In focus…Cryogenic valves in aerospace applications

0

When it comes to the use of valves in aerospace applications, you probably think of diminutive sizes used in flying equipment such as R&D launchers, satellites or rovers.

These types of components usually require extensive development work and small quantities in production for prototypes or testing purposes, perhaps resulting in just one or a handful of units for the operation itself. Only satellite launchers might require the higher quantities that are of interest to an OEM of serial valves. 

Yet demand is far higher when it comes to ground operations. Cryogenic valves are mainly used for launcher filling or rocket engine test benches. Typical media are oxygen and hydrogen at cryogenic or ambient temperatures, depending on the position along their supply line. Helium may also be used for purging, and nitrogen for additional fire protection, but both in comparably smaller quantities than the combustibles.
