Pressure Burst Discs have been developed as a safety device to protect vacuum systems against back fill over-pressure. They can be used on any type of system where over-pressurization is undesirable. When over-pressure occurs, the thin diaphragm comes in contact with the sharp edges of the housing and ruptures, relieving the pressure in the system. Once ruptured, the unit must be discarded and replaced. The disc is designed to burst at a positive pressure anywhere in the range from over atmosphere to 25 psig, with rupture certain to occur before 25 psig.
