  Hayward Flow Control
  Spring Loaded Y-Check Valves
  GENERAL DESCRIPTION. Backflow Prevention: Hayward's Spring-Loaded Y-Check Valves give positive protection against reversal of flow in a piping system, even in the absence of back pressure. Check valves that are not spring-loaded require fluid back pressure to seal. If an application cannot produce enough back pressure, the standard check valve can't seal. Hayward Spring-Loaded Y-Check Valves do not require system generated back pressure to work. Applications: Installed downstream of a pump... (read more)

  Hayward Flow Control
  Y-Check Valves
  GENERAL DESCRIPTION. Backflow Prevention: 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. Reliable Operation: The valve operates without the need for any adjustments or settings. A plastic coil (not a spring) supports the disc inside the valve body. When the inlet flow stops, backpressure (a minimum of 2 PSI is required) moves the disc with its elastomer o-ring onto a plastic... (read more)
