Description

The 1078 manual actuator, shown in figures 1 and 2, is a declutchable unit for manual operation of control valves and

equipment that use power actuators. The 1078 manual actuator mounts directly to Fisher 1052 size 70; 1061 sizes 30,

40, 60, 68, 80, and 100; and to all sizes of 2052 actuators. The 1078 manual actuator can be engaged to allow manual

operation of the valve when the power actuator is not in use. It can be disengaged to allow automatic operation of the

valve by the power actuator. The mechanism used allows manual actuator engagement at any point of power actuator

rotation.

Installation

WARNING

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.

Instruction Manual

D101329X012

1078 Actuator

June 2017

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this

instruction manual.

The 1078 manual actuator is normally shipped mounted on a power actuator. If the manual actuator has been shipped

separately for installation on a power actuator, or if the manual actuator was removed for maintenance, mount the

manual actuator by following the instructions presented in this section.

Converting An Existing Power Actuator For Use With The Fisher 1078

Manual Actuator

Field conversion of a power actuator for use with the 1078 manual actuator may require replacement and/or removal

of some parts. The procedures which follow apply only to power actuators which were not ordered specifically for use

with the 1078 manual actuator. Proceed as appropriate:

Installing the Manual Actuator

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

on 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.

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.

CAUTION

Undertravel or overtravel of the valve ball or disk, 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 and

adjusting the manual actuator. Refer to the instruction manuals for the valve and the power actuator for information about

setting travel stops.

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

Instruction Manual

D101329X012

1078 Actuator

June 2017

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. Make certain that the power actuator travel stops have been properly set according to the caution given above.

3. 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 disk or ball in either

the open or closed position.

4. Note whether the valve disk or ball is in the open or closed position.

5. Rotate the handwheel to move the drive sleeve gear and travel indicator to the position that corresponds with the

position of the valve disk or ball. For both direct and reverse acting manual actuators, clockwise handwheel rotation

sets the manual actuator to the closed position. Counterclockwise handwheel rotation sets the manual actuator to

the open position.

Installing the Manual Actuator on a 1061 Size 30, 40, 60, 68, 80, or 100 and 1052 Size 70

For manual actuator installation on 1061 sizes 30, 40, 60, 68, 80, and 100; and 1052 size 70, remove the actuator

cover (key 34) and attached parts from 1061 or 1052. Replace with 1078. Most assemblies require installation of a new

lever and splined adaptor to complete the installation. When used, the splined adaptor slides inside the new lever and

the lever is then clamped onto the splined adaptor. See figure 5.

1. Remove the lever and add a new lever and splined adaptor when needed. See figure 5.

The splined adaptor slides inside the new lever and the lever is then clamped onto the splined adaptor.

2. Disengage the manual actuator.

3. Install the manual actuator.

4. Tighten the cap screws to the final torque value.

5. For double‐acting power actuators, be certain the power actuator is equipped with a bypass valve. Operating the

handwheel mechanism against the force of differential cylinder pressures will be difficult or impossible.

Installing the Manual Actuator on a 2052 Size 1, 2, or 3

1. Remove the travel scale and travel indicator. They will no longer be required since the 1078 has it's own scale and

indicator.

2. Mount the manual actuator on the surface where the travel scale was.

3. Position the manual actuator on the 2052 so that the drive square fits into the quad square spline of the 2052 lever.

4. Bolt the manual actuator onto the 2052.

Operation

After the travel indicator pointer has been adjusted and the control valve assembly installed, the manual actuator is

ready for operation.

CAUTION

Applying too much torque to the actuator and valve parts could cause damage to the parts. To avoid such damage, do not

exceed the maximum allowable torques listed in table 2, 3, or 4 or any other torque limitation of internal valve parts. 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 tables 2, 3, and 4, refer to the

maintenance procedure.

Instruction Manual

D101329X012

1078 Actuator

June 2017

Engaging and Disengaging the Manual Actuator

Engaging the Manual Actuator

1. Shut off the supply pressure to the power actuator.

2. Pull the ring on the detent mechanism to unlock the lever. Move the lever into the engaged position until it is

against the stop pin and locked in position by the detent mechanism. (Note that stop pins are not available on 1078

size II‐FA actuators.)

3. If applicable, open the power actuator bypass valve.

Disengaging the Manual Actuator

CAUTION

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. This can result in damage to equipment

and violent disturbance of the process. 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. Before disengaging the manual actuator, approximate system balance should be achieved. The system is in balance

when the actual valve ball or disk 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. 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 ball or disk, and

rotate the handwheel in the appropriate direction until friction in the manual operator is reduced and 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 ball or disk position.

3. If a smooth transition from manual to automatic operation cannot be ensured, isolate the valve from the process.

Position the manual actuator so that it matches the position of the ball or disk when no supply pressure is applied to

the power actuator.

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. (Note that stop pins are not available on 1078

size II‐FA actuators.)

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

Maintenance

If the force required to rotate the handwheel exceeds the wheel‐rim force listed in tables 2, 3, and 4, check for the

following conditions:

D Insufficient lubrication,

D Seized actuator parts,

Instruction Manual

D101329X012

1078 Actuator

June 2017

D Excessive pressure drop across the valve body, or

D Obstruction to the valve disk or ball rotation.

If the manual actuator does not seem to control the process fluid, the worm or drive sleeve gear teeth may be broken,

the pin (key 3) may be sheared, or the internal power actuator or valve parts may be broken. Purchase a replacement

manual actuator if necessary. Refer to the power actuator and valve instruction manuals if power actuator or valve

maintenance is needed.

Lubrication

The interior parts of the 1078 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

Avoid personal injury from sudden release of process pressure or uncontrolled movement 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.

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.

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. Mark the position of the travel indicator pointer on the indicator dial. The travel indicator pointer must be returned

to its original position when assembling the manual actuator. Remove the machine screws and the travel indicator

pointer.

3. Remove the manual actuator cover screws.

4. Remove the travel indicator scale and the gearbox cover plate. Coat the worm, the drive sleeve gear teeth, and the

bearing surfaces of the gearbox housing and worm with a quality gear lubricant.

5. Install the cover plate and the travel indicator scale on the gearbox.

6. Replace the manual actuator cover screws.
