Check valve with plastic closing element, 3/4", FF
The non-return valve with plastic closing elements, 3/4", nut–nut connection is a compact component for domestic water installations. It protects the system against backflow, stabilising operation of devices such as boilers, pumps or heating circuits.
The valve is designed for media such as water and mixtures with up to 50% glycol, so it fits both standard plumbing and central heating systems. A nominal pressure of 16 bar and a maximum operating temperature of 70°C support reliable performance in demanding conditions, while the DN 20 connection matches typical DN20 valve installations.
The body made of CW617N brass in 4MS quality offers high resistance to corrosion, and the ABS closing element ensures precise shut-off. The nut–nut connection in G 3/4 thread simplifies assembly and disassembly during service work. The Nickel Free design supports use in systems where contact with drinking water is expected.
This non-return valve is a practical choice for installers and homeowners looking for a durable DN 20 check valve that supports safe, long-term operation of the entire installation.
