1 USING KÄMMER VA LVES AND ACTUATORS
CORRECTLY
1.1 General
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: In most cases Kämmer valves and actuators
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.
1.2 Terms 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
apparent.
DANGER: indicates that death, severe personal injury
and/or substantial property damage will occur if proper
precautions are not taken.
WARNING: indicates that death, severe personal injury
and/or substantial property damage can occur if proper
precautions are not taken.

NOTE: indicates and provides additional technical
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.
1.3 Protective 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.).
1.4 Qualified 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.
1.5 Installation
DANGER: Before installation check the order-no,
serial-no. and/or the tag-no. to ensure that the valve/
actuator is correct for the intended application.
Do not insulate extensions that are provided for hot
or cold services.
Pipelines must be correctly aligned to ensure that the
valve is not fitted under tension.

2 UNPACKING
2.1 Each delivery includes a packing slip. When unpacking,
check all delivered valves and accessories using this
packing slip.
2.2 Larger 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: If slings are used, be aware that the centre
of gravity of the valve may be above the lifting point. In
this case, secure or support the valve against rotating,
to prevent damage or personnel injury.
2.3 Report transport damage to the carrier immediately.
2.4 In case of discrepancies, contact your nearest
FLOWSERVE sales office.
3 INSTALLATION
3.1 Clean tubing prior to installing.
3.2 If 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
provided for hot or cold services
3.3 Make sure that sufficient overhead clearance above
the actuator is maintained, to allow for disassembly
of plug from the valve body (see following table).
3.4 After installing, check direction of flow again. The diretion of flow is shown by the arrow on the housing.
3.5 If the valve is to be welded into the line, make sure
that the valve is shielded from excessive heat.
3.6 Connect 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-
1.6 Spare 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 deterior-ation before using these
products. Fire protection for Kämmer products must
be provided by the end user.
1.7 Service / 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: Before products are returned to Kämmer
for repair or service Kämmer must be provided with
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).
1.8 Storage
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.
1.9 Valve 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.

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.
4 QUICK CHECK:
Before operating, check the valve as follows:
4.1 Open and close the valve, and observe the movement
of the actuator stem. The movement must be smooth
and linear.
4.2 Check 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).
4.3 Check all air connections for leaks.
4.4 Tighten packing nut (see table 1).
NOTE: An excessively tightened gland nut can cause
excessive packing wear and can hinder the free movement of the plug stem.
4.5 Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes
as defined.
4.6 After use at fluctuating temperatures, re-tighten all bolt
connections and check for leaks.
5 MAINTENANCE
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“.
5.1 Examine gaskets for leaks and if necessary re-tighten
bolts (see Fig. 1).
5.2 Check bellows gasket and test connection - if present
- for external leaks.
5.3 Check valve for damage caused by corrosive residues
or corrosive vapours.
5.4 Clean valves and repaint as necessary.
Warning: To prevent a buildup of electrostatic charge
clean the actuator/valve with a damp cloth only.
5.5 Check gland nut for correct torque (see table 1)..
NOTE: An excessively tightened gland nut can cause
excessive packing wear and can hinder the free movement of the plug stem.
5.6 If possible, open and close valve and check for maximum stroke and smooth movement of the plug stem.
Irregular movement of the plug stem may indicate
internal defects.
NOTE: With graphite packing, irregular movement of
the plug stem is normal.
WARNING: Keep hands, hair, clothing, etc. away from
all moving parts. Failure to do so can lead to serious
injury.
5.7 Check all accessories for firm seating.
5.8 If possible, close supply pressure and check the failsafe position.
5.10 Check stem boot for wear.
5.11 Check actuator for leaks. To do this, spray housing,
air connections and plug stem guide with leak spray
and check for any bubble formation.
5.12 Clean plug stem.
5.13 Check 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.

6 REMOVE AND INSTALL ACTUATOR
General Information
We recommend separating the actuator from
the valve during all repair work. However, many
maintenance and adjusting operations can be carried
out in an installed condition.
6.1 Remove series 4 actuator
(see Fig 1 + 2)
For series 2 actuator see 6.3
For actuators with spring-to-close, go to 6.1.1
For actuators with spring-to-open, go to 6.1.2
6.1.1 Shut off air supply.
WARNING: Depressurise the line to atmospheric
pressure and drain all fluids from the valve before
working on the actuator. Failure to do so can cause
serious injury.
6.1.2 Remove 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.
3.1.3 Using 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.
6.1.4 Loosen gland and clamp nuts.
6.1.5 Secure 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.
6.1.5 Remove actuator and remove at the same time
locknut, travel indicator disc, gland nut and clamp
nut.
3.2 Install 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.
6.2.1 Position actuator with clamp nut, gland nut, locknuts
and travel indicator disc on the valve.
6.2.2 Only 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.
6.2.3 Tighten clamp nut and gland nut.
6.2.4 Adjust 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.
6.2.5 After adjusting, secure the locknuts and the travel
indicator disc lying between them against actuator
stem and align the travel indicator on the yoke rod.
6.3 Remove series 2 actuator
(see Fig. 1a)
For series 4 actuator see 6.1
6.3.1 Shut off air supply.
WARNING: Depressurise the line to atmospheric
pressure and drain all fluids from the valve before
working on the actuator. Failure to do so can cause
serious injury.
6.3.2 Disconnect all tubing.
6.3.3 Remove 2 screws and remove coupling.
6.3.4 Remove yoke rod retaining nuts and lift actuator
assembly from the valve.
6.3.5 Remove coupling insert and it’s locknut from plug
stem.
CAUTION: Ensure that the plug assembly is not
rotated with the plug seated. This may cause
irreparable damage to the seating faces.
6.4 Install 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.
6.4.1 Screw coupling insert locknut and coupling insert as
far as possible onto plug stem.
6.4.2 Place the actuator assembly on the valve engaging the
yoke rod threads in the lower yoke plate and ensuring
the actuator faces in the correct direction.

6.4.3 Unscrew the coupling insert until the yoke rods are
raised from the lower yoke plate by around 2 mm.
CAUTION: Ensure that the plug assembly is not rotated
with the plug seated. This may cause irreparable
damage to the seating faces.
6.4.4 Refit the coupling, ensuring that the arrows, embossed
on the coupling halves, point upward towards the
actuator, and secure with 2 retaining screws.
6.4.5 Apply supply pressure resp. vent actuator to half stroke
and refit and tighten yoke rod retaining nuts (15).
6.4.6 Connect all tubing.
7 DISASSEMBLE AND ASSEMBLE VALVE
7.1 Disassemble Valve
(see Fig. 2)
7.1.1 Remove actuator according to section 3.
7.1.2 Remove housing bolts. Remove upper body with
plug.
7.1.3 Carefully press plug stem evenly out of the housing
upper part.
7.1.4 Insert two screwdrivers in outer groove of seat ring
and carefully lever seat ring out of lower body.
7.1.5 Check seating faces of seat ring and plug for damage.
Gasket surfaces must be clean and free of damage.
7.1.6 Press guides, packing and packing follower from be-
low using a drift (the drift must have a slightly larger
diameter than the plug stem).
CAUTION: To prevent damage to the plug, seat or plug
stem, follow the above instructions precisely.
7.1.7 If a seat surfaces need re-machining, seat and plug
seating surfaces must be reworked. The seat angle
on the plug is 30°, on the seat ring 25°. If the valve
is correctly assembled, lapping is not required.
CAUTION: When re-machining the plug, protect
plug stem from damage. The seat surface must be
concentric to the plug stem. When re-finishing the
seat, the seat surface must be concentric to the seat
outer diameter.
7.2 Assemble Valve
(see Fig. 2)
7.2.1 All worn or damaged parts must be replaced. Reus-
able parts must be clean. Expendable parts such
as gaskets, packing and O-rings should always be
replaced.
7.2.2 Insert seat ring in lower body, using new gaskets.
DANGER: It is most important to ensure that the
sealing rings are fitted and properly seated. The seat
and body halves are the primary metal-to-metal seal
so if the seal rings are omitted initial leak testing can
misleadingly indicate a leak-free operation. Without
sealing rings almost certainly seat leakage will occur
when the valve is in full operation.
7.2.3 Carefully guide plug stem through upper housing, to
avoid damage.
7.2.4 Position upper body on lower body carefully and absolutely upright, to avoid damage to the seat/plug.
7.2.5 Insert housing bolts and tighten alternating crosswise
finger-tight.
7.2.6 Insert lower stem bushing of the packing set in the
packing area, to give better guidance to the plug stem
when tightening the body halves.
7.2.7 Tighten body bolts alternating crosswise hand-tight,
while repeatedly moving the plug stem too and fro,
in order to check whether the plug is jammed in the
seat.
7.2.8 Using a torque wrench, gradually tighten the body
bolts to the prescribed torques (see following table),
alternating crosswise.
Note: While the body bolts are being tightened,
the body halves must always be parallel (see Fig. 3)
7.2.9 Replace packing by inserting packing rings one at a
time tapping each one down with a suitable bushing.
CAUTION: ensure that the gaps in the packing rings
are distibuted evenly around the circumferance in the
packing box (gaps not in line).
Note: different packings and fitting sequences are
shown in the spare parts list.
7.10 Insert packing follower. Fit gland nut for transport
purposes only. Gland nut to be fitted correctly and
tightened down when actuator is mounted.
