Check valve with plastic closing element, 2 1/2", FF
The non-return valve with plastic closing elements, 2 1/2", nut–nut connection is designed to protect installation lines against backflow in domestic and light commercial systems. It works with water and installations filled with up to 50% glycol, so it fits both standard water supply and heating circuits.
The valve is adapted to a nominal pressure of 10 bar and a maximum operating temperature of 70°C, which supports stable performance in typical building installations. The DN 65 connection and G 2 1/2 thread suit larger pipe diameters, while the internal design without full bore is tailored to controlled flow conditions in the system.
The body made of CW617N – 4MS brass offers high resistance to corrosion, and the ABS closing element ensures precise shut-off. The nickel-free finish benefits users sensitive to nickel and fits projects where material safety matters. The nut–nut connection shortens installation time and simplifies disassembly during service.
This non-return valve is a solid choice for professional installers looking for a reliable check valve for larger-diameter lines, combining durable materials, convenient mounting and parameters aligned with modern water and heating installations.
