Our Valve Casting Manufacturing Capability
Valve Sand Casting
Sand casting uses sand molds with cavities to pour molten metal. It is more suitable for larger valve components. Unlike investment casting, its maximum casting weight can be up to 2 tons. However, it requires more machining allowances for subsequent processing operations.
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
Investment casting is a traditional metal casting method suitable for producing complex cast steel valves, such as butterfly valves and ball valves. Investment casting ensures excellent dimensional accuracy, tolerances, and surface finish.
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, also known as gravity die casting, utilizes reusable metal molds to produce high-quality valve castings. This method is particularly well-suited for manufacturing valve components from non-ferrous metals, with brass and aluminum alloys being the most common choices. The reusability of the molds makes this process cost-effective, especially for large-scale production, while ensuring consistent quality in every batch.
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 is ideal for producing precision cast iron valve components, offering excellent surface finish and dimensional accuracy. Valve castings made with this method are typically close to net shape, requiring minimal to no further machining, which reduces production time and costs.
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.

Valve Casting Manufacturers: Pressure Testing and Nondestructive Testing
At Leierwo Casting, we ensure that our valve castings undergo rigorous pressure testing to verify their performance under demanding conditions. Additionally, we perform non-destructive testing (NDT) methods, such as ultrasonic testing (UT) and magnetic particle testing (MT), to guarantee the integrity and quality of every valve casting. These testing processes ensure that all our manufactured products are leak-free and meet the highest industry standards.
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.
