FC-RBV-31(E) High Performance Exhaust Blast Valves
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.
