The convex of reverse acting rupture disc is on the high pressure process side. When the metal disc is compression-loaded, the disk reverses with a crocodile tooth diaphragm cutting it to relieve pressure.
Options
Fluoroplastic lining or coating.
BI burst indicator sensor
*Note: Temperature resistance of lining and BI is lower than the strength membrane
Suitable for safety valve isolation/
When installed beneath a safety valve, the rupture disc isolates the valve's working components from corrosive media.
Venting assembly components: pressure gauge, tee fitting, relief valve, and adapter nipple
