Tank-Safe is designed for use on intermodel tank containers to meet the requirements of the various international standards relating to transportation of dangerous goods.

The disc is of composite construction and does not require a holder. It is mounted directly below the relief valve. The construction comprises of three main components, a slotted top section, seal membrane and vacuum support. At the set pressure the disc bursts and petals open to give full bore relief.
