The convex of reverse acting rupture disc is on the high pressure process side. When the solid metal disc is compression-loaded, the disk reverses with the knife blades on the upper holder cutting it to relieve pressure.
Note: Types and Specifications of Safety devices need to be calculated and selected according to the specific working conditions of the protected equipments and systems before quotations.
Technical features:
