Montville, New Jersey-based Marotta Controls recently announced that it has been awarded a contract from Airbus Defence and Space to provide high pressure Miniature Solenoid Valves for the Propulsion Modules of the MetOp Second Generation satellite constellation.
Marotta’s miniature solenoid valves (model MV602) are key components of the Propulsion Module (PM) and are used in a bang-bang mode to re-pressurize the propulsion module’s hydrazine tanks with gaseous Helium (GHe). These miniature, high pressure, normally closed valves are based on the highly successful model MV602L, which is a latching configuration that was flight-qualified on previous ESA missions, LISA Pathfinder and Aeolus. The MV602 and MV602L valve series have the smallest envelope and mass, and lowest power draw of any miniature latching/non-latching valves available today.
