The non-return valve with a brass closing element is a reliable component for domestic water installations, protecting the system against backflow and helping maintain stable operating conditions. With a 3/4" connection, it fits common installation standards and works well as part of a 3/4 backflow protection valve setup.
The robust CW617N brass body is resistant to corrosion and mechanical wear, so the valve keeps its tightness even at a nominal pressure of 10 bar. The internal surfaces in contact with water are nickel free, an important feature for users who expect safer materials in potable water systems.
The brass closing element provides precise shut-off, while the nut-to-nut connection simplifies assembly in existing pipe runs. Compact dimensions of around 42 x 51 mm help when space is limited, for example near a 3/4 safety valve or other fittings in a technical room.
This non-return valve is a solid choice for professional and home installers who value durable brass construction, straightforward installation, and dependable protection of the water system against reverse flow.
