About This Item

The Pentair 271163Z is the OEM replacement valve diffuser for the HiFlow 1-1/2" and 2" Top Mount and Side Mount Multiport Valves, including models 261124, 261055, and 261152.

The valve diffuser is an internal component of the multiport valve assembly. It directs water flow through the valve's internal ports, ensuring proper distribution across each valve position. A damaged or worn diffuser can result in reduced flow performance, port bypass, or incorrect valve function.
