Check valve with brass closing element, 1 3/4", FF
The non-return valve with brass closing elements 1 1/4", nut–nut is a reliable component for domestic and light commercial water installations. It protects the system against backflow and supports stable operation of pumps, heating circuits and other hydraulic devices.
The valve is designed for a nominal pressure of 16 bar and a maximum working temperature of 120°C, so it performs well in demanding heating and water systems. The DN 32 connection with G 1 1/4 thread fits common installation standards, and the internal design is adapted to water and installations with up to 50% glycol, often used in central heating.
The body made of CW617N 4MS brass offers high resistance to corrosion, while the brass closing element ensures consistent tightness over time. The nickel-free design is suitable for users who avoid nickel-plated components. The nut–nut connection simplifies assembly and disassembly during service work, even in tighter spaces defined by dimensions around 60 mm.
This non-return valve is a solid choice for installers looking for a durable DN 32 check valve for heating and water systems, combining robust materials, safe operating parameters and convenient installation.
