Brand: K-Rain SKU: P8003051
Product Overview
The K-Rain P8003051 is a Lite stem-and-disc replacement assembly for compatible K-Rain 6000 Series indexing valves. It combines the valve stem and disc with the 0.028-inch spring identified by K-Rain as the Lite, or white-spring, configuration.
The stem-and-disc assembly is the primary moving component that advances the indexing valve from one outlet to the next as the water supply cycles off and on. Spring selection affects the flow conditions required for dependable indexing, so the P8003051 should replace a matching Lite assembly or be selected according to K-Rain's valve-sizing and flow guidance. It should not be substituted automatically for the standard 0.032-inch or extra-lite 0.025-inch versions.
