1.2 General Notes
The following instructions refer to KLINGER Die Er-
ste Wafer Type and Flanged V-notch Segment Ball
Valve with soft seat and metal seat as described in
the KLINGER Die Erste current catalog.
Keep the protective covers in place until the valve is
ready for installation. Valve performance depends
upon prevention of damage to ball surface. After re-
moving the cover make sure that the valve is com-
pletely open and free of obstructions, dirt, particles
or any materials that may cause seat or seal dam-
age.
Valves may contain a silicon-based lubricant for
transportation, which aids in the assembly of the
valve. Lubricant may be removed with a solvent if
found objectionable. Alternatively valves can be or-
dered free of lubricants upon request.
Certain ferrous valves contain phosphate material,
and are oil dipped during the course of manufac-
ture. However, the processes used are completely
non-toxic.
1.3 Precautions and Warnings
Choose the correct material of valve for different
applications before obtaining the valve. The user
should be aware of the operating situation, fluid
properties, and the possible outcomes when imple-
menting valves into the pipeline system. KLINGER
Die Erste suggests that the user should make esti-
mation beforehand.
Fluid undergoes property changes with respect
to outside factors, particularly fluid left inside the
sealed cavity. When temperature and pressure ex-
ceed allowable value, valve failure may occur. User
should be aware of that excessive pressure and
temperature at nearby pipeline system can also
cause valve failure as well.
Wafer Type and Flanged V-notch Segment Ball
Valves are generally recommended for throttling
services as well as on-off functions.
Do not touch the valve surface when high tempera-
ture fluid is flowing through the valve.
Do not attempt to open the bonnet and the cap
during operation, especially with the presence of
high pressure in the pipeline system.
For safety concern, unstable fluid should not be
used in the pipeline system, unless otherwise spec-
ified with the category III in Declaration of conformi-
ty.
NOTE:
1. KHD-SGF Wafer Type and Flanged V-notch Seg-
ment Valves are installed between flanges. The
body is in one part; the shaft and segment ball are
separated.
2. The valve is either soft or metal seated. De-
pending on customers' requirement, the structure
of the supplied valve may be different.
3. The valve is designed for both control and shut-
off applications.
4. Actuators and accessories are only discussed
briefly. Please refer to individual manuals for fur-
ther information on their IOM manuals.
CAUTION:
Before removing valve from pipeline, operator
should be aware of that: media flowing through
the valve may be corrosive, toxic, flammable, or
of a contaminant nature. Where there is evidence
of harmful fluids having flowed through the valve,
the utmost care must be taken. It is suggested

Installation
Flush the pipeline carefully before installing the
valve. The particles of dirt or debris or welding may
damage the segment sealing surface and seats.
Also, before installing, check all valve and mating
flanges to ensure gasket surfaces are free from de-
fects.
2.1 General Notes
1) Direction
The valves are designed with a preferred flow di-
rection. Install the valve according to the direction
marked on the valve body. Valve installed with re-
versed flow direction will not seal properly.
Figure 2.1 Flow Direction Indication
In the case of valve automation with actuators, in-
stall the valves with the actuator at or above the
centerline of the horizontal piping, as shown in Fig-
ure 2.1.
CAUTION:
Do not fasten supports to the flange bolting or the
actuator.
NOTE:
User should avoid installing the valve so that the
shaft point downwards because impurities travel-
ing in the pipeline may enter the body cavity and
damage the gland packing.
1.4 Storage
If the valves are not to be installed immediately,
please store the valve carefully before installation,
preferably indoors in a dry and clean place.
Also, the valve ports should be sealed by plastic
caps to prevent dirt from entering and damaging in-
ner parts.
Note:
1. The valve is delivered in the closed position. Be-
fore storing, check to see that the valve is in the
CLOSED position in order to avoid damage to the
seal.
2. The surface of the valves should be greased
properly for protection.
that the following safety precautions should be
taken when handling valves.
1) Always wear eye shields.
2) Always wear eye shields.
3) Always wear gloves and footwear.
4) Wear protective headgear.
5) Ensure that running water is readily accessible.
6) Fire extinguisher must be obtainable if media is
flammable.
Check the line gauge to ensure that no pressure is
present at the valve. Ensuring media is released by
operating valve slowly to the half open position.
Ideally, the valve should be decontaminated when
the ball is in the half open position.
These valves, when installed, have body connectors
which form an integral part of the pipeline and the
valve cannot be removed from the pipeline without
being dismantled- see DISMANTLING section for
reference.
CAUTION:
Do not exceed the valve performance limitation.
CAUTION:
Before installing, make sure the line pressure has
been relieved, and any hazardous fluids have been
drained or purged from the system.

Figure 2.2 Proper position while piping
NOTE:
When installing horizontally, the support of the ac-
tuator must be strengthened to avoid valve leak-
age caused by valve stem deflection.
2) Position
The body, cap and gasket are in the connection area
of ball valve and pipeline. The bear weight ability
and gradient are very important to the pipe instal-
lation. Do not make the pressure from the pipeline,
and stress to concentrate on the connecting area of
body and cap. Ball, seat, and stem will be damaged.
Consequently, deformation and leakage may occur.
3) Fittings
Select the correct size of fittings according to the
pipeline specification. Tighten the segment valve
to the pipeline adequately with appropriate bolts.
Do not attempt to correct pipeline misalignment by
means of flanged bolting.
4) Systems hydrostatic test
Before delivery, valves are tested 1.5 times the al-
lowable pressure at ambient temperature in open
position. However, after installation, the piping sys-
tem may subject to system tests, as condition not
to exceed the marking pressure.
5) Pre-Installation Wash
Before the valve installation, clean the pipeline sys-
tem to remove any foreign deposits by water. Clean
the connecting wafer end surfaces as well to ensure
tight sealing.
2.2 Installation of Ends
1) Wafer End
1. Verify valve is in the fully OPEN position.
2. Use the appropriate size bolt and heavy hex nut
(not included) as recommended for flange size
and class.
3. Do not over tighten the joints bolting.
4. Place gasket on each flange connection (not in-
cluded).
5. Follow gasket manufacturer’s recommended
practice for tightening flange bolts.
2) Flanged End
1. Before installing the valves, make sure the
flanges and the pipe are free from grit, dirt or
burrs.
2. The flanges must be aligned and parallel with
the correct distance to allow the valve face-to-
face dimension and gaskets to fit between.
3. Tighten the flange bolts in a crossover pattern,
with a torque values determined by the gasket
manufacturer, other variables like gasket type
and material, bolt, flange and lubricant affect the
