Check valve DN200, FIG.402 402A200C52

Check valve – reliable installation protection

This cast iron check valve, with a nominal diameter of DN200 and designation FIG.402, is a key element in any installation where protection against backflow of medium is required. The construction provides effective protection against damage resulting from fluid backflow, and the solid design guarantees long-lasting and trouble-free operation. This valve is particularly useful in industrial, heating and marine systems.

Construction and application

The check valve from the FIG.402 series is characterized by a flanged connection, which facilitates installation and removal in existing installations. Made of gray cast iron (EN-GJL-250), it provides strength and corrosion resistance. Designed to work with various media, including glycol and industrial water (provided they are chemically neutral). It can be used in a wide range of temperatures – from -10°C to 80°C – making it a universal solution for many applications. Compliance with the pressure equipment directive 2014/68/EU and CE marking (for DN≥65) confirm its safety and high quality.

Key features and benefits

• Universal mounting: The ability to operate in any position allows for flexible adaptation to installation conditions. You don't have to worry about the valve's orientation during installation – it will work reliably regardless of how it is placed.
• Low pressure drop: The valve's design minimizes flow resistance, which translates to energy efficiency of the system and reduced operating costs.
• Maintenance-free: The valve does not require regular maintenance, which reduces costs associated with maintaining the installation and ensures its continuity of operation.
• Strength and durability: Made of gray cast iron, it guarantees resistance to mechanical damage and corrosion, ensuring a long service life of the device.
• Wide range of applications: Ideal for use in industry, heating and marine systems.
• Compliance with standards: Meets the requirements of the pressure equipment directive 2014/68/EU and has CE marking for diameters DN≥65, which confirms its safety and quality.

The FIG.402 check valve is a solid and reliable solution for professionals and end-users looking for effective protection of their installations against medium backflow.
