Check Valves

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. 

Features
• 150 psi @ 70°F (non-shock)     • Full flow design, works in any position

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.

PVC Utility Spring-Assisted 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. Excellent for Pool and Spa, OEM and General Purpose applications.

• Pressure Rating - 150 psi @ 73°F     • Maximum Service Temperature - 140°F (Temperature/Pressure De-Ratings Apply)
• EPDM seal for positive sealing      • Stainless steel spring assisted (non-adjustable)
• Minimum opening pressure is 0.5 psi.
