Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use pressure-relieving devices as required by accepted industry, local, state, or Federal codes, and good engineering practices.
Check with your process or safety engineer for any other hazards that may be present from exposure to process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
The 1079 manual actuator is normally shipped mounted on the Hytork actuator. If the manual actuator is shipped separately for installation on the Hytork 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 Hytork actuator for use with the 1079 manual actuator requires fastening a mounting plate, included with the manual actuator, to the Hytork actuator. The 1079 actuator is installed between the valve and the Hytork actuator. Figure 2 shows the manual actuator standard and optional mounting positions. Typically the manual actuator is mounted with the input shaft perpendicular to the power actuator piston travel. However, the manual actuator can be mounted in any of four positions, provided there is sufficient clearance between the handwheel and the power actuator end caps. Fasten the mounting plate to the power actuator with the four mounting bolts provided withthemanualactuator.Donotexceedthetorquevaluesgivenintable5.

Installing the Manual Actuator
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
CAUTION
Undertravel or overtravel of the valve 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. Isolatethecontrolvalvefromthelinepressure,releasepressure 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. Make certain that the power actuator travel stops have been properly set.
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 in either the open or closed position.
4. Note whether the valve disk is in the open or closed position.
5. Engage the handwheel on the manual actuator. See the Engaging and Disengaging the Manual Actuator section in
this manual for instructions. Perform one or the other of the following procedures.
D If the valve disk is in the closed position: Rotate the handwheel clockwise until it stops.
D If the valve disk is in the open position: Rotate the handwheel counterclockwise until it stops.
6. Disengage the manual actuator.
7. Slide the manual actuator shaft into the power actuator.
8. 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.
9. Fasten the manual actuator to the power actuator with the bolts, lockwashers, and nuts provided.
10. Install the power actuator and manual actuator assembly on the valve as described in the installation section of
the power actuator instruction manual.

Operation
After the actuator and control valve assembly are 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 table 2, 3, or 4, refer to the maintenance procedures.
Engaging and Disengaging the Manual Actuator
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
Engaging the Manual Actuator
1. Shut off 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.
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, approximate system balance should be achieved. Take appropriate steps to ensure that the return to automatic operation will not result in a extreme repositioning of control valve components.
1. Before disengaging the manual actuator, approximate system balance should be achieved. The system is in balance
when the actual valve 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 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 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 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.
5. Close the bypass valve 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.
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, 3, or 4, 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 disk 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 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.
