AMV-EVN-24-01 Miniature Valves in Space Use – PERSIS Project
Application: Additive Manufacturing of Structural Components in Space
Product Used: AMV-EVN-24-01 Axial Miniature Valve
Client: PERSIS – an interdisciplinary student project at the Munich University of Applied Sciences and the Technical University of Munich
Initial Situation: The PERSIS team developed an experiment for use on board a sounding rocket as part of the REXUS/BEXUS program. The goal of the project was to manufacture carbon fiber-reinforced structural components under space conditions.
For this purpose, a photopolymer resin was to be precisely dosed and cured under UV light – an innovative step towards additive manufacturing in space. Compact, reliable miniature valves were required to precisely control the resin flow and operate reliably even under extreme conditions.
The Solution
After an intensive technical discussion, the PERSIS team chose our AMV-EVN-24-01 miniature valves. These valves impressed with:
- their compact design,
- their low weight,
- low power consumption,
- and the reliable 2/2-way switching mechanism.
During the preparations, we supported the team with several valves. To cope with the thermal stresses during rocket flight, the team constructed special housings for heat dissipation – visible in project photos.
The Result
The rocket launch took place on March 11, 2025 – with complete success:
The experiment worked as planned. Four of our AMV-EVN-24-01 valves were used on board – they opened and closed as intended, enabling successful resin flow for component manufacturing.
The PERSIS team's conclusion:
"Your valves worked great! We had four valves on board, and all of them opened and closed as planned."
