The set includes the sealing discs that open and close the valve's internal ports as the control head rotates through its regeneration sequence, making it one of the most important wear items in any Autotrol rebuild.\u003c\/p\u003e\u003ch3\u003eWhy disc sets matter\u003c\/h3\u003e\u003cp\u003eInside an Autotrol control valve, the discs seal against ports to direct water through the service, backwash, brine, and rinse positions. They are in constant contact with moving surfaces and water flow, so over time they harden, scratch, take a set, or wear unevenly. When that happens, you may see internal leaks, weak or incomplete regeneration, hard water slipping past during service, or water running continuously to the drain. Because the discs work as a matched group, replacing the full set at once ensures even, consistent sealing rather than pairing a fresh disc with worn neighbors.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine Pentair Autotrol valve disc set\u003c\/li\u003e\n\u003cli\u003eFits Autotrol valve models 163 and 168\u003c\/li\u003e\n\u003cli\u003eReference number 155a152\u003c\/li\u003e\n\u003cli\u003eRestores proper port sealing and cycle control\u003c\/li\u003e\n\u003cli\u003eItem weight: 0.19 lbs\u003c\/li\u003e\n\u003cli\u003eIdeal for valve rebuild and maintenance kits\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIf your softener has gradually lost capacity, fails to regenerate cleanly, or shows signs of internal bypass, a fresh disc set is one of the most effective and economical fixes available. This is a part that professional water treatment technicians routinely replace during scheduled overhauls, often alongside seals and springs, to return an aging valve to like-new sealing performance.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm your valve is a 163 or 168 model so the disc geometry matches your control body exactly. It also helps to inspect the sealing surfaces and o-rings while the valve is apart, since addressing related wear in the same service visit prevents repeat teardowns. With a new disc set installed, your Autotrol valve returns to crisp, dependable cycling and efficient soft-water delivery. Replacing the discs as part of a planned overhaul, rather than waiting for a hard-water complaint, lets you schedule the work on your terms and keeps the household supply consistently soft between service intervals.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668755767349,"sku":"AT1033013","price":93.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/at1033013.jpg?v=1782532366","url":"https:\/\/watersoftenerplus.com\/pl-eu\/products\/autotrol-valve-disc-set-163-168155a152","provider":"Water Softener Plus","version":"1.0","type":"link"}
