Backflow preventer, flanged DN 80 BA300-80A

Protection of installations and drinking water – backflow preventer DN 80

This flanged backflow preventer, with a nominal diameter of DN 80, is a key element protecting the water installation from unwanted backflow. Its use minimizes the risk of drinking water contamination and damage resulting from back pressure or flooding. It is a reliable solution for both installers and end-users, providing long-term system protection.

Design and application

The BA300 isolator is designed to protect drinking water systems from contamination caused by back-siphonage or backflow under pressure. It meets the requirements of PN-EN 1717 standard and is classified as category 4 according to this standard, which means it provides protection for liquids up to this category. The body made of ductile iron with a powder coating guarantees high corrosion resistance and durability. This makes the isolator perfect for residential, commercial, industrial and public utility buildings. Installation should be horizontal with the lower drain valve.
