Flap check valve 1 1/2" F-F

The swing check valve is a reliable component for water installations, designed to prevent backflow and protect the system against contamination. With a 1 1/2" nut-to-nut connection, it fits standard domestic and light commercial pipework and supports stable operation in cold and hot water systems.

The durable CW617N brass body resists corrosion in long-term contact with water, while the brass closing element and NBR sealing ring maintain tight shut-off under a nominal pressure of up to 16 bar. The internal flow path is engineered for efficient water passage, so the valve supports consistent performance in demanding installations.

Nickel-free wetted surfaces suit applications where contact with drinking water is expected and help reduce the risk of nickel release into the medium. Compact external dimensions of approximately 90 x 55 x 80 mm make the valve easy to position in confined spaces, and the G1 1/2 connection thread integrates smoothly with typical plumbing fittings.

This brass check valve is a solid alternative to a standard backflow preventer in water systems, offering robust construction, safe materials, and convenient installation for anyone looking to build a dependable plumbing installation.
