Vinci Purge Valve (PV)
A model, two functions
The Purge Valve (PV) is integrated into the Vinci engine of the Ariane 6 upper stage. This normally closed pneumatic poppet valve is designed to operate as 2 Hydrogen (HPV) and Oxygen (OPV) purge valves. Both are identical and installed on the line sections downstream of the 2 turbo pumps.
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.
