Air-Aqua check valve 32 mm
These virtually resistance-free non-return valves prevent the water from running back. The pump experiences very little back pressure and the pump losses are therefore negligible. The non-return valve is supplied with a coupling on both sides. This makes them easy to disassemble and you do not need an additional 3-piece coupling.
A 1” connection is supplied. With the supplied socks a connection of 32 mm can be made. Please note, this lengthens the non-return valve.
