Part 50164 is a replacement outlet valve ball for a wide range of compatible spray equipment. This precision ball serves as the check mechanism in outlet valves, allowing one-way flow of material. When the original ball becomes worn, pitted, or damaged, replacement restores proper valve sealing and pump performance.

The 50164 outlet valve ball is a direct replacement check valve component for a wide range of spray equipment including Advantage 400/500, Helix LP, multiple Impact models (340, 400, 410, 440 service, 640 I and IA, 640, X 410, X 440, X 540i), PowrLiner 1800M/2800M, RentSpray 400/500/600 Impact, and numerous SprayTech models (Airless Advantage EPX2155/EPX2255, Airless EP2105/EP2205/EP2300 SE/EP2300/EP2400/EPX2155/EPX2255, GPX 80, GPX 750, LCX 750). This precision-ground ball is used in outlet valve assemblies, where it seats against a valve seat to prevent backflow during the intake stroke and lifts during the pressure 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. It is made from a wear-resistant material compatible with paints and solvents. Installation requires careful handling to avoid damage and proper seating against the valve seat. Regular inspection during pump service helps identify balls that need replacement.
| Check valve action | Allows one-way flow of material |
|---|---|
| Sealing | Seats against valve seat to prevent backflow |
| Pressure maintenance | Helps maintain system pressure |
| Worn / pitted surface | Ball no longer seals against seat |
|---|---|
| Out-of-round | Ball deformed, cannot seal properly |
| Loss of pressure | Pressure drops due to valve leakage |
| Backflow | Material flows backward through valve |
