When the original valve wears or no longer holds a consistent setting, replacing it with the correct OEM part restores accurate chemical dosing. Match the part number on your existing valve before ordering — this is the old-style version, and a revised design may have superseded it on later feeder configurations.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eR172022\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eOld Style Chlorine Control Valve\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eCompatible Feeder Models\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e300, 302, 300-19, 300-29\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\n\u003cp\u003eBefore ordering, confirm this is the \"old style\" valve by comparing the part number stamped or molded on your existing component. Pentair updated the design on some Rainbow feeder models — if your feeder is a later production unit, a revised valve part number may apply. Check your feeder's parts diagram or the number on the original valve to confirm R172022 is the correct fit for your specific unit.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53971990708499,"sku":"R172022","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-old-style-chlorine-control-valve-rainbow-chemical-feeder-models-300-302-300-19-300-29-r17202.webp?v=1779200908","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_r172022","provider":"Poolaroo","version":"1.0","type":"link"}
