Check Valves
Backflow Prevention
Hayward True Union Ball Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment.
True Union Design
Sizes 1/2” to 4” feature a true union design. This allows for easy removal from a piping system without breaking down piping connections. Pressure rating of 150 psi @ 73°F (non-shock).
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.
