{"product_id":"pentair-2-black-top-valve-cover","title":"Pentair 2\" Black Top Valve Cover","description":"\u003cp data-path-to-node=\"0\"\u003eThe Pentair 2\" Black Top Valve Cover (part number 271169 or 14971-SM20E6 depending on the exact valve variant) is a critical structural sealing and control component engineered exclusively for high-volume Pentair and Sta-Rite 2-inch multiport backwash valves. It is standard hardware on 2-inch top-mount and side-mount configurations serving large-scale filtration lines, such as the Pentair FNS Plus, Tagelus, and Triton II sand or Diatomaceous Earth (D.E.) systems.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eInjection-molded from thick-walled, high-impact, and glass-reinforced ABS thermoplastic polymer, this circular lid functions as the primary pressure-retaining cap for the entire upper valve body. Its primary operational role is to enclose the internal spring, diverter, and key stem mechanism while anchoring the directional control handle. When secured across the main valve body with its structural stainless steel bolts, it creates an absolute watertight and airtight compression boundary. This heavy-duty interface allows the multiport assembly to safely direct high-velocity water movement during filter, backwash, rinse, waste, closed, and recirculate modes, safely sustaining continuous internal operating pressures up to 50 PSI without weeping, flexing, or thread deformation under extreme pump vibration surges.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eEngineered to survive decades of punishing outdoor weathering, shifting thermal stress, and direct UV exposure on the equipment pad, its robust composite architecture completely resists material degradation, stress-cracking, and chemical bleaching from direct contact with highly concentrated pool sanitizers like chlorine, bromine, and winterizing acid washes. Due to its rigid, thick-rimmed circular plastic profile designed to house 2-inch internal fluid pathways, this individual replacement valve cover carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"2\" data-index-in-node=\"567\"\u003e1.10 to 1.25 pounds\u003c\/b\u003e (about 17.6 to 20.0 ounces).\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416208728175,"sku":"271169","price":210.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/PentiarPacFab2-Por_40b44044-f8df-4233-8ca6-52a04bef85fd.jpg?v=1782745283","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-2-black-top-valve-cover","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
