Valve Applications

The application and the process fluid characteristics given by the Customer are the main factors in selecting a valve type and construction materials: clean fluids generally allow a wide range of valves and materials, while for dirty fluids and high risk applications the choice is limited to few valve types and selected materials.

> Hydrocarbons (Oil, Gas, derivatives)

> Utility (Water, Air, Nitrogen, Hydraulic Oils)

> Corrosive & Dirty (severe abrasive services in Sour, Sandy, Slurry, Fouling, Solidifying conditions)

> High Temperature (≤ 1000°C)

> Low Temperature (-45°C < t > 0°C)

> Cryogenic (≥ -196°C)

> High Pressure (≤ 1500 bar)

Thanks to a cooperation with Research Centres and Laboratories the following Destructive Examinations can be also performed according to customer’s and project requirements:

> Mechanical and Impact test down to –196°C

> Chemical analysis check

> Corrosion tests

> Micro examinations by electronic microscope up to 500x magnifications

> Hydrogen-Induced Cracking test (HIC) & Sulphide Stress Corrosion Cracking (SSCC)
