Check valve with plastic closing element, 1", FF
The non-return valve with plastic closing elements, 1", nut–nut connection is a compact component for domestic water installations, designed to protect the system against backflow. It works reliably in heating and water circuits using water or water-glycol mixtures, supporting stable operation of a DN25 valve line.
The valve operates at a nominal pressure of up to 16 bar and a maximum working temperature of 70°C, so it performs well in demanding conditions of central heating and utility water systems. The internal geometry is adapted to installations where a full bore is not required, which helps control flow in smaller circuits.
The body made of CW617N – 4MS brass offers high resistance to corrosion, while the ABS closing element ensures precise shut-off and quiet operation. The nut–nut threaded connection with G1 dimension simplifies assembly and disassembly during service. The Nickel Free design supports use in systems where contact with drinking water is expected.
With its durable materials, DN25 connection size and carefully selected operating parameters, this non-return valve is a dependable choice for installers looking for a robust, easy-to-mount solution for modern water and heating systems.
