Anti-contamination valve class BA, DN32, FIG.406 406E032B34

Anti-contamination valve – system protection and safe operation

This anti-contamination valve by Zetkama, with a diameter of DN32 and designation Fig. 406, is a critical component for protecting water systems against contamination and backflow. It is an indispensable solution for both residential and industrial installations where high hygiene standards and protection against potential water pollution are required. Its design ensures not only effective protection but also easy installation and operation.

This valve has been engineered for reliability and durability. It features a compact construction and a silicone seal, guaranteeing tightness and long-term performance. Thanks to its reduced pressure zone and monitoring capability, it enables continuous monitoring of the system status and rapid response to potential issues.

Construction and application

The BA-class anti-contamination valve is equipped with an internal cylindrical gas thread BSPP-G (ISO 228-1), facilitating easy connection to existing piping systems. Its primary function is to prevent backflow of water from the installation into the water supply source, which is especially critical in cases of potential contamination within the network.

• Backflow isolation: Protects potable water from contamination by backflowing fluids.
• Pressure reduction: Minimizes the risk of damage to system components caused by excessive pressure.
• Easy installation: BSPP-G internal thread allows for quick and efficient connection to pipes.
• Durability: Constructed from high-quality, corrosion-resistant, and mechanically robust materials.
• Monitoring: Built-in inspection capability enables early detection of potential faults.

This valve is suitable for a wide range of applications, including:

• Water supply systems in residential and public utility buildings
• Garden irrigation systems
• Industrial installations requiring protection against water contamination
• Central heating systems (subject to specific requirements)

Thanks to its versatility and reliability, the Zetkama anti-contamination valve is an investment in the safety and long-term performance of the entire water system.
