CARILO casting ball valves are engineered for reliable flow control in oil, gas, power, and chemical industries. With a robust casting body, they provide high strength, cost efficiency, and excellent sealing performance. Each valve is designed to resist corrosion, withstand high pressure, and ensure smooth operation in demanding environments.
Compact in structure yet durable in service, our casting ball valves offer long-term reliability for critical industrial applications. Every valve is strictly tested to guarantee safety, stability, and consistent performance.
Casting vs. Forged Structure
Casting ball valves are produced by pouring molten metal into a mold, allowing complex shapes and larger sizes to be manufactured efficiently. Compared with forged valves, casting valves offer cost advantages, design flexibility, and are widely used in medium- and low-pressure applications. The casting process enables the production of valves with intricate internal passages while maintaining structural integrity. Though forged ball valves may provide higher density and strength for extreme conditions, casting ball valves deliver an excellent balance of performance, reliability, and affordability, making them a preferred choice for distributors and EPC contractors requiring high-quality valves at competitive costs.
Material Options
Casting ball valves can be produced in a wide range of materials, including carbon steel, stainless steel, duplex stainless steel, and special alloys. This flexibility allows them to meet diverse requirements across oil, gas, power, and chemical industries. Carbon steel casting offers strength and economy, stainless steel ensures excellent corrosion resistance, while duplex and alloys handle aggressive environments with high chloride or acidic content. CARILO carefully selects and tests materials to ensure consistent casting quality, minimizing porosity and defects. By tailoring material selection to service conditions, casting ball valves provide optimal durability, sealing performance, and lifecycle cost-efficiency.
Pressure & Temperature Range
Casting ball valves are engineered to perform under a wide range of pressure and temperature conditions. Typically suitable for Class 150 to 600 ratings, they provide safe and reliable shutoff in medium-duty operations. Through precision casting techniques and advanced heat treatment, these valves maintain strength and sealing performance even under elevated temperatures. For applications where extreme pressure or temperature is not the primary challenge, casting ball valves offer an ideal solution, combining cost-effectiveness with reliable performance. This makes them a practical choice for large-scale projects where both budget and functionality must be balanced.
Design Flexibility & Size Range
The casting process allows manufacturers to produce ball valves in larger sizes and more complex geometries compared to forging. This means casting ball valves are widely available from small bore to large diameter, meeting different project specifications. Larger casting ball valves are especially favored in pipelines, refining plants, and chemical facilities where flow capacity is critical. CARILO’s casting process ensures smooth surface finish, accurate dimensions, and consistent wall thickness, which enhances valve integrity and minimizes leakage risk. The ability to accommodate various design requirements makes casting ball valves a versatile solution for distributors and EPC contractors worldwide.
Applications in Oil, Gas & Chemicals
Casting ball valves are extensively applied in upstream, midstream, and downstream oil & gas facilities, as well as in power generation, petrochemical plants, and general chemical processing. They are particularly valued in medium-pressure pipelines, utility systems, and refining units where reliable shutoff and cost efficiency are essential. Their corrosion-resistant material options allow safe handling of crude oil, natural gas, water, steam, and various chemicals. By balancing technical performance with economic benefits, casting ball valves have become one of the most widely used valve types in global industrial projects, trusted by distributors, stockists, and EPC contractors alike.
