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.
