Parts Ordering

Each valve is assigned a serial number which can be found on the valve or on the nameplate (figure 2 and key 35, not
shown). The nameplate will normally be fitted to the actuator. Refer to this serial number when contacting your

Emerson sales office

or Local Business Partner 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 Automation Solutions 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.
