Hayward® Polypropylene True Union Ball Check Valves

These check valves are ideal where backflow could potentially cause damage to pumps, filters, or process equipment. Line pressure unseats the solid plastic ball to open the valve. When inlet flow ceases, the back pressure seats the ball on a special square cut elastomer seat, thus stopping the back flow.

  • Polypropylene
  • FPM O-ring
  • Square cut seat for positive sealing
  • Full port
  • For horizontal or vertical installation
  • Seats with minimum back pressure
  • Free floating ball never seats in the same position twice
  • Pressure rating: 150 psi @ 70°F non-shock
  • Maximum temperature: 200°F
  • NSF 61 certified
