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. 

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

Engineered and Flow Tested for Superior Performance
Designed for quick, positive seal-off with minimum turbulence, low restriction and maximum fluid transfer, this industrial-grade ball check valve is used in a wide variety of industrial and chemical processing applications.
Heavy-Bodied PVC or CPVC Construction
Spears True Union Ball Check Valves never rust, scale or pit, providing exceptional chemical and corrosion resistance. Strong buttress-type threads on the union nuts allow higher pressure-handling capability and quick in-line installation and servicing.

• Spears computer-engineered design provides superior fluid flow with minimum turbulence. Eliminates “chatter” often encountered in ball check valves.
• Maximum Internal Pressure of 235 psi at 73°F for the most demanding applications of 1/2" - 4" valves.
• All Spears True Union Ball Check Valves are NSF Certified for potable water use.
