The check valve of 25 mm diameter made of PVC-U is fitted with an AISI 302 stainless steel spring and an EPDM rubber seal, which resists both chlorinated and brominated water in pool circuits.
The maximum operating pressure of 16 bar at 20 °C and 10 bar at 40 °C corresponds to the standard operation of domestic and semi-professional pool systems. The valve prevents backflow even when the pump fails, thereby preventing surges in the pipework.
The Portuguese manufacturer guarantees precise dimensions and high build quality, thanks to which the valve operates correctly even at low pressure differentials, where cheaper alternatives fail.
