Manufacturing Process
We follow a precision-controlled casting process to ensure dimensional accuracy and high strength:
Advanced Pattern Design: Ensures consistent cavity geometry for precise valve function
Controlled Pouring: Minimizes porosity, shrinkage, and internal defects
Strengthening Heat Treatment: Enhances hardness, toughness, and structural integrity
Precision Machining: Achieves smooth sealing surfaces and tight tolerances for leak-proof operation
Rigorous Inspection: Dimensional, visual, and functional checks for safety-critical performance
Testing & Compliance
We ensure every wafer type non-return valve casting meets global quality, performance, and safety standards through rigorous 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
