TC Series True Union Ball Check Valves
Prevent reversal of flow in piping systems with Hayward® true union ball check valves. Valves have FPM seals, NSF-listed material and withstand up to 150 psi at 70°F. 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 backflow.
Safe for horizontal or vertical installation. Seats with minimum back pressure. Free floating ball never seats in the same position twice. Full port 4" check valve for greater flow with minimum pressure loss. Min 2 psi cracking pressure on all sizes. 2–4" valves have PVC EPDM socket ends.
