Manufacturing Process
We follow a precision-controlled casting process to ensure dimensional accuracy and high strength:
- High-Precision Molding: Ensures uniform cavity shapes and repeatable quality
- Controlled Pouring: Minimizes shrinkage, porosity, and turbulence defects
- Heat Treatment: Enhances hardness, grain structure, and mechanical properties
- CNC Machining: Delivers tight tolerances and smooth sealing surfaces
- Final Inspection: Dimensional and visual checks to ensure zero-defect output

Testing & Compliance
We adhere to stringent quality protocols to ensure every ball valve casting meets international specifications:
- Hydrostatic Testing: Pressure integrity validated up to 1.5x rated pressure
- Air Leak Testing: Ensures no internal porosity or gas escape
- Dye Penetrant Testing (DP): Detects surface cracks or defects
