FSLPDFA - Forward Acting Rupture Discs
The FSLPDFA Forward Acting Rupture Discs provide a straightforward, dependable, precise, and cost-effective solution for applications that necessitate exceptionally low pressure protection, whether positive or negative. These rupture discs are primarily designed to safeguard processing and storage tanks, atmospheric vessels, and silos which have low design pressures, thereby offering resistance only to minor pressures and vacuums. A particularly noteworthy application is their role in protecting biogas digesters. FSLPDFA rupture discs are flat composite structures comprising four key components: a slotted, perforated metal section, a sealing membrane (typically manufactured from PTFE but available in various other metallic or non-metallic materials), a protective section, and a calibration ring with blades to enhance membrane rupture. FSLPDFA rupture discs operate without fragmentation, helping to prevent product contamination, and can be tailored to meet a wide array of non-standard specifications and applications. These discs can be engineered for dual pressure and vacuum protection, making them capable of withstanding vacuum or counter-pressure situations.
