1 USING 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 bulletinpriortoinstalling,operatingorperformingany maintenance.
DANGER: InmostcasesKämmervalvesandactuators aredesignedforspecificapplications(e.g.withregard 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 apparent.
DANGER: indicates that death, severe personal injury and/orsubstantialpropertydamagewilloccurifproper precautions are not taken.
WARNING:indicatesthatdeath,severepersonalinjury STOP! and/orsubstantialpropertydamagecanoccurifproper
precautions are not taken.
CAUTION: indicates that minor personal injury and/or 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 theproductitself)isessential,inordertoavoidfaults, whichinthemselvesmightdirectlyorindirectlycause 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 andisfreefromharmfulsubstances.Insuchcasespay 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,havebeenauthorisedbythoseresponsible for the safety of the plant to perform the necessary work and who can recognise and avoid possible dangers.
1.5Installation
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.

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 valvetherearemovingparts.ToavoidinjuryFlowserve 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 STOP! acertificatewhichconfirmsthattheproducthasbeen decontaminated and is clean. Kämmer will not accept deliveriesifacertificatehasnotbeenprovided(aform
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 flangefacestopreventtheingressofforeignmaterials. 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 theyprovideinformationforeverypossibleexampleof installation,operationormaintenance.Thismeansthat theinstructionsnormallyincludeonlythedirectionsto 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.
2.1Eachdeliveryincludesapackingslip.Whenunpacking, 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: Ifslingsareused,beawarethatthecentre

2.3Report transport damage to the carrier immediately.
2.4In case of discrepancies, contact your nearest FLOWSERVE sales office.
3INSTALLATION
3.1Clean tubing prior to installing.
3.2If possible, install the valve in an upright position (actuator on top), to ease maintenance. An upright installationpositionisimportantwithlow-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
3.3Make sure that sufficient overhead clearance above the actuator is maintained, to allow for disassembly of plug from the valve body (see following table).

3.4Afterinstalling,checkdirectionofflowagain.Thediretion 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:
Kammer ControlValves
5.2Check bellows gasket and test connection - if present - for external leaks.
5.3Check valve for damage caused by corrosive residues or corrosive vapours.
5.4Clean valves and repaint as necessary.
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).

NOTE: An excessively tightened gland nut can cause excessivepackingwearandcanhinderthefreemovement of the plug stem.
4.5Check fail-safe position. To do this, close supply pressure and observe whether the valve opens or closes as defined.
4.6Afteruseatfluctuatingtemperatures,re-tightenallbolt 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).
Warning: To prevent a buildup of electrostatic charge STOP! clean the actuator/valve with a damp cloth only.
5.5Check gland nut for correct torque (see table 1)..
NOTE: An excessively tightened gland nut can cause excessivepackingwearandcanhinderthefreemovement of the plug stem.
5.6If 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:Keephands,hair,clothing,etc.awayfrom STOP! all moving parts. Failure to do so can lead to serious
injury.
5.7Check all accessories for firm seating.
5.8If possible, close supply pressure and check the failsafe position.
5.10Check stem boot for wear.
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 maintenancepleasecontactyournearestFLOWSERVE office.
DANGER: On actuators with aluminium cases the actuatorspringsmustberenewedwithoriginalspare parts every 10 years or after 50.000 operating hours which ever occurs first.
