Each valve is assigned a serial number which can be found on the valve or on the nameplate. The nameplate will
normally be fitted to the actuator. Refer to this serial number when contacting your Emerson Process Management
sales office for technical assistance. When ordering replacement parts refer to this serial number and give the part
description from the following parts list.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
