Check valve DN65, FIG.402 402A065C52

DN65 flanged check valve, type 402, is a reliable solution to protect the installation against backflow of medium. Made of gray cast iron, it ensures durability and corrosion resistance. Designed for use with water, glycol and other neutral agents, it finds application in heating, water supply and industrial systems.

Construction and materials

The valve construction is based on proven materials guaranteeing long life and trouble-free operation:

• Body: gray cast iron EN GJL-250, additionally epoxy coated for increased corrosion resistance.
• Closing and guide assembly: ductile iron EN GJS-400-14 – provides strength and precision of operation.
• Spring: stainless steel AISI302 – resistant to the action of the medium and ensures fast valve response.
• Mushroom seal: EPDM – guarantees tightness and flexibility over a wide temperature range.

Operating characteristics and advantages

The valve is characterized by low pressure losses, which translates into energy efficiency of the entire system. The possibility of mounting in any position facilitates installation and adaptation to different spatial conditions. In addition, the valve does not require maintenance, which reduces operating costs. This makes it a solution that is both economical and practical.

• Versatility: the possibility of mounting in any position allows for flexible adaptation to the installation.
• Low pressure loss: minimizes flow resistance, increasing system efficiency.
• Maintenance-free: no need for regular maintenance reduces installation maintenance costs.
• Durability: the use of high-quality materials ensures a long valve life.
• Compliance with standards: mounting between flanges Pn10/16 according to EN 1092 ensures compatibility with most standard installations.

The valve operates in a temperature range from -10°C to +80°C with a maximum working pressure of 16 bar. It is a solid and reliable device that will meet the expectations of even the most demanding users.
