Backflow preventer, flanged DN 100 BA300-100A

Protection of installations and drinking water – backflow preventer BA300-100A

This backflow preventer, designed for flanged mounting with a DN 100 diameter, is a key element in protecting the water installation from contamination and backflow. The device protects against back-siphonage and backflow under pressure, which is particularly important in drinking water systems. It meets the requirements of EN 1717 standard, providing protection for liquids up to category 4.

The BA300-100A isolator is used in both residential buildings, as well as commercial and industrial facilities. Its solid construction made of ductile iron with a powder coating guarantees durability and corrosion resistance. This makes the device suitable for demanding operating conditions, minimizing the risk of failure and ensuring long-term protection of the installation.

• Versatile application: ideal for protecting drinking water installations in residential, commercial and industrial buildings.
• Protection compliant with standards: meets the requirements of EN 1717 standard, providing protection for liquids up to category 4.
• Durable construction: the body made of ductile iron with a powder coating provides corrosion resistance and long-term operation.
• Easy servicing: the design allows easy access to internal components, facilitating maintenance and repairs.
• High efficiency: the nominal flow rate is 108 m³/h with a pressure drop of 1 bar.
• Safety confirmed: has a PZH Hygienic Certificate and meets the requirements of KTW for drinking water.

The design of the isolator is based on the principle of double protection – two check valves and a relief valve, which divide the device into three independent zones. This solution provides maximum protection against contamination of the installation. The device is also characterized by its low weight (58 kg) and standardized drain connection, which facilitates installation and maintenance. Remember to mount it in a horizontal position with the lower drain valve for proper operation. The manufacturer's warranty – 5 years from the date of production – further confirms the high quality and reliability of the product.
