The cabin crew was briefed on the situation and an emergency descent was initiated when the cabin altitude reached 9500 feet; a PAN PAN was then declared. Approaching FL190, the cabin altitude stabilized and began to recover after reaching a maximum of 10 500 feet. The flight crew stopped the descent at FL190, assessed the situation and decided to initiate a climb to FL250 in order to determine if the cabin altitude would remain stable, which it subsequently did. The cabin oxygen masks did not deploy during the occurrence. The flight continued to destination without further incident and there were no injuries. The operator?s maintenance inspected the aircraft and identified the ENG 1 PRV valve to be defective. The unit was removed and replaced. Subsequent tests were completed successfully and the aircraft was returned to service. The operator captured the occurrence in their SMS for future trend analysis and monitoring.
