1USING KÄMMER VALVES AND ACTUATORS
CORRECTLY
1.1General
The following instructions are designed to assist in
unpacking, installing and performing maintenance as
required on Kämmer products. Product users and
maintenance personnel should thoroughly review this
bulletin prior to installing, operating or performing
any maintenance.
DANGER:
are designed for specific applications (e.g. with regard
to medium, pressure, temperature). For this reason
they should not be used in other applications without
first contacting the manufacturer.
1.2Terms concerning safety
The safety terms DANGER, WARNING, CAUTION and
NOTE are used in these instructions to highlight
particular dangers and/or to provide additional
information on aspects that may not be readily

information, which may not be very obvious even to
qualified personnel. Compliance with other, not
particularly emphasised notes, with regard to
transport, assembly, operation and maintenance and
with regard to technical documentation (e.g. in the
operating instruction, product documentation or on
the product itself) is essential, in order to avoid faults,
which in themselves might directly or indirectly cause
severe personal injury or property damage.
1.3Protective clothing
Kämmer products are often used in problematic
applications (e.g. extremely high pressures, dangerous, toxic or corrosive mediums). In particular
valves with bellows seals point to such applications.
When performing service, inspection or repair
operations always ensure, that the valve and actuator
are depressurised and that the valve has been cleaned
and is free from harmful substances. In such cases
pay particular attention to personal protection
(protective clothing, gloves, glasses etc.).
1.4Qualified personnel
Qualified personnel are people who, on account of
their training, experience and instruction and their
knowledge of relevant standards, specifications,
accident prevention regulations and operating
conditions, have been authorised by those responsible
for the safety of the plant to perform the necessary
work and who can recognise and avoid possible
dangers.

1.6Spare parts
Use only Kämmer original spare parts. Kämmer
cannot accept responsibility for any damages that
occur from using spare parts or fastening materials
from other manufactures. If Kämmer products
(especially sealing materials) have been on store for
longer periods check these for corrosion or deterioration before using these products. Fire protection for
Kämmer products must be provided by the end user.
1.7Service / repair
To avoid possible injury to personnel or damage to
products, safety terms must be strictly adhered to.
Modifying this product, substituting nonfactory parts,
or using maintenance procedures other than outlined
in this instruction could drastically affect performance
and be hazardous to personnel and equipment, and
may void existing warranties. Between actuator and
valve there are moving parts. To avoid injury
Flowserve provides pinch-point-protection in the form
of cover plates, especially where side-mounted
positioners are fitted. If these plates are removed for
inspection, service or repair special attention is
required. After completing work the cover plates must
be refitted.
Apart from the operating instructions and the
obligatory accident prevention directives valid in the
country of use, all recognised regulations for safety
and good engineering practices must be followed.
WARNING:
STOP!
for repair or service Kämmer must be provided with
Before products are returned to Kämmer
a certificate which confirms that the product has been
decontaminated and is clean. Kämmer will not accept
deliveries if a certificate has not been provided (a form
can be obtained from Kämmer).
1.8Storage
In most cases Kämmer Products are manufactured
from stainless steel. Products not manufactured from
stainless steel are provided with an epoxy resin
coating. This means that Kämmer products are well
protected from corrosion. Nevertheless Kämmer
products must be stored adequately in a clean, dry
environment. Plastic caps are fitted to protect the
flange faces to prevent the ingress of foreign
materials. These caps should not be removed until
the valve is actually mounted into the system.
1.9Valve and actuator variations
These instructions cannot claim to cover all details
of all possible product variations, nor in particular
can they provide information for every possible
example of installation, operation or maintenance.
This means that the instructions normally include only
the directions to be followed by qualified personal
where the product is being used for is defined
purpose. If there are any uncertainties in this respect
particularly in the event of missing product-related
information, clarification must be obtained via the
appropriate FLOWSERVE sales office.
2UNPACKING
2.1Each delivery includes a packing slip. When unpacking, check all delivered valves and accessories using
this packing slip.
2.2Larger valves can be lifted using slings on the yoke
rods or, if present, on the lugs provided for this purpose. If slings are used, attach them so that the outer
tubing or attaching parts are not damaged.
WARNING:
of gravity of the valve may be above the lifting point.
STOP!
If slings are used, be aware that the centre
In this case, secure or support the valve against rotating, to prevent damage or personnel injury.
2.3Report transport damage to the carrier immediately.
2.4In case of discrepancies, contact your nearest
FLOWSERVE sales office.
3 INSTALLATION
3.1Clean tubing prior to installing.
3.2If possible, install the valve in an upright position (actuator on top), to ease maintenance. An upright installation position is important with low-temperature
applications, in order to keep the distance between
the packing material and the medium as large as possible. The packing material then retains the ambient
temperature as much as possible.
NOTE:
Do not insulate extension bonnets that are pro-
vided for hot or cold services
3.3Make sure that sufficient overhead clearance above
the actuator is maintained, to allow for disassembly
of plug from the valve body (see following table).

3.4After installing, check direction of flow again. The direction of flow is shown by the arrow on the housing.
3.5If the valve is to be welded into the line, make sure
that the valve is shielded from excessive heat.
3.6Connect supply pressure and signal lines. Control
valves are supplied with a positioner. The end connections for supply pressure and signal are clearly
marked. Actuator and positioner are suitable for max.
4.2 bar (60 psi) supply pressure. If the supply pres-

sure exceeds the pressure specified on the nameplate,
a pressure reducing station is required. If instrument
air is not available, install an oil separator/air filter in
the air inlet line. All connections must be leak free.
4QUICK CHECK:
Before operating, check the valve as follows:
4.1Open and close the valve, and observe the movement
of the actuator stem. The movement must be smooth
and linear.
4.2Check for maximum stroke through change of signal
(for pneumatic positioners, 0.2 - 1.0 bar or corresponding split-range values; for IP positioners, 4-20
or 0-20 mA).
4.3Check all air connections for leaks.
4.4Tighten packing nut (see table 1).

5.7Check all accessories for firm seating.
5.8If possible, close supply pressure and check the failsafe position.
5.10Check stem boot for wear.
4.5Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes
as defined.
4.6After use at fluctuating temperatures, re-tighten all
bolt connections and check for leaks.
5MAINTENANCE
Check valves for correct functioning at regular
intervals (at least once every 6 months) as follows.
This check can be made when installed and in many
cases without interrupting production. If internal
defects are suspected, see section „Disassembly and
Assembly of Valve“.
5.1Examine gaskets for leaks and if necessary re-tighten
bolts (see Fig. 1).
5.11Check actuator for leaks. To do this, spray housing,
air connections and plug stem guide with leak spray
and check for any bubble formation.
5.12Clean plug stem.
5.13Check air filter, if present, and if necessary replace
insert.
Note:
For further information regarding service and
maintenance please contact your nearest
FLOWSERVE office.
DANGER:
On actuators with aluminium cases the
actuator springs must be renewed with original spare
parts every 10 years or after 50.000 operating hours
which ever occurs first.

working on the actuator. Failure to do so can cause
Depressurise the line to atmospheric
serious injury.
6.1.2Remove cap and nameplate. Tighten zero adjusting
nut until it just touches the surface of the spring
housing. This relieves the plug from actuator spring
pressure. If the actuator is fitted with a handwheel
this can be used to relieve the plug from actuator
spring pressure.
6.1.3Using a wrench, secure the actuator stem against
turning and using a second wrench loosen the stem
locknuts. If the actuator is fitted with a coupling refer to the procedure described in the maintenance
instructions for the I/P actuator.
CAUTION:
The actuator stem must not be rotated,
as this will cause damage to the diaphragm.
6.1.4Loosen gland and clamp nuts.
6.1.5Secure plug stem against turning and unscrew actuator from plug stem by rotating counter-clockwise.
CAUTION:
Ensure that the plug assembly is not rotated with the plug seated. This may cause irreparable damage to the seating faces.
6.1.5Remove actuator and remove at the same time locknut, travel indicator disc, gland nut and clamp nut.
3.2Install series 3 actuator
Information:
•Before the actuator is installed, it must be calibrated according to section 3 of the instructions
„Pneumatic and Electro-pneumatic Actuators“.
•All worn or damaged parts must be replaced.
Reusable parts must be clean.
6.2.1Position actuator with clamp nut, gland nut, locknuts and travel indicator disc on the valve.
6.2.2Only for „spring-to-close“ actuators:
Screw actuator onto plug stem by rotating clockwise, until the yoke plate just touches the valve housing and the actuator is aligned forward. If the actuator is fitted with a coupling refer to the procedure described in the maintenance instructions for
the I/P actuator.
CAUTION:
Ensure that the plug assembly is not rotated with the plug seated. This may cause irreparable damage to the seating faces.
Only for „spring-to-open“ actuators:
Lift plug stem and screw it into the lower coupling
half until the distance between „plug in seat“ and
„plug raised“ approximately corresponds to the specified stroke.
6.2.3Tighten clamp nut and gland nut.
6.2.4Adjust seat tightness by screwing/unscrewing the
plug stem in/out of the actuator stem.
CAUTION:
Ensure that the plug assembly is not rotated with the plug seated. This may cause irreparable damage to the seating faces. Open valve, make
adjustment, close valve and check for leaks. If the
valve is fitted with a bellows seal the plug stem may
NOT be rotated at all. In the case of a bellows seal
adjustments are made with the coupling.
6.2.5After adjusting, secure the locknuts and the travel
indicator disc lying between them against actuator
stem and align the travel indicator on the yoke rod.
6.3Remove series 2 actuator
(see Fig. 1a)
For series 4 actuator see 6.1
6.3.1Shut off air supply.
WARNING:

serious injury.
6.3.2Disconnect all tubing.
6.3.3Remove 2 screws and remove coupling.
6.3.4Remove yoke rod retaining nuts and lift actuator
assembly from the valve.
6.3.5Remove coupling insert and it’s locknut from plug
stem.
NOTE:
Ensure that the plug assembly is not rotated
with the plug seated. This may cause irreparable
damage to the seating faces.
6.4Install series 2 actuator
(see Fig. 1a)
The actuator stem must be fully extended:
Actuators with air-to-open action must be fully
vented. Actuators with air-to-close action apply
supply pressure.
Manually depress the plug stem to ensure the plug is
fully seated.
6.4.1Screw coupling insert locknut and coupling insert as
far as possible onto plug stem.

7DISASSEMBLE AND ASSEMBLE VALVE
General Information
We recommend separating the actuator from the
valve before commencing repair work.
However, many maintenance and adjusting operations can be carried out with the valve installed.
NOTE:
Never rotate the plug or perform any service
on the valve while the plug is seated in the seat ring.
Doing so may cause irreparable damage to the trim
set. To ensure against this, always hold the plug out
of the seat while working on the valve assembly.
7.1Disassemble valve
7.1.1Disconnect actuator from valve body
7.1.2Hold the plug out of the seat. Using a 41 mm wrench
loosen and unscrew the bonnet nut and remove the
bonnet from the valve.
7.1.3Carefully extract the plug from the bonnet. Note that
the threaded section of the plug stem is slightly
smaller in diameter than the guided section, this helps
prevent damage to the packing when removing the
plug from the bonnet.
7.2.5Replace packing by inserting packing rings one at a
time tapping each one down with a suitable bushing.
NOTE:
ensure that the gaps in the packing rings are
distributed evenly around the circumferance in the
packing box (gaps not in line).
Different packings and fitting sequence is shown in
the spare parts list.
7.2.6Insert packing follower. Fit gland nut for transport
purposes only. Gland nut to be fitted correctly and
tightened down when the actuator is mounted.
7.1.4Remove the packing follower, packing rings and guide
bushing and clean the packing chamber.
7.1.5Remove the bonnet gasket.
7.1.6Remove seat and seat gasket.
7.1.7Clean and inspect all parts.
7.2Assemble valve
Attention: All worn or damaged parts must be re-
placed. Reusable parts must be clean. All consumable items such as seals, and gaskets must always
be renewed.
7.2.1Replace seat gasket and seat ring.
7.2.2Replace bonnet gasket.
7.2.3Insert the plug into the bonnet. Install the guide bushing into the packing chamber with bevelled end facing down and insert the bonnet in the valve body.
7.2.4Coat the bonnet nut threads with a small amount of
lubricant. Hold the plug stem fully retracted in the
bonnet and thread the bonnet nut onto the body. Using a 41 mm torque wrench torque the bonnet nut to
150 Nm.
