The DONADON GM of monoblock graphite rupture disc is versatile and suitable for numerous applications. It may be directly inserted between flanges
Graphite discs are very resistant to aggressive fluids, even at high temperature.
Bursting pressure has low sensitivity to temperature variations.
GR disc is made of high purity graphite impregnated with phenolic resins in order to make the product non porous
Opening is total but with fragmentation.
Vacuum support is required for rupture pressures below 1.7 Bar. At higher calibrations the disc is self-supporting.
