More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.
Valve 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.)
