Rupture Disc and Safety Valve

There are two different ways to combine rupture disc and safety valve. Rupture discs can be installed below the safety valve so that a perfect, leak-tight seal over a long period can be ensured. The second way is to install the two systems next to each other, the rupture disc ensures a backup system to release the pressure if the rise and pressure is to large and rapid that the safety valve cannot respond quickly enough or fails to open.
