The BURST DISK is a safety device that can be mounted on the gas side of the bladder and piston accumulators.
Its function is to protect the accumulator from any excessive pressure that may exceed the maximum design limit of the accumulator itself causing damages to equipment and people.
The rupture of the disk is a drastic measure; in fact you will assist to the full release of all the contents of the accumulator (nitrogen).
Reaction to end of overpressure: it does not close, and then the disk must be replaced.
The burst disk is composed of a properly drilled hexagonal cap in stainless steel AISI 316L on which it is brazed a calibrated and concave membrane, which will explode at the pre-set value. It can be installed in any position
