Double-disc, flanged, straight check valve DN65PN16 407A065C56

Check Valve – Reliable Protection for Installations

The double-disc, flanged check valve with nominal diameter DN65 and nominal pressure PN16 ensures unidirectional flow of liquids or gases. The cast iron body with stainless steel discs and spring guarantees durability and corrosion resistance. This valve is suitable for water systems, heating systems, industrial applications, and installations requiring protection against backflow.

Construction and Operating Principle

Valve 407A features a flanged design that simplifies installation and integration into existing infrastructure. The double-disc mechanism ensures tight sealing and minimizes leakage risk. The stainless steel spring effectively presses the disc against the body, ensuring reliable operation under varying working conditions. This valve can operate in tandem with another valve and is prepared for potential expansion—though it does not directly interface with an actuator.

Key Features and Benefits

• Durability and Corrosion Resistance: Housing made of GG 25 (GJL-250) cast iron ensures strength and resistance to pressure and corrosion.
• Leak-tight Sealing: Double-disc design with stainless steel disc and spring guarantees tight closure against reverse flow.
• Easy Installation: Flanged connection enables quick and simple integration into existing systems.
• High Performance: Kvs value of 88.8 indicates high flow capacity, minimizing pressure losses in the system.
• Versatility: Suitable for use with technical water, ethylene glycol, and other neutral media.
• Standards Compliance: Dimensions conform to EN558-49, ensuring compatibility with other system components.
• Monitoring Capability: Equipped with measurement ports for monitoring flow parameters.

This valve is a robust solution for both professional installers and end-users seeking reliable protection against backflow. Its design enables operation under diverse conditions, while easy installation translates into time and cost savings during setup.
