Valves & Actuation
![Hayward Y-Check Valve: Automatic - PVC \ FPM](/sites/default/files/styles/list/public/images/product/aff6c8b118de75a267336c9066a0/Hayward%20Y-Check.jpg?itok=Vl7ZudWT)
Hayward Y-Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment. Hayward Y-Check Valves operate without the need for any adjustments or settings. A plastic coil (not a spring) supports the disc inside the body. When the inlet flow stops, back pressure (a minimum of 2 psi is required) moves the disc with its elastomer o-ring onto a plastic seat - shutting off the flow.Â
