FC-RBV-31 High Performance Blast Valve
FC-RBV-31-D250 rapid blast valves are specifically developed for those applications where high air flow rate and blast protection from high peak pressure are required. It could stand the overpressure up to 20 bar reflected with long duration and shut off in milliseconds. It also could stand multiple blast impacts and maintains full functions after blasts. Its stream-line shape enable the high air flow efficiency.
FC-RBV-31-D250 rapid blast valves mainly serve civil defense, OGP, nuclear power plants, marine and chemical applications, etc.
Additional information
