Pyrotechnic Valves for Space Propulsion Systems

All European, normally open and normally closed pyro valves with ESA standard initiators.

Airbus Space Systems, Lampoldshausen produces a wide range of normally open and normally closed pyro valves for a variety of applications. The main features of these valves are:

  • Redundant ESA standard initiators.
  • All welded titanium design.
  • Wide operational temperature range.
  • Adaptable tube interfaces with no impact on functional parts.
  • All European component.
