Manufacturing Process
We follow a precision-controlled casting process to produce safe, leak-proof safety valve components. Every step is optimized to ensure reliability and long-term performance.
Optimized Mold Design: Guarantees uniform cavity shapes and accurate dimensions
Controlled Metal Flow: Reduces turbulence, porosity, and shrinkage defects
Stress-Relieving Heat Treatment: Improves toughness, durability, and structural integrity
High-Precision Machining: Ensures smooth sealing surfaces and exact tolerances
Comprehensive Inspection: Dimensional, visual, and functional checks for secure, reliable operation
Testing & Compliance
We ensure every safety valve casting meets international quality, performance, and safety standards through rigorous testing:
Dimensional Verification: CMM, calipers, and gauges for precise body, spring, and disc alignment
Non-Destructive Testing (NDT): Dye Penetrant, X-ray, and Ultrasonic inspection for internal and surface defects
Mechanical & Metallurgical Tests: Hardness, tensile strength, yield strength, elongation, and microstructure analysis
Functional Testing: Pressure relief operation, disc and spring performance, hydrostatic pressure, and air tightness tests
Corrosion & Surface Testing: Coating adhesion, passivation quality, and optional salt spray testing
Standards Compliance: API 520 / 526, ASTM, ASME, DIN, EN, BS, JIS
