Ductile Iron Flanged Swing Check Valve

The Ductile Iron Flanged Swing Check Valve is a highly durable and reliable valve engineered to permit fluid flow in one direction only, automatically preventing dangerous and damaging backflow within the piping system. Its robust construction and resilient swing disc make it an essential component for maintaining pipeline network integrity across numerous industries.

Key Features and Advantages

Durable Construction: Made from high-quality Ductile Iron (GGG50 or similar), providing superior strength, durability, and resistance to thermal shock and mechanical stress.
Corrosion Resistance: The ductile iron material offers excellent resistance to corrosion, further enhanced by an internal and external WRAS approved epoxy powder coating at $300$ microns thick, suitable for potable water applications.
Swing Check Design: Features a swing disc mechanism that opens with forward flow and automatically closes against back pressure, ensuring efficient flow control and preventing backflow (reverse flow).
Flange Connection: Equipped with a flange connection for easy, secure, and leak-tight installation and simple maintenance.
Leak-Tight Performance: Provides reliable leak-tight performance, essential for preventing pressure surges or water hammer.
Low Maintenance: The sturdy construction minimizes the need for frequent maintenance, reducing downtime and operational costs.
