Part 13380 is a replacement lower ball stop disc for compatible SprayTech airless sprayers. This disc limits the travel of the check ball in the lower valve assembly, ensuring proper valve timing and preventing ball migration. When the original disc becomes worn, deformed, or damaged, replacement restores proper valve function.

The 13380 lower ball stop disc is a direct replacement component for SprayTech Airless EP2300 SE, EP2300, and EP2400 sprayers. This precision disc is installed in the lower valve assembly of the pump, where it serves as a stop for the check ball. During pump operation, the check ball lifts off its seat to allow material to enter the pump chamber on the intake stroke, then returns to the seat to prevent backflow during the pressure stroke. The ball stop disc limits the upward travel of the ball, ensuring it lifts just enough for proper flow without excessive movement that could cause delayed seating or damage. A worn, deformed, or damaged disc can alter ball travel, leading to incomplete sealing, reduced pump efficiency, and erratic pressure. This replacement disc is manufactured to exact thickness and diameter specifications for proper fit and function. Installation requires access to the valve assembly and careful cleaning of all components. Regular inspection during pump service helps identify disc wear before it affects performance.
| Ball travel limit | Controls how far check ball lifts from seat |
|---|---|
| Valve timing | Ensures proper opening and closing timing |
| Flow regulation | Affects material flow into pump |
| Worn disc | Thickness reduced, allowing excess ball travel |
|---|---|
| Deformed shape | Disc no longer flat, affects ball seating |
| Loss of prime | Pump loses prime due to valve issues |
| Erratic pressure | Pressure fluctuations from improper valving |
