  1. Cryogenic Service Cold Box and Yard Valves

  2. Soft seat option provides class VI tightness V817 Cryogenic Globe Valve • Size 1”-6” • Class 150, 300, 600 • Body Mat’l: 304 Stainless Steel • End Connections: • Raised Face Flanges • Socket Weld • Butt Weld

  3. V817 Cryogenic Globe Valve Features • bolted bonnet joint that is outside of the insulated barrier • extended stainless steel body • removable trim without accessing the insulated barrier • all welded construction within the insulated barrier

  4. G120 Cryogenic Globe Valve Features • post guided plug • extended stainless steel body • easily accessed seat ring Typically used for ‘warm service’ • Yard valves • Outside of ‘cold box’

  5. V815 Series • Similar to V817 except; • Special face-to-face dimensions • Weld-on flanges • Available with bronze body • Was used by only Air Products • Offer V817 unless APCI or direct replacement

  6. Cryogenic Air Separation • Air Feed • Air is drawn into the plant by main air compressor. • Cleaning • The air goes through a filter house to remove dust and large particles. • The air is then cooled and cleaned of CO2 and moisture by passing it through a molecular sieve drier.

  7. Cryogenic Air Separation • Compressing • The air is compressed to high (150 psi) pressure for expansion. • Cooling • The cool and dry air is then cooled even further to -300°F (-185°C) in the main heat exchangers and is then sent to the distillation column.

  8. Cryogenic Air Separation • Separation • The air is separated into its elemental components in the form of liquid oxygen, argon and nitrogen, based on its different boiling points. • The more volatile components, nitrogen, will rise up and oxygen will go down while argon will be somewhere in between.

  9. Cryogenic Air Separation • The pure products are drawn off to: • store in cryogenic storage tank, • deliver to the customers by liquid tanker • or pure products are feed to customer by pipeline network.

  10. Valtek • Mark Six • Integral seat • Threaded available • Now used by Air Products

  11. Samson • Model 3248 • Standard bellows seal prevents stem leakage • Now used by Praxair
