FC-RBV-31(E) Exhaust blast valve is developed for working as passage of exhausted gas while providing blast protection. It can work under temperature range of -30 °C to +520 °C, stand the overpressure up to 20 bar reflected and shut off in milliseconds blocking 99% blast impulse. It also could stand multiple blast impacts and maintain full functions after blasts. Its stream-line shape enables the high air flow efficiency. FC-RBV-31(E) Exhaust blast valves mainly serve hardened shelters in civil defense and military.

| High performance of blast resistance | Being able to stand multiple blast impacts with peak pressure reflected up to more than 20 bar and maintain all functions after blasts. |
| High performance of protection | Being able to completely close in very short time to assure approximately 100% impulse block rate. |
| Heat-insulated setup | Being able to work as passage of exhausted gas while providing blast protection. |
| High ventilation volume | Ensuring the high air flow efficiency with the streamline design. |
| Automatic-reset | Being able to retrieve ventilation function automatically after the blast so as to minimize the maintenance. |
| Double acting | Providing protection from both positive pressure hit and sucking phase. |
