Kammer Control Valves
WARNING:
Disconnect or loosen the fastners –
particularly between bonnet and housing – only after
the valve has been removed. When reinstalling, tighten
the bolts as specified in these maintenance instructions
using a torque wrench.

TRANSPORT AND STORAGE
Handle, transport and store FLOWSERVE control
valves carefully.
2.1
Store the valve in its protective packaging and/or with
the protective caps on the connection ends. Valves
heavier than approx. 10 kg should be stored and
transported on a pallet (or similarly supported, where
applicable also on the installation site).
WARNING:
Do not place unpackaged valves on dirty
surfaces with the flange sealing surfaces. Hard and/or
sharp particles can damage the plastic lining.
2.2
During storage before installation, the valves should be
stored in a closed room as a rule and protected against
damaging influences such as dirt or moisture.
2.3
Large valves can be picked up using hoisting belts on
the yoke stems / eyes or - if present – on the supporting
shackles provided for this purpose. If hoisting belts are
used for unpacking, connect them so that the outer
piping and attached parts are not damaged.
WARNING:
If hoisting belts are used, the center of
gravity of the valve can be higher than the connection
point. In such cases, secure the valve against turning or
support it to prevent injury or property damage.
In the event of transport damage, please contact your
FLOWSERVE representative immediately.

INSTALLATION
3.1
General
The same instructions apply for installing FLOWSERVE
control valves in a pipeline as for connecting pipes and
similar piping elements with plastic liner materials. For
control valves, the following instructions apply in addi-
tion. Observe Section 3 for transport at the installation
site.
WARNING:
Handle valves with particular care and
observe instructions for flange connections.
NOTE:
As a rule, additional flange seals are not
required.

WARNING:
Protection against incorrect use of control
valve:
In particular, it is necessary to ensure that the selected
coating on the valve parts in contact with the medium
a r e s u i t a b l e f o r t h e m e d i u m s , p r e s s u r e s a n d
temperatures encountered. The manufacturer is not
responsible for damage to the valve resulting from
corrosive mediums.
Failure to observe these precautions can pose a danger
for the use and cause damage to the piping system.
1.3.2 The piping system and control system must be installed
properly and checked regularly. The wall thicknesses of
the FLOWSERVE control valves correspond to the
standards and regulations for the pressure stage
requirements of the piping system in question.
1.3.3 The valves must be connected properly to this system.
1.3.4 The usual flow rates in continuous operation are not
exceeded in this piping system and abnormal operating
conditions such as vibration, water hammer, cavitation
and excessive quantities of solids in the medium –
particularly abrasive solids – must be clarified with the
manufacturer.
WARNING:
At temperatures > +50
°
C and < - 20
°
C, it is
necessary to provide for protection against touching
including the piping connections.
1.4
Particular dangers
DANGER:
The valve stem is sealed with a packing gland.
Before loosening or unscrewing the packing nut , ensure
that the pressure in the pipeline is completely relieved so
that the medium cannot escape through the packing.
Observe the usual safety precautions for hazardous
medium – particularly protective clothing – when
working on the valves.
DANGER:
On valves with a bellows seal also ensure that
the bellows does not leak by using a test connection, if
present, before removing the packing gland nut.
DANGER:
Before removing the valve from the pipeline,
ensure that the pressure in the pipeline is completely
relieved so that the medium does not escape
uncontrolled from the line.
WARNING:
.If it is necessary to remove a valve from the
pipeline, medium can escape from the line or from the
valves. In the case of mediums which pose a health
danger or other danger, ensure that the pipeline is
completely purged before removing the valve.
Observe caution with residues flowing out of the line or
remaining in the dead chambers of the valves. In the
case of dangerous mediums, observe the usual safety
precautions – particularly protective clothing.
