CV500 Valve
Instruction Manual
Form 5302

Changing Actuator Mounting Style
Refer to figure 3 of this manual and the actuator
instruction manual when changing mounting styles
or positions. Right-hand mounting places the
actuator on the right side of the valve as viewed from
the upstream side of the valve; left-hand mounting
places the actuator on the left side of the valve.
Remember that the upstream side of the valve inlet
is the retainer end of the valve body for forward flow
and the other end of the valve body is the upstream
side for reverse flow.
Complete the Adjusting Actuator Travel procedure in
this manual whenever the actuator is removed.
Parts Ordering
A serial number is assigned to each valve body and
stamped on the nameplate. Always refer to this
serial number when corresponding with your
Emerson Process Management sales office
regarding spare parts or technical information. When
ordering replacement parts, also specify the
complete 11-character part number from the Parts
List.
Note
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 will void your
warranty, might adversely affect the
performance of the valve, and might
jeopardize worker and workplace
safety.
Note
Neither Emerson, Emerson Process
Management, Fisher, nor any of their
affiliated entities assumes
responsibility for the selection, use
and maintenance of any product.
Responsibility for the selection, use,
and maintenance of any product
remains with the purchaser and
end-user.
