Series 9661

The 9661 backflow preventer has been specially designed for connection to a ½-inch tap and offers a flexible solution for mobile and decentralised applications.

It reliably protects drinking water systems in accordance with DIN EN 1717 up to fluid category 4 against backflow, backpressure and back-sucking.

Typical applications include heating system top-ups, high-pressure cleaners and irrigation systems.

Thanks to its lead-free material, low pressure drop and compact design, the 9661 is ideal for flexible use whilst ensuring high levels of operational safety.
