Scope of Manual
This instruction manual includes installation, adjustment, maintenance, and parts ordering information for the Fisher
1069 dual piston pneumatic rotary actuator (see figure 1). Instructions for the control valve body, the valve positioner,
and accessories are included in separate instruction manuals.
Description
The 1069 dual piston pneumatic rotary actuator is for use with larger sizes of rotary shaft valves such as NPS 16
through 24 V250 ball valves and NPS 30 and 36 8510 eccentric disk valves. The 1069 actuator can be used for
throttling service when equipped with a valve positioner, or for on‐off service when equipped with switching devices.

Do not install, operate, or maintain a 1069 actuator without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson sales office or Local Business Partner before
proceeding.
Specifications
Specifications for 1069 actuators are shown in table 1. Specifications for a given actuator, and manual operator if used,
as it originally comes from the factory, are stamped on a nameplate (key 32, figure 4) attached to the actuator.
Installation
When an actuator and valve body are shipped together, the actuator is normally mounted on the valve body. Follow
the valve body instructions when installing the control valve in the pipeline. If it is necessary to mount the actuator on

the valve body, or if it is necessary to change actuator mounting positions, perform the actuator mounting
procedures.
WARNING
To avoid personal injury or property damage caused by bursting of pressure‐retaining parts, be certain the cylinder
pressure does not exceed the cylinder pressure limits listed in table 1. Use pressure‐limiting or pressure‐relieving devices to
prevent the cylinder pressure from exceeding these limits.
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
Actuator Mounting
Use the following steps to connect a valve body and actuator that have been ordered separately. This procedure can
also be performed to change actuator mounting positions. Key numbers used in this procedure are shown in figure 4.
CAUTION
To avoid possible damage to the travel stop screws (key 35 and, if used, key 9), make sure the travel stop screws are turned
all the way into the housing (key 15) before setting the housing on its support legs.
1. Remove the cap screws and washers (keys 25 and 38) and then remove the cover (key 24). If a manual operator is
used, it is removed with the cover.
2. Remove the cap screws and anti‐rotator assemblies (keys 8 and 42).
3. If the lever (key 19) is attached to the valve shaft, loosen the cap screws (key 20) and rotate the set screw (key 41)
clockwise slightly to spread the split portion of the lever. Then, remove the lever through the openings in the
housing (key 15). For an 8510 valve body, the disk must be open approximately 20 degrees to allow enough
clearance for lever removal. For a V250 valve body, the ball must be open approximately 70 degrees to allow
enough clearance for lever removal. Consult the valve body instruction manual for assistance during this step.
CAUTION
Do not use a hammer or similar tool to drive the lever (key 19) off the valve shaft. Driving the lever could damage internal
valve parts. On some valve bodies, driving the lever could move the valve disk and bearings away from the centered
position, causing subsequent damage to valve parts as the valve is operated.
If necessary, use a wheel puller to remove the lever. It is okay to tap the wheel puller screw lightly to loosen the lever, but
hitting the screw with excessive force could also damage valve parts or disrupt the centered position of the valve disk and
bearings.
4. If the housing was removed from the mounting yoke (key 17), secure it to the mounting yoke with the cap screws
(key 18).
5. Consult figure 2 for available mounting positions. The actuator is normally positioned vertically with the valve body
in a horizontal pipeline. If changing actuator mounting positions, unscrew the cap screws (key 18) and rotate the
housing (key 15) to the desired position.

6. If the actuator and valve body are separated, mount the actuator on the valve body with the valve body cap screws.
When mounting the actuator, make sure that the bearing (key 40) and valve shaft are in line so that the bearing will
slide onto the valve shaft without being damaged. Refer to the appropriate valve body instruction manual for
bolting torques for the cap screws.
CAUTION
Refer to table 2 for actuator bolt torque requirements. Exceeding any torque requirement could damage actuator parts and
impair safe operation.
7. To aid installation of the lever, apply lithium grease (key 45) to the exposed valve shaft spline. It may be necessary
to rotate the set screw (key 41) clockwise slightly to spread the split portion of the lever and allow installation onto
the valve shaft.
8. Consult the appropriate valve body instruction manual for lever/valve shaft orientation marks and slide the lever
into place. Consult figure 3 for the appropriate lever operating clearances. When the lever is in place, back off the
set screw (key 41) so that the lever can be clamped onto the valve shaft. Secure the assembly with the cap screws
(key 20).
9. Rotate the lever until both cap screw holes are aligned with both rod end bearings (key 7).
10. Connect the lever to each rod end bearing with a cap screw and anti‐rotater assembly (keys 8 and 42). Cap screw
torques are listed in table 2.
