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 tools for exact body, chamber, and port alignment

  • Non-Destructive Testing (NDT): Dye Penetrant, Radiography, and Ultrasonic inspection for defect-free surfaces and structural integrity

  • Mechanical Testing: Hardness, tensile strength, yield strength, elongation, and impact resistance to ensure durability under operational stress

  • Chemical Analysis: Spectro analysis to verify alloy composition and material compliance

  • Pressure & Flow Testing: Verification of leak-proof performance, flow accuracy, and compliance with API 674 / ISO 2858 standards

  • Surface & Finish Checks: Surface roughness, coating adhesion, and corrosion resistance for long-term reliability
