FSDIFULP - Ultra Low Pressure Rupture Discs

FSDIFULP - Ultra Low Pressure Rupture Discs

The FSDIFULP Ultra Low Pressure Rupture Discs are composite conventional discs formed by four parts: a slotted, perforated metal part a seal membrane (usually in PTFE but also available in many other metallic or non-metallic materials) a protection section a calibration ring This disc has been designed to be mounted between flanges. It is excellent for use with gas and liquids in static conditions and excellent for low pressures. FSDIFULP discs react to excessive pressure with total opening in a few milliseconds. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection. Composite rupture discs may also be used for simultaneous protection from pressure and vacuum.
