Helium Filling Valve (VRE)
Helium Filling Valve (VRE)
Mass 2.25 kg
Operating temperature 4K - 370K
Fluid compatibility LHe, GHe, GN2
Flow rate 100g/s (LHe)
Maximal thermal transfer < 1.5 watt
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.

Main function
The liquid He subsystem (SSHeL) of Ariane 5 and Ariane 6 launchers is designed to ensure the pressurisation of the liquid O2 tank of the cryotechnical main stage (EPC), propelled by Vulcain engine.
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.
