Engineering Steel Castings - Valve Castings
Custom Valve Castings Manufacturer
Many valve components specially the valve bodies and valve bonnets contain geometries that are difficult or expensive to manufacture by machining from bar stock, plate, or forgings. One of the most important advantages of investment casting is its ability to produce components close to their final geometry. Compared with machining a valve component from a solid block of stainless steel or alloy steel, investment casting can significantly reduce the amount of material that needs to be removed during subsequent machining.
Why use investment casting process for valve bodies and valve bonnets and other valve components?
Valve components are critical pressure-containing and flow-control parts used in demanding applications across the oil and gas, chemical processing, water treatment, power generation, marine, and general industrial sectors.
Because valve components often combine complex geometries, internal passages, sealing surfaces, mounting features, and demanding material requirements, selecting the right manufacturing process is essential to achieving the required performance, dimensional accuracy, and cost efficiency.
Investment casting, also known as lost wax casting or precision casting, is an effective manufacturing process for many valve components, particularly when the design requires complex geometry, good dimensional control, excellent surface finish, and near-net-shape production.
At Lantian investment casting foundry, who is a large scaled lost wax casting production foundation in China since 1997, investment casting can be combined with heat treatment, CNC machining, and inspection to provide finished or semi-finished valve components according to customer drawings and specifications.
Materials
Stainless Steel

What Valve Components Can Be Manufactured by Investment Casting?
Investment casting is particularly suitable for small-to-medium-sized valve components with relatively complex geometries. Depending on the design, material, size, and production requirements, typical investment-cast valve components include: Valve Bodies, Valve Bonnet and Valve Covers.
Valve body castings are among the most important applications.
Potential applications include:
- Ball valve bodies
- Globe valve bodies
- Check valve bodies
- Gate valve bodies
- Butterfly valve bodies
- Other custom valve housings
Valve bonnet castings can also be manufactured using investment casting. Depending on the design, valve bonnets may include:
- Flanged connections
- Bolt holes
- Internal cavities
- Stem openings
- Sealing areas
- Complex external profiles
