Flap check valve 3/4" F-F
The swing check valve is designed to protect water installations against backflow and contamination, working reliably in domestic and small commercial systems. With a 3/4" connection, it fits standard pipelines and becomes a practical alternative to a 3/4 backflow prevention valve in many applications.
The robust brass body in CW617N grade handles operating pressure up to 16 bar, so the valve performs well even in demanding conditions. The internal brass closing element and NBR sealing ring create a tight shut-off for cold and hot water, supporting stable operation of the entire installation.
The nickel-free design keeps all water-contact surfaces free from nickel coating, an important aspect for drinking water systems and users sensitive to this metal. The nut-to-nut connection in G3/4 thread simplifies assembly and disassembly during maintenance, while compact dimensions help when space around the pipeline is limited.
This swing check valve is a solid choice wherever a durable 3/4 water control valve is needed and long-term reliability of the installation matters.
