Flap check valve 1" F-F
The swing check valve is a reliable component for domestic water installations, designed to protect the system from backflow and maintain stable operation of the pipeline. It works with water as the medium and fits standard 1" connections, so it integrates easily into typical residential setups.
The durable brass CW617N body resists corrosion and mechanical wear, while the brass closing element and NBR sealing ring support tight shut-off even at a nominal pressure of 16 bar. The internal geometry is tailored for efficient water flow in everyday use, and the compact length of 64 mm helps when space in the installation is limited.
The nickel-free design stands out in this check valve: all surfaces in contact with water are free from nickel plating, which benefits users sensitive to this material and supports safe potable water systems. The nut-to-nut connection with G1 thread simplifies assembly and disassembly during maintenance or system upgrades.
This brass check valve is a solid choice for anyone building or modernising a water supply installation and looking for a durable, nickel-free solution that combines robust materials with convenient installation.
