Abstract (en)
A method of controlling pressure in a pressure vessel provides a valving arrangement that isolates one of a pair of rupture disks while subjecting the other to pressure of the pressure vessel. In an over pressure situation, one of the rupture disks ruptures. A sensor then detects a lowering of pressure, signaling a controller to activate a valve actuator. The valving arrangement then switches positions of a valving member so that the other rupture disk is immediately available to protect an over pressure situation of the pressure vessel.
