Backflow prevention valve class BA, DN80, FIG.405 405A080B34

Backflow prevention valve – protection for installations and clean water

The backflow prevention valve, class BA, with a nominal diameter of DN80, is a reliable solution for protecting water installations from contamination and backflow. Its reduced pressure zone design and monitoring capabilities make it a key component in systems requiring a high level of hygiene and safety. Made of gray cast iron, coated with epoxy both inside and out, it ensures durability and corrosion resistance.

Construction and application – for installers and users

This valve, designated FIG.405, is designed for horizontal mounting. Its main function is to isolate backflows, preventing the mixing of media and maintaining the purity of drinking water. The use of a silicone seal guarantees tightness and minimizes the risk of leaks. The compact design facilitates installation even in tight spaces. The length of the flanged connection is 400 mm, ensuring compatibility with existing installations.

• Backflow prevention: Prevents contaminated water from flowing back into the source of clean drinking water.
• Reduced pressure zone: Allows monitoring of the valve status and quick detection of potential problems.
• Durable construction: Cast iron body coated with epoxy provides corrosion resistance and long life.
• Easy installation: Compact design and flanged connection facilitate installation.
• Versatility: Suitable for use in various types of water installations where protection against contamination is required.
• Pressure reduction: Helps maintain optimal pressure in the system, protecting against damage to installation components.

This valve is primarily used in water installations where maintaining the purity of the medium and protecting against potential contamination are crucial. It is an ideal solution for both residential buildings and industrial or public utility facilities. Thanks to its design, it effectively prevents problems related to backflows and maintains high-quality drinking water.
