2 hayward 1/2" true union ball check
Hayward plastic true check ball check valves with viton seals, NSF listed material and 150 psi at 70 degrees F., prevent reversal of flow in piping systems. They 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. Ideal for horizontal and vertical installation. Seats with minimum back pressure. Free floating ball never seats in the same postion twice. Full port 4 inch check valve for greater flow with minimum pressure loss.
ITEMS GUARANTEED 100% WORKING.
