Flap check valve 3/4" F-F

The swing check valve is a reliable component for domestic water installations, designed to prevent backflow and protect the system against unwanted reverse circulation. With a 3/4" connection, it fits standard pipelines and works well as part of safety and protection assemblies in both new and modernised installations.

The body and closing element made of CW617N brass provide high mechanical strength and resistance to corrosion, while the NBR sealing ensures tight closure under variable operating conditions. The valve operates at a nominal pressure of up to 16 bar, so it performs well in demanding water supply systems where stable parameters are essential.

The nickel‑free internal surfaces in contact with water support safer use in potable water systems and reduce the risk of nickel release. The nut‑to‑nut connection simplifies installation in confined spaces, and the compact dimensions of 56 x 38.7 mm help integrate the valve into existing pipe runs without extensive modifications.

This 3/4" check valve is a solid alternative to a standard 3/4" safety valve in installations where backflow protection is a priority and long‑term durability, easy assembly and high‑quality materials matter.
