Our Valve Casting Manufacturing Capability
Valve Sand Casting
Certain types of valve bodies are typically produced by sand casting instead of investment casting, mainly due to considerations of size, cost, and materials. Typical sand cast valve types include:
Ball Valves: Large ball valves are usually produced by sand casting.
Gate Valves: Used in the oil and gas industry, sand casting is suitable for large gate valves.
Butterfly Valves: For large diameters, sand casting can produce large and complex shapes at a lower cost.
Pressure Relief Valves: Commonly used in high-pressure applications, sand casting ensures durability.
Relief Valves: Used to regulate pipeline flow.
Valve Investment Casting
Ball Valves: Medium to small-sized ball valves, especially those requiring strict tolerances, are typically made using precision casting.
Control Valves: The complex internal structure of control valves is well-suited for precision casting.
Safety Valves: For critical components in industrial protection, precision casting ensures reliability.
Check Valves: Small check valves used in high-precision systems, such as hydraulic or pneumatic systems, are produced through precision casting.
Globe Valves: Small globe valves requiring strict dimensional tolerances are often made using precision casting.
Permanent Mold Casting
Compared to investment casting, permanent mold casting offers faster production speeds, making it an efficient solution for meeting high-volume demands. While sand casting and investment casting are ideal for complex designs and smaller quantities, permanent mold casting is the preferred choice for valve castings when large quantities are needed and consistency is critical.
At Leierwo Casting, we leverage permanent mold casting to deliver durable, precise, and cost-efficient valve castings tailored to meet the specific requirements of our clients. Whether for industrial, automotive, or commercial applications, our valve castings provide reliable performance and exceptional value.
Lost Foam Casting
The process involves creating a foam pattern, coating it, and embedding it in sand. Molten metal is then poured in, vaporizing the foam to form the final casting. This ensures intricate designs and consistent quality.
At Leierwo Casting, we use lost foam casting to deliver high-precision, durable, and cost-effective valve castings for industries like oil and gas, water treatment, and industrial machinery. Our advanced techniques ensure reliable performance and exceptional value.
Valve Casting Manufacturers: Pressure Testing and Nondestructive Testing
Our valve castings are produced using the silica sol casting process, which ensures excellent surface finish and dimensional accuracy. This advanced technique allows us to meet precise drawing requirements solely through casting, often eliminating the need for additional machining. As a result, our customers receive valve castings with unparalleled surface finishes and top-quality performance.
Trust Leierwo Casting to deliver reliable, high-performance valve castings tailored to your specific needs, backed by our commitment to quality and precision.
