures reliable valve sealing, and maintains consistent pump performance.
| Limits ball travel | Prevents the valve ball from moving beyond the seat |
|---|---|
| Ensures proper seating | Allows the ball to return to the closed position reliably |
| Maintains flow direction | Supports one‑way flow by controlling ball position |
| Bent / deformed | Pin no longer provides correct stop position |
|---|---|
| Worn / grooved | Surface wear from ball contact |
| Missing | Pin lost during previous service |
| Material bypass | Valve fails to close, indicating ball travel issue |

When replacing the pin ball stop, inspect these related components for wear or damage.
Inspect the ball for scoring or out‑of‑round condition; replace if damaged.
Check the seat for pitting or wear; replace as a set with the ball.
If the valve uses a spring, verify it is not fatigued or broken.
