Process Monitoring

  • The whole manufacturing process of the valves are progressively and continuously monitored as per the written procedure by performing inspection and testing at various stages of the processes such as,

    • Customer requirement evaluation and monitoring
    • Checking of incoming raw materials and certification
    • Inspection of components during in process
    • Various Pressure tests
    • Functional tests
    • Non destructive tests
    • Final inspection of finished valves
