FM Approvals has been made aware that Neles USA Inc received a report of an incident during a demonstration test of their FM Approved Figure 1075 fire safe safety shutoff valves where a fusible link melted and the spring handle did not fully release to close the valve. Metso subsequently evaluated the release mechanism in their lab and determined it did not consistently release the handle to close the valve. The method of attaching the fusible link to the valve actuator has since been modified to provide consistent valve closure and was successfully tested by FM Approvals.
