VALVES

We are engaged with the European Space Agency in a project for the development and qualification of an SMA-based valve for propulsion passivation of the fuel tanks in satellites at the end of life. It is designed to be compatible with all the typical chemical propellants and lighter than the pyrovalves.
Features
Development and qualification in the frame of an ESA contract of an SMA-based valve for propulsion passivation of the fuel tanks in satellites at the end of life. The valve is designed to be compatible with all the typical chemical propellants and to be lighter than the pyrovalves.
Low-shock, non-explosive

Redundant SMA trigger (two independent initiators)

Suitable for Propellants (N2H4, MON, MMH, LPM-103s), Inert gases (Kr, Xe, He, Ar) and all propellant vapors

Environmental operating temperature: -30 to +60C (gas application), 0 to +60C (liquid storable propellant application)

Environmental non-operating temperature: -50 to +90C (gas application), -2C to +90C (liquid storable propellant application)

Inlet operating pressure: MEOP = 310 bar

 External leak: < 1×10-6 scc/sec GHe at worst-case conditions (during min and max non-op temperature)

 Mass < Pyrovalve (410g not including harness).

 Lifetime on ground + on orbit = 25 years.

 Standard off-the-shelf and custom configurations available
