Rupture disc Y90 NS Nanoscored
Safety · Rupture Discs
Manufacturer: 
DonadonSDD Y90 reverse acting rupture discs are safety devices specifically designed to be set at very low burst pressure, to prevent sudden pressure variations from damaging industrial plants. Reverse acting rupture discs have a convex disc camber that remains unaltered under operating pressure until reverse pressure is reached and this can ensure long service life. DonadonSDD Y90 rupture discs uses advanced sector technology and provide reliable and precise protection in the most demanding applications, making DonadonSDD Y90 rupture discs the best choice for your plant’s safety.
