1. General
1.1 Introduction to Actuator
A) The Honeywell pneumatic cylinder actuator has been designed to meet the requirements of valve
operation.
B) The Honeywell pneumatic cylinder actuator has been designed for easy maintenance.
C) The Honeywell pneumatic cylinder actuator boasts a long life span and has few faults. To use the
product to its full life span, you should install it correctly according to the manual and maintain it
according to the prescribed procedures while using it.
♣RECOMMENDATIONS
Engineers who have professional assembly capabilities are required to maintain Cylinder Actuator.
Therefore, it is more economical to request repairs of the valves to Honeywell. As the valves repaired
by Honeywell are thoroughly tested and warranted, you are recommended to entrust Honeywell with
repairs.
1.2 Actuator Structure
A) The Honeywell pneumatic cylinder actuator is Canted Scotch Yoke type. (See Fig 1)
Fig1ScotchYokeType
To avoid possible injury to personnel or damage to valve parts, WARNING
and CAUTION notes must be strictly followed. Modifying this product,
substituting non-factory parts or using maintenance procedures other than
outlined could drastically affect performance, be hazardous to personnel and
equipment and may void existing warranties.

2. Storage
A) Do not throw, drop or drag the actuator when transporting it.
B) Keep all parts of the actuator in a well-ventilated place protected from fire, rain and wind.
Store the valve at a temperature between - 29℃(-20℉) and 48℃(120℉).
The storage area must be protected from flooding.
C) Operate the elastomer (O-ring type) of air pressure-type actuator at least once every six months to
prevent their functional degeneration. Operate it to the full stroke even under general operation
conditions at least three times a month.
♣Valve Handling Method (During Transportation)
- WARNING -
Do not hold it up or drag it using the stopper part when moving it.
(The stopper part may leak by air pressure.)

3. Operation
3.1 Inspections before Operation
A) Check whether there is any leak from all connections including the air pipe connections.
B) Check whether the attached manual hand wheel is at the Neutral position.
C) Check whether the air pressure required for valve operation is accurately set.
(Cylinder Actuator: 5.0 kgf/cm2, Special specification: 6.0 kgf/cm2)
- WARINING -
①Remove air pressure from the actuator before using the manual hand wheel. If you use
the hand wheel without removing air pressure, it may not work normally and its weak
part may get damaged by overstrain.
②If the manual hand wheel is not at the neutral position during control operation, it may
not work normally and its weak part may get damaged.
③If you use a pressure higher than the specified pressure on the name plate, the rubber
and O-rings of the actuator may be damaged and cause operation problems.

4. Maintenance and Repair
REGULAR INSPECTION
Repair and inspect as described below. If any malfunction occurs, take appropriate measures according to
the preventive maintenance procedures and troubleshooting in Chapter 6. Also, disassemble and inspect the
system during the regular overhaul period, and replace parts if necessary.
♣RECOMMENDATIONS
The life span of the valve can increase if you replace parts according to their replacement cycles. Refer to
the Part Replacement Cycle sheet shown below.
Part Replacement Cycle Sheet
Item Name Replacement Cycle Others
Piston O-ring 3 years
Piston Wearing 5 years
IRREGULAR INSPECTIONS
A) Are there abnormal noise, vibration or hunting?
B) Does air pressure escape from actuator?
C) Are there any loose bolts and nuts?
4.1 Valve Disassembly
- WARNING -
To prevent human injuries and damages to control system, remove instrument air and
signals from the valve, close the block valve and open the bypass valve to switch over
the pressure from the line to the bypass. Then slowly unfasten the bolts from the pipe
until the internal pressure of the body is completely released and remove the valve
before disassembling the actuator.

4.2 Disassembly and Assembly of Actuator
GENERAL INFORMATION
The Honeywell pneumatic cylinder actuator moves the piston in the cylinder pipe, which is transformed
into rotation and moves the valve. This procedure is to adjust the valve position to the required position
by responding to control signals using air pressure.
4.2.1 Disassembly (See Fig 4.1)
①Remove actuator from the valve.
②Release the air pressure from inside the actuator and disconnect the air piping.
③Replace 2 tension bolts and remove the others.
④Slowly remove the remaining 2 bolts while keeping the actuator spring without load.
⑤Remove the cylinder cover.
⑥Remove the pipe, and then remove the piston from the spindle.
⑦Remove the spindle from the arm while taking care not to damage the surface of the spindle,
and then pull out the arm from the housing.
⑧Check the O-ring and wearing, and replace them if necessary.
4.2.2 Assembly (See Fig 4.1)
Assemble in the reverse sequence of the disassembly.
- WARNING -
The components of a spring return type actuator are pressed down by a spring. Take
general safety measures and disassemble correctly. Otherwise, injuries and damages
may result.

5. Preventive Maintenance and Troubleshooting
♣NOTE
Check and replace actuator wearing and O-ring once every 3 years depending on the frequency of use. For
other parts, replace them to prevent damages to other devices when they show a wearing sign.
5.1 Troubleshooting
Table 5-1 shows some remedies to general problems that may occur at the site while using cylinder actuator.
For more serious problems, transport the system to the factory.
Table 5-1
Problem Solution
When actuator does
not operate
1. Check the air pressure supplied to the actuator.
2. Remove the actuator and check spring and piston.
Leak from actuator
components
1. Fasten the bolts on the cylinder frame.
2. Disassemble the actuator. Check the O-ring and wearing, and replace them with
new ones if they are damaged.
The stroke time is
delayed.
1. Check the air pressure supplied to the actuator.
2. Check the air pressure of the filter regulator.
3. Check the adjustment of accessories such as solenoid.
