KTM SERIES EF190FE SPLIT BODY FLANGED BALL VALVES
INSTALLATION AND MAINTENANCE MANUAL
Before installation these instructions must be fully read and understood
Emerson.com/FinalControl VCIOM-03153-EN 18/07© 2017 Emerson. All Rights Reserved.
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.
