Emerson KTM 2-WAY Manuale

INSTALLATION

Refer to Figure 1

1. Valves are bi-directional as standard, unless

otherwise stated, and may be fitted in either

direction.

2. Installation may be carried out with stem

displaced through any angle permitted by

the bolting.

3. Remove protective covers from valve faces.

4. Ensure that mating flanges and gaskets are

clean and undamaged.

5. Should there be any possibility of abrasive

particles (weld slag, sand etc.) within the

piping system, this could damage valve

seating areas. The system will need to be

flushed clean.

6. Ensure mating pipe flanges are aligned

correctly, bolting should be easily inserted

through mating flange holes.

7. Fit the valve into pipework ensuring easy

access of the lever/handwheel.

8. Tighten the flange bolts in a diagonal

pattern. Uneven tightening could cause

leakage or gasket damage.

9. When sealing tape or sealing gel type

material is used, ensure that no torn off

piece or solidified fragment get into the

pipe system.

Storage

When valves are to be stored for some time

before being fitted, storage should be in the

original delivery crates with any waterproof

lining and/or desiccant remaining in place.

Storage should be off the ground in a clean,

dry, indoor area. If storage is for a period

exceeding six months the desiccant bags

(ifsupplied) should be changed at this interval.

The ball valves are delivered with the ball in

full open position and should be stored as they

are. Keeping the ball in other position or half

opened position for an extended period of time

could cause seat leakage.

Protection

Valves are delivered with protection according

to customer’s specification, or in accordance

with the quality assurance manual, to protect

the valve seats and closure member from

damage. Wrapping and/or covers should be left

in place until immediately before fitting to the

pipe.

These instructions summarize the main

warnings concerning the routine operations

asper the related installation and maintenance

manual.

Before installation these instructions must be read fully and understood

FIGURE 1 Selection

Ensure the valve’s materials of construction

and pressure/temperature limits shown on the

identification plate are suitable for the process

fluid and conditions. If in doubt contact the

manufacturer.

Transportation

• When lifting the ball valve by crane or hoist,

avoid hooking to inadequate areas of the

valve. Inadequate hoisting could cause

deformation of the valve or falling of the valve.

• Do not carry the valve by its handlever, or the

valve could drop down which will damage the

valve or injure the person.

MAINTENANCE

Refer to Figure 3

No routine maintenance is required other

than periodic inspection to ensure satisfactory

operation and sealing. Any sign of leakage

from the gland packing should be addressed

immediately by depressurizing the valve and

tightening the gland screws gradually and

evenly. If no further adjustment is possible,

or if seat or joint leakage is suspected, the

valve will require a complete overhaul. This

should be carried out after depressurization

and in accordance with specific maintenance

Instructions. Only original spares should be

used.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

PRESSURE TEST

• In case of pressure test of the pipe system,

the valve should be in a half-open position

and check the leakage from joint connection

or gland. If the test is performed with the

valve in close position, overload pressure on

the seat could cause seat leakage.

• The ball valve should be operated to either

full open or closed position. Prolonged use

in a half-open position could cause seat

deformation or seat leakage.

OPERATION

Refer to Figure 2

• The closed position of KTM ball valves is

indicated by either the handlever or the

direction of the parallel flats on the top of

the stem (see picture).

• All standard manually operated valves are

‘clockwise to close’.

• The valve requires no ‘additional tightening’

to shut off, excessive handle operation could

break the lever, injure the operator, or deform

the stopper or stem which may lead to seat

leakage.
