Check valve, double disc, wafer-style, straight DN80PN16 407A080C56

Between-flange double-disc check valve – reliable protection for installations

This double-disc check valve by Zetkama, manufactured from cast iron, is a robust solution for preventing backflow in piping systems. Designed for between-flange installation in pipelines with a diameter of DN80 and nominal pressure PN16, it ensures effective protection for pumps, equipment, and the entire network. The design features a disc and spring made of stainless steel, guaranteeing durability and corrosion resistance.

The valve has been designed in accordance with EN558-49 standard, confirming its high quality and compliance with European norms. The housing, made of GG 25 cast iron (GJL-250), offers high mechanical strength and resistance to damage. A Kvs value of 113.4 indicates high flow capacity, minimizing pressure losses in the system.

Design and application

The 407A series check valve combines proven structural solutions with high-quality materials. The valve disc, assisted by a stainless steel spring, ensures tight sealing in the reverse flow direction. A manual handle enables easy operation and visual inspection of the valve’s status. The possibility of installing short measuring nipples facilitates monitoring of system operating parameters. The valve operates in tandem with another valve, enhancing its functionality.

The valve is constructed from GG 25 cast iron, ensuring strength and corrosion resistance. The disc and spring, made of stainless steel, guarantee long-term reliability. Compliance with EN558-49 confirms the product’s high quality. The high Kvs value of 113.4 minimizes pressure drop in the system, while the between-flange mounting simplifies integration into existing pipeline infrastructure. The manual handle allows for manual operation when needed, and the option to install measuring nipples enables easy monitoring of system parameters.

This valve is suitable for a wide range of industrial and municipal installations, including water supply, sewage, heating, and process systems. It is ideal for protecting pumps, pressure reducers, and other equipment sensitive to backflow of the medium.
