Playing the Testing Game in Valves – Cryogenic Testing

When it comes to testing cryogenics valves, it is done at temperatures down to -196°C (-321°F) – the boiling-point of liquid nitrogen. As its name implies, cryogenic valves are designed to be used in cold applications predominantly Liquefied Natural Gas (LNG) or Compressed Natural Gas (CNG). The parameters of testing measure leakage for seats and body, operating torques, and cycling under typical low temperatures or cryogenic conditions.
