Space propulsion
The EVB8 is a solenoid bi-stable valve designed to operate with different fluids, including cryogenic propellants. It ensures the function of bearing chill down valves for the turbo-pump of the Vinci engine and manage the propellant for the stage on the Ariane 6 launcher.
Space propulsion
The engine EV box is made of 6 normally closed electro-valves providing a gas flow to the user when activated by an electrical command. It is a power-amplified device, composed of a power stage driven by a pilot stage, actuated by a redundant electrical solenoid.
Space propulsion
The FLPP Hydrogen Chamber Valve (HCV) is an electrical poppet valve designed to work with gaseous hydrogen and driven by a brushless geared electrical motor. It has been successfully tested on the ETID engine demonstrator.
Space propulsion
The FLPP Purge Valve is a propellant assisted solenoid bi-stable valve designed to operate with different fluids, including cryogenic propellants.
Space propulsion
The Thrust Control Valve (TCV) is an electrically controlled regulation valve.
Space propulsion
The Helium Filling Valve (VRE) is part of the liquid He subsystem (SSHeL) of Ariane 5 and Ariane 6 launchers. The main function of the VRE is to open on demand to allow a refill of the Helium tank.
Space propulsion
The Helium Loading Plate composed of two electro-valves and two filters is positioned between the high-pressure helium vessels and the pressure regulator of the Ariane 6 upper stage.
Space propulsion
Safran designs and builds a wide range of plasma thrusters and complete propulsion subsystems covering the entire lifecycle of a satellite, from orbital positioning to deorbiting.
Space propulsion
This valve operates as propellant chamber valve for the Prometheus engine, on both oxygen and methane sides. This ball valve allows the propellant flow regulation thanks to its motorized geared electrical actuator as well as the propellant tightness in closed position.
Space propulsion
This box is made of 3 normally closed direct drive electro-valves providing a nitrogen gas flow when activated by an electrical command. The baseplate integrates three identical, two-ways direct drive EVs, consisting in three screwed mono-stable solenoid actuators.
