PART 21 NOTIFICATION - LOOSE BUTTERFLY VALVE TAPER PINS
Fisher Controls issued FIN 2019-01 for all Fisher type 7600, 7700, 7800, 9100, 9200, and 9500 series butterfly valves that use taper pins to secure the valve shaft to the valve disk. This does not apply to valve constructions that use straight pins or grooved straight pins. Fisher was notified on June 25, 2019 of one instance where a taper pin became loose due to incorrect installation within the valve.
Fisher recommends the owners of these valve assemblies perform normal maintenance at regular intervals in order to inspect the valve assembly and replace worn, aged, and damaged parts, as well as verifying that the taper pins are correctly installed and reset them if necessary.
