Installation

The 1080 manual actuator is normally shipped mounted between the valve assembly and the FieldQ actuator. If the
manual actuator is shipped separately for installation on the FieldQ actuator, or if the manual actuator was removed
for maintenance, mount the manual actuator by following the instructions in this section.

Field conversion of the FieldQ actuator for use with the 1080 manual actuator requires fastening an adaptor plate,
included with the manual actuator, to the FieldQ actuator. The 1080 actuator is installed between the valve and the
FieldQ actuator.

Figure 2 shows the manual actuator mounting positions. Positions 1 and 3 are possible with all sizes of the FieldQ.
Positions 2 and 4 are only possible for FieldQ sizes Q40 through Q350 and Q1600. Fasten the adaptor plate to the
power actuator with the mounting bolts provided with the manual actuator. Use the torque values given in table 3.

Installing the Manual Actuator

If you purchased the 1080 actuator as part of a valve and power actuator assembly, step 13 is the only step you will
need to perform in the following procedures. If you purchased the 1080 actuator separately, perform all the steps and
read all warnings and cautions below.

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the
process media from both sides of the valve. Also shut off all pressure lines to the power actuator and release all
pressure from the power actuator. Use lock‐out procedures to be sure that the above measures stay in effect while
you work on the equipment.

2. For spring‐return power actuators, allow the power actuator to remain in the position where the spring is relaxed.
For double‐acting power actuators, apply supply pressure as appropriate to position the valve disc in either the
open or closed position.

3. Note whether the valve disc is in the open or closed position.

4. Engage the handwheel on the manual actuator. See the Engaging and Disengaging the Manual Actuator section in
this manual for instructions.

5. If using position 1 or 3 from figure 2, rotate the handwheel to line up the index mark on the top of the manual
actuator shaft and the drive shaft on the top of the power actuator. If using position 2 or 4 from figure 2, the index
mark on top of the power actuator input drive on the 1080 must be perpendicular to the face of the valve disc and
the slot in the top of the power actuator shaft (see figure 3).

6. Determine the correct relative positions of the power and manual actuators (see figure 2).

7. Remove the adaptor plate on the top of the gear box (see figure 3).

8. Attach the adaptor plate to the bottom of the power actuator with bolts furnished with the adaptor plate.

9. Slide the power actuator input drive into the power actuator (see figure 3).

10. Rotate either the manual actuator or the power actuator slightly so that the mounting holes on the manual
actuator align with the mounting holes in the mounting plate on the power actuator.

11. Fasten the manual actuator to the mounting plate with the bolts, washers and nuts provided (see table 3).

12. Install the power actuator and manual actuator assembly on the valve as described in the installation section of
the power actuator instruction manual. Remember the positions noted in steps 3 and 6, because you will need
them when aligning the drive shaft on the top of the power actuator and the valve shaft.

CAUTION

Undertravel or overtravel of the valve disc, especially at the closed position, may result in poor valve performance and/or
damage to the equipment. Make certain that the power actuator travel stops are properly set before installing the valve.
Refer to the instruction manuals for the power actuator for information about setting travel stops.

13. Make certain that the power actuator travel stops have been properly set. FieldQ actuator travel stops, the travel

stop adjustments are made in the power actuator. The adjusting travel stops procedure is in the FieldQ Instruction

Manual.

14. Install the valve in the line using the instructions in the valve instruction manual.

Operation

After the actuator and control valve assembly are installed, the manual actuator is ready for operation.

WARNING

Applying too much torque to the actuator and valve parts could cause damage to the parts and result in loss of control of
key internal valve components (e.g. disc or ball). This loss of control may result in personal injury due to a sudden increase
or decrease of pressure within
exceed the wheel rim force listed in table 2. Also, do not use wrenches or other devices on the handwheel or handwheel
shaft to increase operating force.

If the force required to rotate the handwheel exceeds the wheel‐rim force listed in table 2, refer to the Maintenance
procedures.

Engaging and Disengaging the Manual Actuator

Engaging the Manual Actuator

1. Engage the manual actuator before venting the power actuator loading pressure. Releasing the air pressure prior to
engaging could result in undesirable valve rotation.

WARNING

Undesirable valve rotation or loss of control of key internal valve components (e.g. disc/ball), may result in personal injury
due to a sudden increase or decrease of pressure within

2. Pull the ring on the detent mechanism to unlock the lever. At the same time, move the lever into the engaged
position until it is against the stop pin and locked in position by the detent mechanism. See figure 3.

3. If the lever sticks midway, turn the handwheel 1/3 turn (2 full turns for units with additional gearbox between the
handwheel and lever). Then try the detent lever again. Repeat this step as necessary, turning the handwheel in the
same direction, until the lever moves freely (see figure 4). The reason the lever may stick is that the worm is not in
proper alignment with the gear (see figure 4). Rotation of the worm will allow for proper alignment. Excessive force
should not be required.

4. Shut off supply pressure to the power actuator and bleed off or equalize pressure in the cylinders. If applicable,
open the power actuator bypass valve.

‐ or release of pressure from ‐ the pipeline.

Note

If the loading pressure in the power actuator has already been released, you will not need to use the optional bypass relief valve.

Disengaging the Manual Actuator

WARNING

Disengaging the manual actuator when forces, such as spring compression, cylinder pressure, and dynamic torque, are
present may cause sudden, extreme movement of all control valve components. Disengaging the lever with excessive force
can result in damage to equipment and violent disturbance of the process.

Damage to equipment resulting in loss of control of internal valve components (e.g. disc/ball) ‐ or violent disturbance of
the process may result in personal injury due to a sudden increase or decrease of pressure within
from

‐ the pipeline.

Before disengaging the manual actuator, take appropriate steps to ensure that the return to automatic operation will not
result in an extreme repositioning of control valve components. Procedures to determine approximate system balance are
given in the following steps.

1. Approximate system balance should be achieved, before disengaging the manual actuator. The system is in balance
when the actual valve disc position is approximately the same as the position requested by the automatic control
system. Under balanced system conditions, the manual actuator disengaging lever moves freely without use of
excessive force.

‐ or release of pressure

If after releasing the detent mechanism, the lever does not move freely toward the disengaged position, some system
force is causing an imbalance. A forced return to automatic operation under these conditions can cause serious
damage to the equipment and violent disturbance of the process.

2. If possible, determine whether the automatic control system is tending to open or close the valve disc, and rotate
the handwheel in the appropriate direction until the lever can be easily moved by hand. As an alternate approach,
local manipulation of the supply pressure to the power actuator may bring the set point of the automatic system
closer to the actual valve disc position.

3. If a smooth transition from manual to automatic operation cannot be ensured, isolate the valve from the process.
On Spring Return actuators, position the manual actuator and the disc to the spring fail open or close (whichever is
applicable) end of travel so that no position changes will happen when supply pressure is applied to the power
actuator. On double‐acting actuators, this positioning will not be necessary.

4. Pull the ring on the detent mechanism to unlock the lever. Push the lever into the disengaged position until it is
against the stop pin and locked in position by the detent mechanism.

5. Close the bypass valve, if needed, and return supply pressure to the power actuator.

Maintenance

WARNING

Avoid personal injury from sudden release of process pressure or bursting of parts. Before performing any maintenance
operations:

D Do not remove the actuator from the valve while the valve is still pressurized.

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the power actuator. Be sure

the actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve. Drain the process media from both sides of the valve.

D Vent the power actuator loading pressure and relieve any actuator spring precompression. If using a Spring Return

actuator, first check to make sure the valve has been moved to the fail safe position to prevent unexpected actuator
movement.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

If the force required to rotate the handwheel exceeds the wheel‐rim force listed in table 2 check for the following
conditions:

D Insufficient lubrication

D Seized actuator parts

D Excessive pressure drop across the valve, or

D Obstruction to the valve disc rotation.

If the manual actuator does not seem to control the process fluid, the worm or drive sleeve gear teeth may be broken,
the handwheel pin may be sheared, or the power actuator or internal valve parts may be broken.

Instruction Manual

D500236X012

Refer to the power actuator and valve instruction manuals if power actuator or valve maintenance is needed.

Lubrication

The interior parts of the 1080 manual actuator should be lubricated on a regular schedule with a quality gear lubricant.
The interior parts should also be lubricated whenever difficulty in handwheel rotation indicates a need for lubrication.

WARNING

Before performing any of these lubrication procedures, observe the steps in the WARNING at the beginning of the
Maintenance section.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the
process media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power
actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in
effect while you work on the equipment.

2. Remove the bolts that secure the power actuator to the manual actuator adaptor plate and remove the power
actuator.

3. Remove the cap screws that secure the gearbox lid and remove the gearbox lid.

4. Coat the worm, the drive sleeve gear teeth, and the bearing surfaces of the gearbox housing and worm with a
quality gear lubricant.

5. Replace the cover plate and cap screws using the bolt torques listed in table 5.

6. Replace the power actuator on the manual actuator. Fasten the manual actuator to the adaptor plate using the
torque values in table 3.
