Backflow prevention check valve, EA class, 3/4 inch, female-male thread. RV277-3/4A

The EA class anti-pollution check valve, 3/4", with internal and external threads, is a product that will certainly appeal to any user looking for not only a functional solution but also an aesthetically pleasing element for their plumbing system. The use of brass as the body material guarantees durability and resistance to mechanical damage and corrosion.

This valve has a parallel external gas thread (BSPP) connection, which allows for easy and quick installation to pipes with similar connection types. This saves time during installation and avoids additional costs associated with using specialized tools.

However, the greatest advantage of this valve is its anti-pollution function – it protects against the backflow of dirty water or other substances harmful to human health
