Why Choose Ductile Iron Gate Valves?

Ductile iron gate valves are preferred for slurry applications due to their unique properties:

• Strength and Durability: Ductile iron is significantly stronger than traditional cast iron, making it more suitable for high-pressure environments.
• Corrosion Resistance: Many ductile iron valves come with protective coatings, which enhance their resistance to corrosion caused by aggressive materials found in slurries.
• Sealing Efficiency: The design of ductile iron gate valves allows for effective sealing, reducing the risk of leaks in systems handling slurries.

Key Features of Ductile Iron Gate Valves for Slurry Applications

Choosing the right ductile iron gate valve for slurry applications requires an understanding of its essential features:

1. Material Composition: Ensure the valve is made of high-quality ductile iron to endure the abrasive nature of slurries.
2. Seal Type: Opt for valves with resilient seals to handle the fine particles in slurry without leakage.
3. Flow Rate Control: Ductile iron gate valves typically manage high flow rates, making them suitable for large-scale slurry transport.
4. Pressure Ratings: Verify that the valve’s pressure rating meets or exceeds the project requirements.

Common Problems and Solutions

When implementing ductile iron gate valves in slurry environments, some issues may arise. Here we provide solutions to these typical problems:

• Problem: Abrasive Wear
  
  Solution: Select valves with hard-coated surfaces or internally lined materials that resist erosion from solid particles in the slurry.
