Backflow prevention valve 3/4 inch class EA ZZA02W

Backflow preventer – installation protection and user safety

A 3/4 inch, EA class backflow preventer is a reliable protection for the water installation against backflow. Its construction and materials guarantee long-lasting and trouble-free operation, and the precision of execution translates into effective protection against contamination. It is a key element in systems where protection of drinking or process water is required against potential contamination.

Construction and application

The valve is designed for installation in water systems where there is a risk of medium backflow. EA class means that the valve meets the requirements of standards regarding protection against contamination by backflow in category 2 (pressure). It can be used both in residential and industrial buildings, as well as in irrigation systems. Thanks to the possibility of installation in any working position, it provides flexibility during installation.

• Pressure resistance: the nominal working pressure is 1.0 MPa (10 bar), which ensures safe operation under typical conditions.
• Thermal resistance: the valve is adapted to work at a temperature of up to 65°C, and a short-term temperature increase to 90°C does not affect its functionality.
• Versatility: the possibility of installation in any position facilitates adaptation to specific installation conditions.
• High-quality materials: the materials used ensure corrosion resistance and long device life.

This valve is an important element ensuring the installation complies with applicable standards and regulations regarding the protection of drinking water. Its installation is an investment in safety and hygiene of water use.
