Quality Management

From its foundation in 1992 Arako has been operating a separate Quality Control Department. The specialists supervising the product and service quality have a many years’ practice in the industrial valve production and receive regular training.

Production Process Control

The manufacture of high-quality products is ensured by the inspection mechanisms at all production process levels:

  • Inspection of materials and purchased valve fittings
  • Visual and dimensional inspection
  • Mechanical and laboratory testing (tensile tests, notch toughness tests, hardness tests, roughness tests, metallographic examinations)
  • Non-destructive testing (X-ray examinations, gamma radiographic examinations, ultrasonic examinations, liquid penetrant inspections, helium leakage tests, visual check)
  • In-process and final inspection of components
  • Inspection of valve assembly and pressure tests
  • Final inspection of products
