Check valve with plastic closing element, 2", FF
The non-return valve with plastic closing elements, 2", nut–nut connection is a reliable component for water and heating installations. It protects the system against backflow, stabilises operating conditions and supports safe work of pumps and other devices in domestic and light commercial systems.
Designed for media such as water and mixtures with up to 50% glycol, the valve suits both standard water supply and closed heating circuits. The nominal pressure of 16 bar fits demanding installations, while the maximum operating temperature of 70°C matches typical system parameters. The DN 50 connection size responds to projects requiring a robust 2" check valve.
The body made of CW617N – 4MS brass offers high resistance to corrosion, and the ABS closing element keeps the internal mechanism light and durable. The nickel-free design supports use in systems where contact with nickel coatings is not desired. The nut–nut connection with G2 thread simplifies assembly and disassembly during service work.
This DN 50 non-return valve is a solid choice for installers looking for a durable, easy-to-mount check valve for water and glycol systems, ready for long-term, trouble-free operation.
