Noken 100117768 Diverter Cartridge Assembly for NK Porcelanosa Valves

This diverter cartridge sits inside the NK Porcelanosa shower valve and manages the changeover of water between outlets such as an overhead spray, a handset or a bath spout. When the diverter is working properly, the valve should send water cleanly to one outlet at a time without any crossover or pressure loss.

Function

Inside the valve body, the cartridge redirects the internal flow path as the user turns the selector. Over time the moving components or the O-rings can wear, which often shows up as water feeding two outlets at once, a diverter that feels tight or loose, or an outlet that does not fully engage. Replacing the diverter assembly typically resolves these issues and restores a firm, positive switching action.

Confirmed Compatibility

This cartridge assembly is used in NK Porcelanosa shower valves that specifically list part code 100117768 in their technical documentation. It should only be installed when the original diverter or the valve’s parts diagram confirms this exact code, as Porcelanosa use several diverter formats across different valve families.

Installation Notes

The diverter is accessed from the front of the valve once the trim and handle have been removed. Alignment matters on reassembly, and it is worth checking that the locating tabs and seals are seated correctly before tightening the retaining components. A quick movement test of the selector before refitting the faceplate helps ensure the diverter is engaging properly.

When Replacement Is Recommended

A new diverter is usually required when switching between outlets becomes inconsistent, when water escapes from a second outlet, or when the selector mechanism feels uneven through its travel. Installing a fresh 100117768 assembly restores smooth outlet control and helps maintain the intended performance of the Porcelanosa valve.
