Emerson KTM Series Manual

KTM SERIES EF190FE SPLIT BODY FLANGED BALL VALVES

INSTALLATION AND MAINTENANCE MANUAL

Before installation these instructions must be fully read and understood

1 USE

Long life of valves can be maintained under

normal working conditions and in accordance

with pressure/temperature and corrosion

datachart.

2 MANUAL OPERATIONS

The opening and closing of the valve is done by

turning the handle ¼ turn (90° turn).

A. Valve in open position

The handle is in line with the valve or pipeline.

B. Valve in closed position

The handle is perpendicular with the pipeline.

3 AUTOMATED OPERATIONS

Alignment between actuator and valve is

extremely important.

Misalignment will result high operational

torque, create the stem side loading and cause

early stem leakage.

4 GENERAL INFORMATION FOR ON-SITE

INSTALLATION

4.1 Remove plastic end flanges

protectioncovers.

5 DISASSEMBLY AND CLEANING

PROCEDURES

CAUTION

Ball valves can trap fluids in ball cavity when it is

in closed position.

5.1 If the valve has been used to control

hazardous media, it must be

decontaminated before disassembly. It is

recommended that the following steps be

taken for safe removal and reassemble.

A. Relieve the line pressure.

B. Place valve in half-open position

and flush the line to remove any

hazardous material from valve.

C. All persons involved in the removal

and disassembly of the valve should

wear the proper protective clothing,

such as face shield, glove, and apron,

etc.

5.2 Remove both counter flanges studsand

nuts and lift valve from line for

maintenance.

4.2 The valve may be fitted in any position on

the pipeline.

4.3 Before installing the valves, the pipes

must be flushed clean of dirt, burrs and

welding residues to prevent damage to the

seats and ball surface.

4.4 The pipeline must be free of tension.

5.3 Remove handle (item 18) or actuator set,

stemnut (item 16), lock saddle (item15),

belleville washers (item 14), gland

(item13), thrust washer(item 12) and

stem packing(item 11).

5.4 Remove body stud (item 7) and nuts

(item7a) to allow end cap (item 2)

separated from body (item 1). The ball seat

(item 5) in the end cap should come out.

Remove body gasket(item 6).

5.5 Rotate the stem to "close" position, thus,

the ball (item 3) can be taken out easily

frombody.

5.6 Take out the ball seat (item 5) from body

seatpocket.

5.7 Pull out stem (item 4) and remove the

stem seal (item 8 and 10) compress ring

(item 9). Atthis stage, all the parts are in

"Loose condition" and ready for inspection.

6 VISUAL INSPECTION

Clean and inspect metal parts. It is not

necessary to replace the ball and stem unless

the ball seating surfaces have been damaged

by abrasion or corrosion. Full replacements

of all soft parts are strongly recommended.

Thereplacement parts can be ordered in

"Repair kit" form.

INSTALLATION AND MAINTENANCE MANUAL

7 PROCEDURE TO CHANGE PARTS AND

ASSEMBLY

7.1 Install ball seat (item 5) to body (item 1)

seat pocket and make sure the spherical

curvature facing the ball.

7.2 Put lower stem seal (item 8), compress

ring (item 9) and upper stem seal (item10)

to stem (item 4) and slide the stem up

through the body. Install stem packing

(item 11) and top with thrust washer

(item12), gland (item 13), Belleville washer

(item 14), lock saddle (item 15) and drive

stem nut (item 16) per the stem torque

data to ensure the whole stem seals have

been properly compressed. Turn the lock

saddle to engage it with stem nut - this is

to prevent stem nut from unthreading.

7.3 Put the handle (item 18) on stem and

secure it with handle nut (item 16).

7.4 Turn the handle to "close" position. Line

up the ball slots with stem tang and slides

ball (item 3) into the position. Turn the

handle to "open" position to prevent the

ball from falling out.

7.5 Install the body gasket (item 6) into the

shoulder of the end cap (item 2), put the

ball seat (item 5) into seat pocket.

7.6 Put the end cap (item 2) into body with all

the holes line up between or end cap holes

guided by body studs and engaged.

7.7 Finger tight the body stud and nuts and

tighten one side snugly, then the one

diagonally across. Repeat for other bolts

or nuts until the torque is observed per

bolting torque data.

7.8 Cycle the valve slowly with gentle back

and forth motion to build gradually to full

quarter turn. By cycling slowly, the seat

lips will assume a permanent seal shape

against the ball.

7.9 If possible, test the valve before placing

it back to line for service to ensure "No"

through and external leakage is observed.
