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.
· High performance of blast resistance
Being able to stand multiple blast impacts with peak pressure reflected up more than 20 bar by long duration and maintain all functions after blasts.
· High performance of protection
Being able to completely close in very short time to assure approximate 100% impulse block rate.
· 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.
· High corrosion resistant performance
Being made of chemical-resistant materials and fit for all corrosive conditions.
