Check valve with plastic closing element, 4" F-F

The non-return valve with a plastic closing element is a reliable component for water installations, protecting the system against backflow and helping maintain stable operating conditions. It works in domestic and light commercial networks where consistent performance and long service life are expected.

The robust CW617N brass body resists corrosion in contact with water, while the ABS closing element ensures precise shut-off and smooth operation of the check valve. The valve operates safely at a nominal pressure of 10 bar, so it fits typical cold and hot water supply systems and supports secure water flow control.

The 4" nut-to-nut connection with G4 thread dimension facilitates installation in larger pipelines and existing plumbing layouts. Nickel-free internal surfaces remain free from nickel coating, an advantage for drinking water applications and users sensitive to this material. Compact body proportions support use in technical rooms and confined installation spaces.

This brass non-return valve is a solid choice for professional installers and demanding users who value durable materials, dependable backflow prevention, and a well-designed water installation.
