DonadonSDD STD rupture discs are conventional concave solid discs.
This is a simple and reliable system used with gas and liquids in cyclic and pulsating pressure conditions. SCS discs react to excessive pressure in a few milliseconds. Supports may be provided for vacuum or counter-pressure protection.
