Butterfly valves are essential for efficient fluid control. The choice of material for the valve body impacts its durability, compatibility with various fluids, and suitability for specific applications.

Cast Iron: Cast iron provides a cost-effective option for butterfly valve bodies. It performs well in water distribution systems and HVAC applications. However, it doesn’t fare well in corrosive or high-temperature environments.

Ductile Iron: Compared to cast iron, ductile iron is more flexible and impact-resistant. It is ideal for demanding applications in water treatment, fire protection, and chemical processing due to its enhanced durability and reliability.

Stainless Steel: Stainless steel stands out for its exceptional corrosion resistance. It is the material of choice for corrosive environments and is commonly used in chemical processing, oil and gas, and marine applications.

Carbon Steel: Carbon steel delivers strong mechanical properties and is suitable for high-pressure and high-temperature settings. Industries like power generation, oil and gas, and petrochemicals frequently use it.

Aluminum: Aluminum is lightweight and offers good corrosion resistance. It is commonly found in the food and beverage, pharmaceutical, and wastewater treatment industries.

Conclusion: When selecting a material for butterfly valve bodies, consider the specific application and operating conditions. Assess fluid compatibility, temperature, pressure, and corrosion resistance to make the best choice.
