Check valve with brass closing element, 2",FF
The non-return valve with brass closing elements 2", nut-nut is a robust component for water and heating installations, designed to protect the system from backflow. It works reliably in domestic and light commercial systems where stable operation of a DN 50 valve is required.
The valve operates at a nominal pressure of 16 bar and a maximum working temperature of 120°C, so it copes well with demanding conditions in hot water and central heating circuits. It is suitable for water and installations with up to 50% glycol, which broadens its use in mixed and antifreeze-protected systems.
The body made of CW617N – 4MS brass and a brass closing element provide high resistance to corrosion and mechanical wear, extending service life. The nut-to-nut connection with G2 thread simplifies assembly and disassembly during maintenance, while the nickel-free design supports use in systems where contact with nickel is undesirable.
This DN 50 non-return valve is a dependable choice for installers and investors looking for durable brass fittings that support safe, long-term operation of water and heating installations.
