Why is copper used in cryogenic valves?
The rigidity of copper is better, and the friction parts are not easy to produce adhesion. The influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Copper, which is rarely available, is easily deformed at low temperatures and is much more WCB or WCC.Below -46 degrees C, SA352, LCB.LCC
