Others functions
The Oxygen Chamber Valve (VCO) is integrated into the Vinci engine of the Ariane 6 upper stage. The VCO provides very low propellant leakage tightness under cryogenic conditions and at the same time a very low pressure drop in open position.
Design, development, assembly & testing of flow regulation valves for space launcher engines and stages.
Safran Aero Boosters specializes in flow regulation valves for space propulsion. With a strong focus on Research and Technology, the company is a partner on most future European launcher propulsion programs. Safran Aero Boosters’s equipment is developed under extreme conditions of temperature, pressure, vibration and flow and has demonstrated 100% reliability over 45 years. The company is able to hardness this high-level expertise to provide flow regulation valves (pneumatic/electric – linear/rotative) for most of propulsion systems on launchers.
