The FSLPDDW Double Way Rupture Discs are sophisticated composite conventional discs constructed from four key components: a slotted, perforated metal section, a sealing membrane (typically made from PTFE, but also available in various metallic and non-metallic materials), a protective section, and a calibration ring. Designed to be installed between flanges, these discs are ideal for use with gases and liquids in static conditions, particularly at low pressures. The FSDIFDW discs promptly react to excessive pressure, achieving complete opening within milliseconds, making them an excellent choice for valve protection. Vacuum or counter-pressure support options are also available. Additionally, composite rupture discs offer simultaneous protection from both pressure and vacuum.
