Main function
The Helium Loading Plate is composed of two electro-valves and two filters. Both solenoid bi-stable valves provide a two-step smooth opening which avoids deterioration of downstream equipment.
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.
