ABSTRACT:
A thermally responsive pressure relief valve using a bimetallic valve disc as a component. The bimetallic valve disc is used as a temperature sensitive valve seal. When temperatures go beyond the set point of the disc, it opens the valve with a snap acting motion permitting pressure to be vented through the valve. The valve disc automatically resets and reseals the valve when temperatures return to the reset point of the disc.
