Benefits

  • Perfect hermeticity of the valve as opposed to nonpyro valves (the mechanical barrier is ensured by the continuity of the material before getting breached by the cutter)
  • While and even after functioning the valve retains all gas generated from the pyrotechnic components and has no external outgazing
  • The functioning time of such equipment is extremely short

Applications

  • Fuel system of missile turbojet engines (cruise missiles, anti-ship missiles, etc.)
