- Body and bonnet: Austenitic stainless steel forgings for body and bonnet provide excellent impact strength, minimal heat loss and corrosion protection. Only specially approved foundries may use cast steel valves for casting.

- Stem: To minimize wear, stem is pre-stretched in N 50(class XM-19 A479) for excellent low friction and free movement of stem contact points even at very low temperatures and without wear. Substitute 316L stem for less demanding applications.

- Components: all austenitic stainless steel, small size 1/4 "forged steel valve, seat, wedge or disc usually STL6.

- Yoke sleeve: copper.

- Lubrication: molybdenum disulfide lubricant 33 or compound grease 2.

- Packaging: Teflon or other plastic packaging is cryoprotected using an insulating gas column and graphite secondary packaging is used for fireproof operation.

- Seat face: STL is designed to prevent wear and abrasion. Other sealing materials such as PCTFE or PTFE are available for soft sealing.

- Bolt connection: hardened austenitic stainless steel.

- Welding: Nickel electrodes must be used.

- Cleaning: All cryogenic valves are degreased, cleaned and sealed to prevent contamination.
