The check valve d90 with an EPDM seal is a robust fitting for main pool circuits with high flows. The PVC-U body withstands chlorinated and salt water and UV radiation without material degradation. The valve is suitable for DN 90 pipework in a glued design.
The AISI 302 stainless steel spring keeps the flap reliably closed when the pump stops and thus prevents the back flow of water, which can cause pump damage or disturb the hydraulics of the pool. The operating range is 16 bar at 20 °C and 10 bar at 40 °C respectively, which covers even more demanding installations.
