Space equipement - Safran Aero Boosters - VP - Vinci Engine.

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.
