Prevent Backflow With Durable Check Valves

Browse check valves at Stockpile Express and find options for residential, commercial, and industrial applications. A check valve ensures the water, oil, or gas in a pipe system flows in one direction, avoiding backflow and contamination. We offer y-pattern, hydronic flow, in-line, and swing-style check valves to accommodate different needs. Whether you're looking for a check valve for your gas-powered boiler or your hydronic heating system, explore our selection and find durable, corrosion-resistant options from Apollo, Red White, and Watts.
