ABSTRACT:
A valve with a rotatable valving member has a vent hole extending between an internal cavity of the valve and another location to which excess pressure can be vented. The vent hole is sealed with a consumable vent hole seal device that ruptures or otherwise vents under the high temperature and/or pressure of a fire and prevents dangerous pressure buildup within the internal cavity of the valve.
