Double-flow, between-flanges, straight check valve DN200PN16 407A200C56

Check Valve – Reliable Protection for Systems

This double-disc check valve, constructed from durable cast iron, is a critical component in any system requiring protection against backflow. Its flange-to-flange design, compliant with DN200 and PN16 standards, ensures easy installation and seamless integration with existing systems. This valve is widely used across industrial and municipal installations, delivering efficient performance and long-term reliability.

The 407A valve features a robust construction: the body is made from high-grade cast iron GG 25 (GJL-250), while the disc and spring are crafted from stainless steel, ensuring excellent corrosion resistance and extended service life. The stainless steel spring guarantees secure disc closure in any operating position, resulting in stable and consistent performance. The valve complies with EN558-49 standards, confirming its quality and safety.

• Durable Construction: Cast iron body provides high resistance to pressure and mechanical damage.
• Corrosion Resistance: Stainless steel disc and spring ensure long-term operation even under harsh conditions.
• Easy Installation: Flange-to-flange design simplifies integration into existing piping systems.
• High Flow Capacity: Flow coefficient Kvs of 710.0 ensures minimal pressure drop.
• Monitoring Capability: Equipped with measurement ports for monitoring flow parameters.
• Paired Operation: Can be installed in tandem with another valve for enhanced system control.

This valve is not designed for automated expansion or integration with actuators, making it ideal for simple, manually operated systems. Its flow-restricting regulation function enables precise control of the medium within the system. Additionally, the absence of a blowoff function and the ability to operate in tandem with another valve enhance its versatility.
