- Spears® Y-Check valves are an angle type check valve that automatically stops reverse flow by the dead weight of the disc plug. Y-checks are less affected by turbulent flow and typically have lower shutoff characteristics than ball checks. Valves are available in PVC gray, PVC clear, and CPVC materials in IPS sizes 1/2 in through 4 in with socket, SR threaded or flanged end connections, plus True Union styles with socket and SR threaded ends.
