KEYSTONE OPTISEAL F14/16 - 15/17 AND BREWSEAL BUTTERFLY VALVES

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Before installation these instructions must be fully read and understood

4. Ozone: storage rooms should not
contain any equipment generating ozone.
E.g.lamps, electric motors.

IMPORTANT

Before valves are being installed or used
thefollowing actions are recommended.

1. Valves/parts have to be inspected and
thoroughly cleaned if required.

2. Rubber parts need to be greased with silicone
grease if not present anymore.

3. All surfaces in contact with seats have to be
thoroughly cleaned and greased with silicone
grease if stored for more than 5 months.

1.2 Handling

To prevent damage during handling,

Intended valve use

The valve is intended to be used only in
applications within the pressure/temperature
limits indicated in the P/T diagram of
theproduct manual.
When the valve is used in an end-of-line function,
PED Cat-I applications are allowed only. For
other categories, please contact thefactory.

1 STORAGE AND HANDLING

1.1 Storage

When valves are to be stored for some time
(2months or more) before being fitted, storage
should be in the original delivery crates
orcases.

1.1.1 Storage conditions

The valves should be stored off the ground
inaclean, dry indoor area.
Protect the valve from temperature and
humidity extremes, and exposure to excessive
dust, moisture, vibration, deformations,
sunlight and ozone.

thevalves should be lifted by hand or using
appropriate lifting equipment. The valves
should be protected from external events e.g.
(bumps,hitting and vibration) during transport.
Any flange protection caps need to be removed
before the valve is mounted in the pipeline.
Lift the valve with great care from the transport
package (crate, pallet). While handling or
installing the valve, ensure that no damage
occurs to the valve, the pneumatic/electrical/­hydraulic actuator or other instrumentation.

2 SPARE PARTS

Only original Keystone spare parts are
allowed to be used. Safe operation can not be
guaranteed if third party spare parts are used.

Recommendations

1. Temperature: storage temperature below
25°C, above 0°C preferable below 15°C.

2. Humidity: storage conditions should be such
that condensation does not occur, store in
a dry environment. Maximal 50% relative
humidity.

3. Light: valve rubbers should be protected
from light, in particular direct sunlight or
strong artificial light with high ultra violet.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

3 INSTALLATION

WARNING!

For safety reasons, it is important to take the
following precautions before you start work on
thevalve:

1. Personnel making any adjustments to
thevalves should utilize suitable equipment.
All required personal protection means
shouldbe worn.

2. The line must be depressurized before
installing the valve.

3. Installation and handling of valves should be
done only by personnel that is trained in all
aspects of manual and mechanical handling
techniques.

4.

Misuse of the valve is not allowed.
Forexample: the valve, handles, actuators or
other parts may not be used as ‘climbing tools’.

5. Ensure that valve pressure/temperature
limitations marked on the identification tag
are within the service conditions. The trim
number on the valve’s tagplate identifies
the valve materials. See Product Manual for
valve specific P/T diagram and trim number
definition.

6. Ensure that valve materials are compatible
with the pipeline fluid.

7. For DVGW-Gas approved lugged valves,
through threaded rods must be used instead
of flange bolts.

- If the flange (or pipe) is provided with a
raised face, the diameter of this shall be at
least 8 mm larger than the YY-dimension of
thevalve.

The use of the flange-gaskets is not allowed
since it might damage the valve.
The Keystone seat-face design eliminates
theneed for the gaskets.
Use flange bolting in agreement with
appropriate standard.

Do not use flange gaskets, these lead to
valvedamage!

3.3 Valve installation

The valves are bi-directional and may be
fitted in either direction relative to the flow.
The valvewill control flow equally in either
direction. Therecommended installation
position is shaft horizontal and the lower disc
edge opening down-stream. (Especially for
slurry service and media with a tendency for
sedimen tation). For optimum valve control and
smooth performance, it is recommended to
have a 10to 20 pipe diameters of straight run
inlet piping and 3 to 5 pipe diameters straight
outlet piping.
A valve is no crow-bar. Do not use the valve
to spread the flanges. Seat damage might be
theresult.

3.1 Visual valve inspection

1. Confirm that the materials of construction
listed on the valve nameplate are
appropriate for the service intended and
areas specified.

2. Tag/name plate identification

Manufacturer: Keystone
Fig.: e.g. OptiSeal 14-112
JOB: Job number
Nominal size: DN
M.P.W.P.: maximum permissible

working pressure
Flange compatibility: e.g. PN 10/16
Temperature: e.g. -40/120°C
Body: e.g. GJL 250.

3.2 Flange and pipe compatibility

Check matching of flange drilling pattern
ofvalve and pipe before assembly.
Flanges have to meet the following
requirements:

- The face inside diameter should be:
D min.: the valve Q-dimension + adequate

disc clearance.

D max.: the optimum inside diameter (ID)

is equal to the inside diameter of flange
standard EN 1092-1, table 8, type 11.
Forlarger than D max inside diameters or
other flange types please contact your local
Emerson Sales organization, as larger inside
diameters might result in reduced valve
functionality.

KEYSTONE OPTISEAL F14/16 - 15/17 AND BREWSEAL BUTTERFLY VALVES

INSTALLATION AND MAINTENANCE INSTRUCTIONS

NOTES

• The valve can be installed in the pipe-line either with

or without the actuator mounted on top of the valve.
Make sure that you can turn the disc cautious so you
can feel a mismatch resulting from a disc touching
the adjacent piping.

• It is the responsibility of the valve user - and not the

valve manufacturer! - to ensure that the pipeline
system has been built professionally and the valve
has been properly installed.

• Adjacent piping must be positioned so that minimal

piping stresses are transmitted to the valve flanges
during or after installation.

• Handling and lifting of the valves during installation

MUST be performed following the same instructions
described in previous section ‘1.2 Handling’.

IMPORTANT

Mating flange faces should be in good condition
and free of dirt and/or inclusions. Both pipe
insides to be well cleaned.

3.3.1 Existing system (see sketch)

1. Check whether the flange distance

meets the valve face-to-face dimensions.
Spreadwith adequate tooling the flanges
foreasy insertion of the valve.

2. In case of a wafer valve, insert some flange

bolts in the pipe flanges, to help you bear
the valve after insertion.

3. Close the valve so far, that the disc edge is

at least 10 mm within the body.

4. Insert the valve between the flanges, center

the valve body and insert all flange bolts.
Tighten the flange-bolts hand tight.

5. Slowly open the valve completely.

(Thediscis in line with parallel flats or
keyway in stem head. Keyway points
towards discedge).

6. Maintain the valve flange alignment while

gradually removing the flange-spreaders
and tighten the flange-bolts hand tight.

7. Slowly close and open the valve to check

foradequate disc clearance.

8. Cross-tighten all bolting to the proper

torque. Do not over tighten.

5. Finish-weld the flanges to the pipe and
allow the flanges to cool completely.

6. Install the valve now according to the
procedure for installing in existing systems.

3.4 Valve verification

Check the operation of the valve by operating
it to ‘full open’ and ‘full close’. To verify the
valve operation, the disc position indicator
on the actuator or the handle should rotate
between the ‘full open’ and ‘full close’
indicators on theactuator or throttle plate.
Generallythevalve disc travels clockwise
toclose.

3.3.2 New system (see sketch)

1. With the disc in near-closed position center
each mating flange with the valve body.
Fixthebody with some flange-bolts and
tighten the bolts.

2. Use the flange-valve-flange assembly
forfit-up and centering to the pipe.

3. Tack-weld the flanges to the pipe.

4. Remove the bolting and remove the valve
from between the flanges.

IMPORTANT

Do not finish-weld the flanges to the pipe with
thevalve bolted between the flanges as this will
result in serious heat-damage to the seat.
