Check valve with brass closing element, 3/4", FF
The brass non-return valve 3/4", nut–nut, is a reliable component for domestic and light commercial water installations. It protects the system against backflow and keeps the medium moving in the intended direction, supporting stable operation of heating circuits and general plumbing.
Designed as a DN20 check valve, it works with water and mixtures containing up to 50% glycol, so it fits both standard water systems and many heating applications. The valve operates at a nominal pressure of 16 bar and a maximum working temperature of 120°C, which suits demanding conditions in closed installations.
The body made of CW617N – 4MS brass and a brass closing element provide high resistance to corrosion and mechanical wear. The nut–nut connection with G 3/4 thread simplifies assembly and disassembly during service, while the compact dimensions support installation in tighter spaces. The Nickel Free design is an advantage wherever contact with drinking water is expected.
This non-return valve is a solid choice for installers and users who expect durable brass fittings, secure backflow protection and easy integration with standard 3/4" heating and water supply systems.
