Part 762-145 is a replacement inlet valve ball for a wide range of compatible spray equipment. This precision ball serves as the check mechanism in inlet valves, allowing one-way flow of material into the pump. When the original ball becomes worn, pitted, or damaged, replacement restores proper valve sealing and pump performance.

The 762-145 inlet valve ball is a direct replacement check valve component for an extensive range of spray equipment including numerous RentSpray models (Plus, 650, 600, 600 Impact, 500, 450), ProMark II, PowrLiner models (3100, 2800, 1800M/2800M), Performer 640 i Airless Sprayer, multiple Impact models (X 540i, X 440, X 410, 640, 640 I and IA, 440 service, 410, 400, 340), Helix LP, Epic models (690 HPG, 660HPX, 447HPX), Elite G40/E15, Advantage 500/400, and various Airless Sprayer models (1100 XC, 690 GXC, 660 XC, 640 IX, 640 i, 550 XC, 540 IX, 440i, 440 XC, 440 IX, 440 i, 340, 330). This part may also be ordered as Titan 509583. This precision-ground ball is used in inlet valve assemblies, where it seats against a valve seat to prevent backflow during the pressure stroke and lifts during the intake stroke to allow material flow. A smooth, perfectly round ball is essential for achieving a positive seal and reliable valve operation. A worn, pitted, or out-of-round ball can cause leakage, pressure loss, and reduced pump efficiency. This replacement ball is manufactured to exact specifications for diameter, roundness, and surface finish.
| Check valve action | Allows one-way flow into pump |
|---|---|
| Sealing | Seats against valve seat to prevent backflow |
| Prime maintenance | Helps keep pump primed |
| Worn / pitted surface | Ball no longer seals against seat |
|---|---|
| Out-of-round | Ball deformed, cannot seal properly |
| Loss of prime | Pump loses prime frequently |
| Backflow | Material flows backward through valve |
