Angular seat rupture disc DCD

titanium

DonadonSDD DCD rupture discs are composite conventional discs formed by three 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 It is excellent for use with gas and liquids in static conditions and excellent for low pressures. DCD discs react to excessive pressure with total opening in a few milliseconds without fragmentation. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection. Composite DonadonSDD rupture discs may also be used for simultaneous protection from pressure and vacuum. Tolerance - from +/- 5 % to +/- 20% Operating temperature - membrane in PTFE/PFA max 265°C, up to 480°C (depending on the membrane) Operating margin - up to 80% Vacuum support - Available Fragmentation - No (membrane only) Use under valve - Yes Corrosion resistance - Good - can be protected with a PTFE membrane Linings - Yes Container - HI/A, HI/P, HI/F, HTC Rupture sensor - Electrical, Magnetic, Inductive, Optical PED Certification [CE STAMP] - Available ATEX EX II 2 GD Certification - Available
