About Cast Iron Valves
What Is Cast Iron and Why Is It Used in Valves?
Cast iron is a group of iron-carbon alloys with a high carbon content, typically above 2%. It is commonly used in valve manufacturing due to its excellent castability, vibration damping, and cost-effectiveness. Cast iron is strong in compression and performs well in low to medium-pressure applications, especially where corrosion resistance is not the primary concern.
Why Cast Iron for Valves?
- Economical: Lower cost material, ideal for budget-sensitive projects.
- Good Wear Resistance: Handles repetitive use in systems with minimal pressure fluctuations.
- Excellent Castability: Easily formed into complex shapes, making it ideal for large valve bodies.
- Vibration Damping: Reduces noise and vibration in pipeline systems.
Common Applications of Cast Iron Valves
- Water Distribution Systems: Ideal for municipal waterworks and potable water pipelines.
- HVAC Systems: Used in heating and cooling systems in commercial buildings.
- Fire Protection Systems: Frequently used in sprinkler and standpipe systems.
- General Industrial Use: Where moderate pressure and non-aggressive media are involved.
- Pulp & Paper, and Mining: In non-corrosive slurry and wastewater systems.
