Double-disc, flanged, straight check valve DN00 PN16 407A100C56

Check Valve – Reliable Protection for Installations

The double-disc, flanged check valve with DN100 diameter and nominal pressure PN16 is a robust solution designed to protect installations against backflow. Manufactured from GG 25 (GJL-250) cast iron, it ensures durability and corrosion resistance. The double-disc design, combined with a manual wheel, enables precise flow control and easy operation.

This valve is suitable for water, heating, and industrial systems where protection against medium reversal is required. A Kvs value of 184.7 indicates high flow capacity, resulting in minimal pressure loss within the system. The stainless steel spring ensures reliable disc closure in all operating positions and extends the valve’s service life.

Design and Functionality

Valve 407A has been engineered for easy installation and maintenance. The flanged connection simplifies integration with existing infrastructure. Additionally, the valve features measurement ports, allowing real-time monitoring of flow parameters. The valve body complies with EN558-49 standard, confirming its high quality and safe operation. The ability to operate in tandem with another valve expands its application range.

The valve serves a regulating function with flow limitation—critical in systems requiring precise control of the medium volume passing through the installation. The disc and spring, both made of stainless steel, ensure reliable performance even under demanding operating conditions.
