Castings for Different Valve Types
Different valve designs require different body shapes, closure components and assembly interfaces. We review each casting against the specified valve configuration and service requirements.
Gate Valves
Body, bonnet and wedge castings for suitable gate valve designs, with attention to internal geometry, guide features and assembly connections.
Butterfly Valves
Body and disc castings with defined shaft interfaces, seating geometry and connection features for the specified valve configuration.
Ball Valves
Cast bodies and end caps with internal features, mating surfaces and pipe connections produced according to the assembly design.
Check Valves
Body, cover and disc castings for suitable check valve configurations, with component geometry matched to the intended closing mechanism.
Materials for Valve Castings
Material selection depends on the fluid, design pressure, design temperature, corrosion conditions and valve specification. The required grade, heat treatment and supply availability are confirmed during project review.The components listed are examples. Suitability for a pressure or temperature rating depends on the specified material grade, component design and applicable requirements.
| Material | Selection Considerations | Typical Components | ||||||
| Grey Iron | Good castability and machinability for applications permitted by the valve design and service conditions. | Selected valve bodies, covers and handwheels. | ||||||
| Ductile Iron | A balance of strength and ductility for suitable water and general-service valve designs. | Valve bodies, bonnets, gate wedges and butterfly discs. | ||||||
| Carbon Steel | Material grade and heat treatment selected to meet the specified mechanical properties and service requirements. | Valve bodies, bonnets, end caps and yokes. | ||||||
| Stainless Steel | Corrosion resistance selected according to the specific fluid, temperature and operating environment. | Valve bodies, bonnets, discs and end caps. |
From Cast Shape to Machined Component
The production route is selected according to the material, internal passages, component geometry and order quantity. Casting and machining are considered together to address the shape and functional features of the finished component.

Our Main Casting Processes
Inspection to Your Valve Specifications
Our inspection capabilities include chemical composition analysis, tensile strength, yield strength, elongation and hardness testing, as well as non-destructive testing. The inspection scope is agreed according to the material grade, component drawing and customer requirements.
Chemical Composition
Chemical analysis checks the alloy composition against the specified material requirements.
Mechanical Properties
Tensile strength, yield strength, elongation and hardness are tested as applicable to the material grade and agreed inspection plan.

Valve Casting FAQs
Can you manufacture castings to our valve drawings?
Yes. We review custom valve casting projects based on your component drawings, material specifications and quantity requirements. If machining is required, please include the finished-part drawing with critical dimensions, tolerances and surface finish requirements.
Which material should we specify for our valve components?
Material selection depends on the fluid, design pressure, design temperature, corrosion conditions and applicable valve specification. Share the required material grade and service conditions so that we can review manufacturing suitability and supply availability.
Can you machine sealing and connection features?
Yes. Machining requirements can be reviewed together with casting. Please identify the required flange faces, seat recesses, stem or shaft bores, threaded connections and other functional features on the drawing.
How are pressure and leak testing requirements handled?
Please provide the required test procedure, acceptance criteria and delivery condition. Test feasibility, the stage at which testing is required and responsibility for carrying it out must be confirmed in the agreed supply scope.
