Manufacturing Process

We use a controlled investment casting process to produce high-quality, leak-proof wafer type non-return valve components, ensuring reliability and long-term durability.

  • Optimized Mold Design: Guarantees uniform cavity shapes and consistent casting quality

  • Controlled Metal Flow: Reduces shrinkage, turbulence, and internal defects

  • Durability-Enhancing Heat Treatment: Improves hardness, toughness, and structural integrity

  • Precision CNC Machining: Achieves smooth sealing surfaces and exact tolerances

  • Comprehensive Quality Checks: Dimensional, visual, and functional inspections to ensure leak-proof operation under backflow conditions

Testing & Compliance

We ensure every wafer type non-return valve casting meets global quality, performance, and safety standards through comprehensive testing:

  • Dimensional Accuracy: CMM, calipers, and gauges for precise body, disc, and seat alignment

  • Integrity & Defect Inspection: Dye Penetrant, Magnetic Particle, and X-ray tests for surface and internal flaws

  • Mechanical & Metallurgical Analysis: Hardness, tensile strength, yield strength, elongation, and microstructure evaluation

  • Operational & Functional Testing: Disc operation, backflow prevention, hydrostatic and air tightness tests

  • Corrosion & Surface Evaluation: Coating adhesion, passivation, and optional salt spray resistance testing

  • Standards Compliance: API 609 / 598, ASTM, ASME, DIN, EN, BS, JIS
