The BA Mini 6625 is a compact check valve designed to protect against contamination of drinking water by backflow. Its purpose is to prevent back siphonage or backflow of non-potable water into the public drinking water system. The valve covers a wide range of application possibilities, including use in printing, chemical and food industries, laboratories, and medical technology. It is designed as a system with three pressure zones with controllable pressure zones before and after the valve, with an intermediate pressure zone in between. It also includes two isolation valves and is equipped with three ball valves for functionality testing by pressure measurement.

Features:

• Maximum operating pressure: 10 bar
• Maximum operating temperature: 65°C
• Connection size to the system: DN 20
• Installation: horizontal position with the drain valve facing downwards
• Material: body made of high-quality low-lead brass alloy and high-quality synthetic material, internal parts made of corrosion-resistant materials or stainless steel
• Recommendation: installation of a drinking water filter before the valve, thorough flushing of the piping before installation

All synthetic parts that come into contact with drinking water intended for human consumption are approved by the German Public Health Authority (KTW). Regular maintenance is important to maintain proper functionality, and a service agreement between the user and the installer is recommended. The valve is designed with a cartridge system for easy and trouble-free maintenance.
