Abstract

Una valvola di scarico di sicurezza avente un organo portante un disco con una flangia che si estende in basso che si sovrappone ad un anello di regolazione ubicato su di un organo a sede di valvola per fornire una alzata nominale completa più rapida ed uno scarico più breve. La flangia che si estende in basso ha una estremità smussata per formare un orifizio fra la superficie periferica esterna dell'organo ad anello di regolazione per mezzi che fluiscono.
