Check valve with brass closing element, 1 1/2", FF
The non-return valve with brass closing elements 1 1/2", nut–nut connection is a reliable component for domestic and technical water installations. It protects the system against backflow and supports stable operation of pumps, boilers and distribution manifolds in everyday use.
Designed for media such as water and mixtures with up to 50% glycol, the valve works safely at a nominal pressure of 16 bar and a maximum operating temperature of 120°C. The DN 40 connection and G 1 1/2 thread fit typical pipeline dimensions, so the product integrates well with standard shut-off and control valves in the installation.
The body made of CW617N 4MS brass and a brass closing element form a durable, corrosion-resistant construction suitable for long-term operation. The nut–nut connection simplifies assembly and disassembly during service, while the compact dimensions of around 68 x 73 mm help when space around the pipeline is limited. The nickel-free design reduces contact with nickel, which is important for sensitive users.
This brass non-return valve is a solid choice for professional installers and demanding homeowners who expect dependable backflow protection and easy integration with existing DN 40 piping.
