Rupture Pin Valves, also known as rupture discs or burst discs, are pressure relief devices designed to protect equipment and systems from overpressure conditions. These valves consist of a thin, usually metallic, disc or membrane that is engineered to rupture at a predetermined pressure. When the pressure in the system exceeds this threshold, the rupture pin valve opens, releasing the excess pressure and preventing potential damage to the equipment.

Unlike traditional relief valves, rupture pin valves offer a fast and reliable response to overpressure events. The simplicity of their design, comprising a metal disc held in place by a holder or retainer, allows for precise pressure control and quick activation. Rupture pin valves find applications in various industries, including oil and gas, chemical processing, pharmaceuticals, and manufacturing, where safeguarding against pressure buildup is critical for maintaining the integrity of processes and ensuring the safety of personnel and equipment.
