Parts Ordering
Each valve body-bonnet assembly is assigned a serial number, which can be found on the valve body. This same
number also appears on the actuator nameplate when the valve is shipped from the factory as part of a control valve
assembly. Refer to the serial number when contacting your Emerson Process Management sales office for technical
assistance. When ordering replacement parts, refer to the serial number and to the 11-character part number for each
part required 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 w arranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
