Series D Ductile Iron
Frame 17 - 2024-12-30T192046.501

Series D Ductile Iron

The Series D Swing Check Valves in Ductile Iron are engineered to prevent backflow and ensure the proper flow of fluids in various industrial applications. These valves feature a swing check mechanism, which uses a hinged disc to block reverse flow when the pressure drops, thereby protecting the system from potential damage due to backflow. Constructed from ductile iron, these valves offer a balance of strength, durability, and corrosion resistance in challenging environments.

Specifications

  • Material: Ductile iron for enhanced durability, impact resistance, and corrosion resistance compared to traditional cast iron.
  • Pressure Rating: Available in ANSI Class 150, 300, and 600 pressure ratings, suitable for a wide range of industrial applications.
  • Size Range: Typically available from 2″ to 36″ in diameter, providing versatility for various system sizes.
  • Temperature Range: Effective in temperatures ranging from -20°C to 120°C, depending on the sealing material and configuration.
  • End Connections: Flanged or butt weld connections for easy installation into different piping systems.
  • Flow Direction: Prevents backflow by allowing only forward flow, protecting downstream equipment and ensuring system efficiency.
  • Actuation: Operates automatically with the flow, requiring no external power or complex mechanisms.

Description

  • Swing Check Design: The swing check valve features a hinged disc that opens when flow is in the correct direction and closes when flow reverses, preventing backflow and protecting the system.
  • Ductile Iron Construction: Made from ductile iron, these valves offer higher tensile strength and improved resistance to cracking compared to traditional cast iron, providing enhanced durability in demanding applications.
  • Flanged or Butt Weld Connections: Available with flanged or butt weld end connections, ensuring ease of installation into existing piping systems.
  • Automatic Operation: No external power source or actuation is required. The valve operates automatically with the flow, making it simple to install and maintain.
  • Corrosion Resistance: Ductile iron construction provides resistance to rust and corrosion, extending the lifespan of the valve even in harsh environments like water and wastewater systems, as well as chemical processing.
  • Compact and Reliable: Compact design allows for easy installation, while the swing check mechanism offers reliable performance for long-term use.
  • Low Maintenance: Designed for minimal wear, these valves require less maintenance compared to other types of check valves, offering reduced downtime and lower maintenance costs.
