Anti-contamination check valve, EA type 3/4", F-F
The backflow prevention valve is a key element of a domestic water installation, protecting the system against contamination and unwanted reverse flow. Designed for 3/4" connections, it fits standard residential pipework and supports safe operation of appliances and heating circuits.
Engineered for water as the working medium, the valve operates at a nominal pressure of 10 bar and a maximum working temperature of 90°C, so it performs reliably in both cold and hot water systems. Belonging to acoustic group I, it keeps flow noise at a low level, which enhances comfort in everyday use. Compact dimensions with a body length of 78 mm and a 32 mm section help when space behind fixtures is limited.
Made from high‑quality materials, the backflow prevention valve offers long service life and resistance to demanding installation conditions. The G3/4 connection thread simplifies integration with existing pipework, and the straightforward inline design supports quick, predictable mounting by installers.
This 3/4" backflow prevention valve is an excellent choice for anyone upgrading a water safety valve in a domestic system and looking for a durable, quiet and dependable component for modern plumbing installations.
