Engineered as a ½-inch FPT valve, it regulates water flow into the feeder unit, thereby controlling chlorine or bromine output for consistent pool sanitation. Constructed from chemical-resistant materials suitable for chlorinated pool water, this valve ensures reliable performance and helps maintain proper water balance and sanitation levels.\u003c\/p\u003e\n\u003ch3 data-start=\"713\" data-end=\"727\"\u003eHighlights\u003c\/h3\u003e\n\u003cul data-start=\"728\" data-end=\"1720\"\u003e\n\u003cli data-start=\"728\" data-end=\"941\"\u003e\n\u003cp data-start=\"730\" data-end=\"941\"\u003e\u003cstrong data-start=\"730\" data-end=\"756\"\u003eOEM Replacement Valve:\u003c\/strong\u003e Designed specifically for Pentair Rainbow 320, 322, and related feeder models — ensures proper fit and installation with no modification needed.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"942\" data-end=\"1109\"\u003e\n\u003cp data-start=\"944\" data-end=\"1109\"\u003e\u003cstrong data-start=\"944\" data-end=\"970\"\u003e½-Inch FPT Connection:\u003c\/strong\u003e Standard female pipe thread size ensures compatibility with typical plumbing on automatic feeders.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1110\" data-end=\"1291\"\u003e\n\u003cp data-start=\"1112\" data-end=\"1291\"\u003e\u003cstrong data-start=\"1112\" data-end=\"1137\"\u003ePrecise Flow Control:\u003c\/strong\u003e Regulates water feed into the feeder unit to maintain stable chlorine\/bromine levels and optimize chemical usage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1292\" data-end=\"1492\"\u003e\n\u003cp data-start=\"1294\" data-end=\"1492\"\u003e\u003cstrong data-start=\"1294\" data-end=\"1330\"\u003eChemical-Resistant Construction:\u003c\/strong\u003e Built to withstand exposure to chlorine\/bromine and pool water conditions without degradation — for long-term durability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1493\" data-end=\"1720\"\u003e\n\u003cp data-start=\"1495\" data-end=\"1720\"\u003e\u003cstrong data-start=\"1495\" data-end=\"1529\"\u003eEssential for Feeder Function:\u003c\/strong\u003e A fully functional control valve is critical for correct feeder operation; replacing a faulty valve restores chemical feed reliability and pool hygiene.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePentair In-Line Rainbow Chemical Feeder Models: \u003c\/strong\u003e\u003cspan\u003e320, 322, 300-29X\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"8041\" data-end=\"8060\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"8061\" data-end=\"8447\"\u003eThe Pentair R172086 control valve regulates water flow into Rainbow 320 and 322 inline feeders and related 300-series offline feeders.
