Check valve flanged type 402 DN65 149B2283

Flanged check valve – reliable installation protection

The flanged check valve type 402, with a nominal diameter of DN65, is a safety element preventing backflow in water supply and industrial installations. The cast iron construction with epoxy coating ensures durability and corrosion resistance, while the rubber seal guarantees tightness. This model, with a pressure class of PN10 for both the device and the flange, is particularly recommended for use with pumps, where it prevents water hammer and ensures stable system operation.

Construction and application

The valve is designed to work with clean liquids and gases at temperatures from -10°C to 100°C. Its construction based on a spring-assisted poppet closure allows for effective stopping of backflow with minimal pressure loss. Thanks to the possibility of installation in any position, the valve is extremely flexible in application. It works well in pumping stations, tanks and transmission networks, where protection against contamination and damage resulting from backflow is crucial.

Key features and benefits

• Durable construction: The cast iron body coated with epoxy provides corrosion resistance and long life.
• High tightness: The rubber seal and precise poppet design guarantee reliable backflow stopping.
• Low pressure loss: The profiled body shape minimizes flow resistance, which translates into energy efficiency of the installation.
• Universal mounting: The possibility of installation in any position makes it easy to adapt to existing infrastructure.
• Protection against water hammer: Particularly recommended for operation behind a pump, where it prevents dangerous pressure surges.
• Easy maintenance: The inspection cover allows you to check the internal elements without having to disassemble the valve from the pipeline.
• Compliance with standards: Meets the requirements of the Pressure Equipment Directive (PED) 2014/68/EU and has ACS approvals.

The type 402 check valve is a solid and reliable solution for professionals and end-users looking for effective protection of their installations against the effects of backflow. Its versatility and ease of installation make it an ideal choice for a variety of applications in construction and industry.
