Cobham

The most important thing we build is trust

 

Cobham’s advanced Electric Propulsion Xenon Regulator, used to regulate pressure on satellite propulsion systems, features significantly higher flow rates in the smallest most lightweight envelope possible.

The Xenon regulator is arranged in a series redundant configuration to ensure continued system function should either stage fail open. This arrangement is dictated by the application for which high operational reliability is required.

 

Extremely low external leakage performance is achieved by employing welded closures to all external leak paths. The low weight of the regulator stems from optimal design and packaging of components around customer requirements.
