ABSTRACT:
An alarm system for a particular type of lifting seal type valve, such as those employed in pressure relief. The alarm system consists of a signal source, an alarm mechanism and a signal carrying conductor secured to a seated lifting seal valve in such a manner that valve actuation will disrupt the transmission, interrupting the signal and activating the alarm.
