Fleck 3150 Filter | Chrono NXT2 NBP - no tank adapter - No DLFC V315NC-601

3150 Filter: Engineered as a dedicated 3-cycle or 5-cycle media filter valve (backwash, rinse, service) rather than a brine-drawing softener configuration. Chrono NXT2: Equipped with Pentair’s high-contrast digital OLED touch-controller, capable of networking up to 8 valves together.NBP (No Bypass Piston): Houses a specialized internal piston that completely cuts off the outlet water flow to the factory or facility during backwash. This prevents raw, unfiltered water from leaking downstream into the service lines while the media is being cleaned.No Tank Adapter: Shipped as the raw valve body only. It does not include a top or side-mount tank flange adapter, which must be purchased separately depending on your pressure vessel configuration. No DLFC: Does not include a pre-installed Drain Line Flow Control button or assembly, allowing you to manually scale the backwash waste line flow rate to match your specific filtration media density.
