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

PVC Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second.
• Pressure Rating - 150 psi @ 73°F   • Maximum Service Temperature - 140°F   • EPDM seal for positive sealing
• Flow velocity < 5 ft./sec.
