Manufacturing Process
We follow a precision-controlled casting process to ensure reliability and leak-proof performance:
Precision Molding: Accurate cavity formation for consistent quality
Controlled Pouring: Defect-free castings with minimal porosity
Heat Treatment: Optimized strength, durability, and corrosion resistance
CNC Machining: Tight tolerances and smooth sealing surfaces
Final Testing: Pressure, vacuum, and leak tests for zero-defect assurance

Testing & Compliance
We ensure every breather valve casting meets global quality and safety standards through rigorous testing and compliance checks:
Dimensional Accuracy: CMM, gauges, and precision measuring tools
Non-Destructive Testing (NDT): Dye Penetrant, Radiography, and Ultrasonic inspection for defect-free surfaces and integrity
Mechanical Testing: Hardness, tensile, yield strength, elongation, and impact resistance
Chemical Analysis: Spectro analysis to verify alloy composition
Pressure & Vacuum Testing: Compliance with API 2000 / ISO 28300 for set pressure, flow, and leak-proof performance
Surface & Finish Checks: Roughness, coating adhesion, and corrosion resistance validation
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
