V260 Valve
24. Lift the second tailpiece assembly and align it
with the valve body studs and pins. Slide the
tailpiece onto the studs and bearing plate pins. The
groove pins in the valve body should be guided into
the pin holes in the tailpiece. Pull it up tightly, taking
care not to damage the tailpiece O-ring as it is pulled
into the valve body.
25. Install the hex nuts (key 19) on the studs (key 3)
and hand-tighten them. Torque all the hex nuts
evenly.
WARNING
Refer to table 3 for bolt torque
requirements. Exceeding any torque
requirements could damage the valve
and impair safe operation.
26. Refer to the Packing Maintenance section to
install the packing parts.
Actuator Mounting
Use the appropriate actuator instruction manual
when mounting the actuator or changing actuator
styles and positions.
Determining Mounting Position
The actuator can be either right- or left-hand
mounted.
D Right-hand mounting means that
the actuator is mounted on the right
side of the valve when viewed from the
valve inlet.
D Left-hand mounting means that
the actuator is mounted on the left
side of the valve when viewed from the
valve inlet.
Right- or left-hand mounting can change the actuator
action from push-down-to-close to
push-down-to-open, or vice-versa.

Note
Determining Closed Position
1. You must remove the valve from the pipeline to
check the position of the ball.
2. Adjust the actuator linkage or travel stops as
described in the actuator instruction manual. Adjust
the actuator so that the valve ball will be fully open
or closed when the actuator is at the end of its
stroke, depending on the actuator action selected.
Parts Ordering
A serial number is assigned to each valve and
stamped on the nameplate. Always refer to the valve
serial number when corresponding with your
Emerson Process Management sales office
regarding spare parts or technical information. When
ordering replacement parts, also specify the part
name and desired material.
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.
Neither Emerson, Emerson Process
Management, nor any of their affiliated
entities assumes responsibility for the
selection, use, or maintenance of any
product. Responsibility for the
selection, use, and maintenance of any
product remains with the purchaser
and end user.
