The Pentair/Rainbow AF 320 Check Valve w/Restrictor is a check valve component from Pentair/Rainbow designed to help control one-way water flow. It is intended for pool, spa, bath, cleaner, heater, pump, plumbing, or equipment repair situations where matching the correct replacement part matters. Reduce unwanted backflow through the plumbing line, especially when the existing component is worn, damaged, leaking, brittle, corroded, or no longer operating as expected. Match the part number and model reference to your existing equipment before ordering.
Valve components are often application-specific, so connection size, body style, port count, flow direction, and material should be reviewed before installation. Replacing a worn or damaged valve part helps improve water routing, chemical feed performance, equipment isolation, and general plumbing reliability. Because many pool and spa parts look similar across model generations, compare this item against the original component, equipment label, manual, and connection style before completing the repair. This helps ensure the replacement supports the intended function and fits the surrounding assembly properly.
