Valves at a glance
Benefits of pyrotechnics
-
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
Defence applications
-
Fuel system of missile turbojet engines (cruise missiles, anti-ship missiles, etc.)
