Manufacturing Process

We use a precision-controlled casting process to ensure high-quality, durable check valve components. From accurate patterning and controlled pouring to heat treatment, machining, and rigorous inspections, every casting is leak-proof and reliable.

  • Accurate Patterning: Ensures consistent shape and quality

  • Controlled Metal Pouring: Reduces defects and porosity

  • Strengthening Heat Treatment: Enhances durability and toughness

  • Precision Machining: Smooth surfaces and tight tolerances

  • Quality Verification: Dimensional, functional, and visual inspections

Testing & Compliance

We ensure every check valve casting meets international quality, performance, and safety standards through comprehensive testing:

  • Dimensional Verification: CMM, calipers, and gauges for precise body and seat 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: Disc/seat operation, backflow prevention, hydrostatic pressure, and air tightness tests

  • Corrosion & Surface Testing: Coating adhesion, passivation quality, and optional salt spray testing

  • Standards Compliance: API 594 / 598, ASTM, ASME, DIN, EN, BS, JIS
