    The LO-V bi-directional Rupture Disc is designed to relieve undesired pressure conditions in two different directions

    Certain types of applications, such as storage tanks, need protection from vacuum pressure as well as from potential overpressure. The primary relief can be via the reverse-buckling section, which is typically extremely low vacuum pressure, or the higher pressure-activated, forward-acting section. Depending on how the holder is oriented, the LO-V can perform the tasks of two different rupture discs.

    NEGATIVE PRESSURE RELIEF

    In a typical storage tank application, when there is negative system pressure that is nearing the marked reverse-acting burst pressure of the disc, the buckle section begins to reverse, and the disc seal is contacted by the knife blades located in the holder inlet. This contact causes the seal to be penetrated at the touch point and a triangular pattern is cut to relieve the negative pressure. This buckle section controls the minimum to maximum vacuum relieving pressures. After reversing, the pre-punched holes in the perforated metal top section provide flow through the disc.

    POSITIVE PRESSURE RELIEF

    The perforated metal top features 6 holes at the apex of the rupture disc. These holes control the burst pressure in a forward-acting burst scenario. The rupture disc itself has six pre-cut sections that, in relieving positive overpressure, will open in a flower petal arrangement allowing quick relief. The LO-V is a non-fragmenting rupture disc and will withstand an 80% operating to stamped burst pressure ratio in the positive direction.
