Check valve DN125, FIG.402 402A125C52

Check valve – reliable protection for the installation

The check valve DN125, designated as fig. 402, is a component that protects the installation against backflow of medium. Made of durable grey cast iron, it ensures long-lasting and trouble-free operation in various conditions. It is a key component in heating, industrial and water installations where maintaining the correct flow direction is necessary.

Construction and application

This valve is characterized by a flanged connection, which facilitates assembly and disassembly in existing installations. It is designed to work with media such as glycol, industrial water and chemically neutral agents. Thanks to its construction, the valve works well in the shipbuilding industry, district heating and many other industrial 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

• Versatility: The ability to mount in any position makes the valve easy to adapt to different installation layouts.
• Low flow rate: The design minimizes pressure loss, which translates into energy efficiency of the system.
• Maintenance-free: The valve does not require regular maintenance, which reduces operating costs and ensures continuity of operation.
• Durability: Made of grey cast iron (EN-GJL-250) guarantees resistance to corrosion and mechanical damage.
• Wide temperature range: The ability to operate in a temperature range from -10°C to 80°C allows the valve to be used in various environmental conditions.
• Safety: CE marking confirms compliance with European safety standards.

The check valve fig. 402 is a solid and reliable solution for professionals and end-users looking for effective protection of the installation against backflow of medium. Its simple construction and lack of maintenance make it a practical choice for a wide range of applications.
