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, dang-erous, 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.

1.6 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:
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 and 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.
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:
STOP!
tre of gravity of the valve may be above the lifting
If slings are used, be aware that the cen-
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 low­temperature 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
3.3 Make sure that sufficient overhead clearance above the actuator is maintained, to allow for disassembly of plug from the valve body.
3.4 After installing, check direction of flow again. The direction 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. Series 4 actuators and positioners are suitable for max. 4.2 bar (60 psi) supply pressure. If the supply pressure 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.
STOP!
WARNING:
Prevent other items of equipment from
making mechanical contact with the actuator housing.
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 valve/actuator and repaint as necessary. Warning:
STOP!
clean the actuator/valve with a damp cloth only.
5.5 Check gland nut for correct torque (see table 1).

NOTE: With graphite packing, irregular movement of the plug stem is normal.
STOP!
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.
5.9 Check stem boot for wear.
5.10 Check actuator for leaks. To do this, spray housing, air connections and plug stem guide with leak spray and check for any bubble formation.
5.11 Clean plug stem.
5.12 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.
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.
