Bursting disc for sterile installations

Accueil » Protection against pressure and vacuum » Page 6

Applications :

Disc for liquids, gas and vapors

Construction in accordance with directive 97/23/CE :

Between 2 laser-cut metal foils lies a PTFE sealing membrane
EPDM (FDA) or PTFE gaskets
Non fragmenting disc
Vacuum resistant
DN20 to DN50

Materials : Stainless steel 316, Nickel, Hastelloy®, Inconel

Alternatives :

Reverse buckling discs: full metal discs
Bi-directional
Seamless surface design for sterile applications Ra< 0,8µm
PTFE lining on process side

Some other type of bursting discs (stainless steel, nickel, inconel, graphite…) may reach your need, feel free to contact us.

Composite_Clamp_1 — Disc for sterile installations

1. Mounting directly between clamp ferrules :

Clamps according to ISO / DIN 32676 / Inches

2. Mounting with inductive detector in a longer upper clamp :

Inductive detector mounted in a longer upper clamp
Detection plate welded on the disc, fixed in front of the detector

Alarm system for graphite safety disk

Accueil » Protection against pressure and vacuum » Page 6

Detecteur_ouverture_1 — Detection with Two tantalum contacts

Detecteur_ouverture_2 — Detection with contact finger

Description :

The alarm systems used for monitoring graphite safety discs provide a visual and acoustic alarm or trigger plant cutoffs. Two tantalum contacts or a contact finger in the alarm system press against the membrane of the safety disc and close the circuit of an amplifier relay. When the safety disc ruptures, the current circuit is interrupted and this triggers the alarm.

Advantages :

Corrosion resistance ensured by use of suitable materials
Reusability after safety disk rupture
Simple electrical connection via the 1.5 meter-long integral connecting cable
Used together with the matching amplifier relay, this system can also be operated in high explosion risk zones

Technical data :

Service voltage : AC 207V-253V, 45Hz – 60Hz, DC20 V – 30V
Circuit [EExia] II C, input as per DIN 19234 (Namur)
Output: 1 changeover AC 253 V / 2 A, DC 40 V / 2 A
The amplifier relay should be mounted outside the explosion risk zone
