Part 941-555 is a replacement ball valve for a wide range of compatible spray equipment. This valve controls fluid flow by rotating a ball with a bore, providing reliable on/off control. When the original valve becomes worn, leaks, or fails to operate smoothly, replacement restores proper flow control.

The 941-555 ball valve is a direct replacement flow control component for an extensive range of spray equipment including numerous PowrTwin models (TM 8900 XLT, 12000GHD, 12000GH, 12000 XLT, 12000 XLT DI, 12000 Plus DI service, 12000 Plus DI Operation, 12000 GHD, 8900GH, 6900GH, 6900 XLT, 6900 XLT DI, 6900/12000 Plus DI, 4900GH, 4900 XLT, 4900/6900/8900/12000 Plus, 4500, 3500 50th anniversary), PowrTex 6900SF/12000SV (including 0528919D), various PowrLiner models (8900, 8900 XLT, 8900 XLT SP, 6950_1, 6950, 6900 XLT, 6900 XLT SP, 6000, 5000, 4950, 4900, 4900 XLT, 4000, 4955/6955/8955), Hydra M and Hydra Pro 2000_4000, Hydr M nad Hydra Pro Super, Commander, and Admiral equipment. This valve uses a ball with a bore through its center to control fluid flow. When the handle is turned 90 degrees, the bore aligns with the flow path to allow flow, or blocks it to shut off flow. Ball valves provide reliable, quick shut-off with minimal pressure drop. A worn or leaking valve can cause loss of control, pressure drops, and system inefficiency. This replacement valve is manufactured to exact specifications for port size, pressure rating, and material compatibility. Installation requires proper alignment and thread sealing.
