1. General

1.1 Introduction to Valves

A) The ball valve has been designed for the requirements and applications of piping.

B) The most important feature of the Honeywell angle valve is its body that has been manufactured in

appropriate sizes to meet the requirements of piping. It consists of a body that includes a cage to

control flow speed, a seat ring, a bonnet, and an actuator.

C) The ball Valve is designed for easy maintenance.

D) The ball valve trim boasts a long life span and has few faults. To use the system 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 Ball valves. 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.

2. Storage

A) Do not throw, drop, trip or drag ball valves when transporting them.

B) Keep all parts of the ball valve 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.

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.

C) Operate the elastomer (O-ring type) of pneumatic 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.

D) Do not remove the flange cap attached to the flange surface to prevent foreign substances from

penetrating into the system until ball valves are installed on the line.

3. Installation

Like any other valves, the Honeywell control valve must be installed carefully at first according to the

following cautions to use it for many years without malfunction.

A) Remove the flange cap and check whether there are any foreign substances in the body. If you find

foreign substances, remove them before starting installation.

B) As cast steel products are processed with rust preventive oil before shipping to prevent corrosion,

remove the rust preventive oil from the pipes before installing them on the line.

C) Blow off all foreign substances including welding chips in the pipes before starting installation.

D) Install valves in the direction of arrow marked on the body.

♣CAUTIONS

When moving control valves, you should handle them carefully so that the components and air piping

will not be damaged. Otherwise, the electronic and electric parts such as solenoid valve, positioner, and

limit switch may get damaged or the valve travel may change.

Be careful not to damage the sealing surface of valve flange.

Apply thermal insulation as needed, but do not apply thermal insulation to the cooling fin and extensions.

- WARNING -

To prevent damages to plugs and seats, you must blow out (flashing) foreign

substances such as weld beads, scales and chips from the pipeline

according to the prescriptions before installing the ball valve.

E) When assembling the valve, you should use a specified gasket, and install it in parallel with the other

flange. Also, you are recommended to fasten the bolts in several parts in a balanced manner

sequentially in diagonal direction. (See Fig 3.1)

Fig 3.1 Procedure for Fastening Flange Bolts

F) Install the valve at right angle to the ground as much as possible. If this is impossible, attach a support to

the valve before installing it. (See Fig 3.2 and 3.3)

Fig 3.2 Installing Support Fig 3.3 Installation Location of Actuator

G) A minimum space is required for maintenance of the valve installation area. (See Fig 3.4) In addition, a

space for manual operation is required if a manual hand wheel has been installed.

☞ A: Face-to-Face Dimension

B: Minimum distance from obstacles (Approx. 30 cm)

C: Space for removing the actuator (Approx. 40 cm)

H) Install a bypass line for valve maintenance. (See Fig 3.5)

Fig 3.5 Example of Control Valve Installation

♣NOTE

When the control valve has a problem, you may have to close the block valve and open the bypass valve to

control flow. Therefore, use a control valve that has the feature to control flow by opening the bypass valve.

Moreover, it is ideal to choose the same flow characteristics and size as those of control valve. Fig 3.6

shows an example of ideal control valve installation recommended by Honeywell.

♣NOTE

To maintain a constant pressure at the entrance for all tracks of the valve, the straight pipe length at the

valve entrance must be at least 10 to 20 times the pipe diameter. For the fluid to maintain the specified

pressure after passing the valve and to prevent noise or vibration by turbulent flow, the straight pipe length

at the valve exit must be at least 3 to 5 times the pipe diameter. Straight piping at the entrance and exit

allows the preservation of accurate operation status by enabling accurate measurement of the pressure at

the entrance and exit. (See Fig 3.7)

4. Operation

4.1 Inspections before Operation

①Check whether there is any leak from all connections including the air pipe connections.

②To check whether there is any leak from gland packing and gaskets, apply a pressure to the pipeline. If

any leak is detected, remove pressure from the pipeline and fasten the gland flange nut.

③Check the bolts and nuts of the actuator and the yoke for any looseness.

④Check whether there is any short circuit in the electric signal system.

⑤Check whether the attached manual hand wheel is at the Neutral position.

⑥Check whether the system operates accurately and flexibly according to the signals from the controller.

⑦When raising the temperature or pressure, do it slowly. Never raise the temperature or pressure quickly.

⑧Check whether the air pressure required for valve operation is accurately set. (Cylinder Actuator:

5.0kgf/cm2-> Specified in the name plate)

⑨Electrical devices such as limit switch or solenoid valve are attached to an control valve. Even if the

manufacturer has adjusted them, the tubing may be bent or the valve stem’s position becomes incorrect

due to a shock during transportation or careless handling during assembly. Therefore, it is

recommended to readjust the valve during the test run.

- WARNING -

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.

5. 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

valve body and actuator 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.
