1.1 UsingThe following instructions are designedto assist in unpacking, installing andperforming maintenance as required onFLOWSERVE products. Product usersand maintenance personnel shouldthoroughly review this bulletin prior toinstalling, operating or performing anymaintenance.
1. General information
1.2 Terms concerning safetyThe safety terms DANGER,WARNING, CAUTION and NOTEare used in these instructions tohighlight particular dangers and/or to provide additional informa-tion on aspects that may not bereadily apparent.
DANGER: indicates that death,severe personal injury and/orsubstantial property damage willoccur if proper precautions are nottaken.
WARNING: indicates that death,severe personal injury and/orsubstantial property damage canoccur if proper precautions are nottaken.
CAUTION: indicates that minorpersonal injury and/or propertydamage can occur if properprecautions are not taken.
In most cases FLOWSERVE valves,actuators and accessories are designedfor specific applications (e.g. with regardto medium, pressure, temperature). Forthis reason they should not be used inother applications without first contactingthe manufacturer.
NOTE: indicates and providesadditional technical information,which may not be very obviouseven to qualified personnel.
Compliance with other, not particularlyemphasised notes, with regard to trans-port, assembly, operationandmaintenance and with regard to technicaldocumentation (e.g. in the operatinginstruction, product documentation or onthe product itself) is essential, in orderto avoid faults, which in themselves mightdirectly or indirectly cause severe per-sonal injury or property damage.

1.3 Protective clothingFLOWSERVE products are often usedin problematic applications (e.g.extremely high pressures, dangerous,toxic or corrosive mediums). In particularvalves with bellows seals point to suchapplications. When performing service,inspection or repair operations alwaysensure, that the valve and actuator aredepressurised and that the valve hasbeen cleaned and is free from harmfulsubstances. In such cases pay particularattention to personal protection(protective clothing, gloves, glasses etc.).
1.4 Qualified personnelQualified personnel are people who, onaccount of their training, experience andinstruction and their knowledge of rele-vant standards, specifications, accidentprevention regulations and operatingconditions, have been authorised bythose responsible for the safety of theplant to perform the necessary work andwho can recognise and avoid possibledangers.
1.5 InstallationDANGER: Before installationcheck the order-no, serial-no. and/or the tag-no. to ensure that thevalve/actuator is correct for theintended application.Do not insulate extensions that areprovided for hot or cold services.
Pipelines must be correctlyaligned to ensure that the valve isnot fitted under tension.
Fire protection must be providedby the user.
1.6 Spare partsUse only FLOWSERVE original spareparts. FLOWSERVE cannot acceptresponsibility for any damages that occurfrom using spare parts or fasteningmaterials from other manufactures. IfFLOWSERVE products (especiallysealing materials) have been on store forlonger periods check these for corrosionor deterioration before using theseproducts. Fire protection forFLOWSERVE products must beprovided by the end user.
1.7 Service / repairTo avoid possible injury to personnel ordamage to products, safety terms mustbe strictly adhered to. Modifying thisproduct, substituting nonfactory parts, orusing maintenance procedures otherthan outlined in this instruction coulddrastically affect performance and behazardous to personnel and equipment,and may void existing warranties.Between actuator and valve there aremoving parts. To avoid injuryFLOWSERVE provides pinch-point-protection in the form of cover plates,especially where side-mounted position-ers are fitted. If these plates are remo-ved for inspection, service or repair spe-cial attention is required. After completingwork the cover plates must be refitted.
Apart from the operating instructions andthe obligatory accident preventiondirectives valid in the country of use, allrecognised regulations for safety andgood engineering practices must befollowed.

WARNING:Before products are returned toFLOWSERVE for repair or serviceFLOWSERVE must be providedwith a certificate which confirmsthat the product has beendecontaminated and is clean.FLOWSERVE will not acceptdeliveries if a certificate has notbeen provided (a form can beobtained from FLOWSERVE).
1.8 StorageIn most cases FLOWSERVE productsare manufactured from stainless steel.Products not manufactured fromstainless steel are provided with anepoxy resin coating. This means thatFLOWSERVE products are wellprotected from corrosion. NeverthelessFLOWSERVE products must be storedadequately in a clean, dry environment.Plastic caps are fitted to protect theflange faces to prevent the ingress of fo-reign materials. If the positioner must be
stored outdoors, it is important that all thecover screws are tightened and that allconnections and ports are properly sea-led. Replace shipping plugs with properplugs and do not leave ports open andfacing upwards.
1.9 Valve and actuatorvariationsThese instructions cannot claim to coverall details of all possible productvariations, nor in particular can they prov-ide information for every possibleexample of installation, operation ormaintenance. This means that theinstructions normally include only thedirections to be followed by qualified per-sonal where the product is being usedfor is defined purpose. If there are anyuncertainties in this respect particularlyin the event of missing product-relatedinformation, clarification must be obtainedvia the appropriate FLOWSERVE salesoffice.
2. Unpacking
Each delivery includes a packing slip.When unpacking, check all deliveredvalves and accessories using thispacking slip.
Report transport damage to the carrierimmediately.
In case of discrepancies, contact yournearest FLOWSERVE location.

where the supply pressure is higher thanthe maximum actuator pressure rating asupply regulator is required to lower thepressure to the actuator’s maximum ra-ting (not to be confused with operatingrange). A coalescing air filter isrecommended for all applications due tothe close tolerances in the positioner.
PMV D20 positioner accessories:Optional analog feedback system as wellas limit switch unit and a directlyattachable double acting module.
NOTE: The air supply must conform toISA 7.0.01 or IEC 770 (a dew point atleast 10°C/18°F below ambient tempera-ture, particle size below five microns –one micron recommended – and oil con-tent not to exceed one part per million).

The PMV D20 is a two-wire looppowered, 4-20 mA input digital valvepositioner.
The PMV D20 positioner controlsactuators with linear and rotarymountings.
The PMV D20 is completely powered bythe 4-20 mA input signal. The minimuminput signal required to function is 3,6mA. As an option the D20 can beequipped with HART protocol to allowbidirectional communication.
Since the positioner is insensitive tosupply pressure changes and can handlesupply pressures from 1,5 to 6 barg (22to 105 psig), a supply regulator is usuallynot required; however, in applications

The PMV D20 positioner is a digital posi-tioner with various options. The positio-ner consists of three main modules:
1. The microprocessor-based electroniccontrol module includes direct local userinterface switches
2. The piezo valve-based electro-pneumatic converter module
3. The infinite resolution valve positionsensor.
The basic positioner operation is bestunderstood by referring to figure 1. Thecomplete control circuit is powered by thetwo-wire, 4-20 mA command signal. Theanalog 4-20 mA command is passed tothe microprocessor, where it is comparedto the measured valve stem position. Thecontrol algorithm in the processorperforms control calculations andproduces an output command to thepiezo valve, which drives the pneumatic
amplifier. The position of the pilot valvein the pneumatic amplifier is measuredand relayed to the inner loop controlcircuit. This two-stage control providesfor more responsive and tighter controlthan is possible with a single stagecontrol algorithm. The pneumaticamplifier controls the airflow to theactuator. The change of pressure andvolume of the air in the actuator causesthe valve to stroke. As the valveapproaches the desired position, thedifference between the commanded po-sition and the measured positionbecomes smaller and the output to thepiezo is decreased. This, in turn, causesthe pilot valve to close and the resultingflow to decrease, which slows theactuator movement as it approaches, thenew commanded position. When thevalve actuator is at the desired position.the pneumatic amplifier output is held atzero, which holds the valve in a cons-tant position.

7.1 GeneralBefore starting installation, inspect the di-gital positioner for any transit damages.The PMV D20 positioner is installed with amounting kit (according to NAMURspecification) to the left-hand actuator sup-port rod.
Generally, the unit can be installed in anymounting position. The stroke feed-backis realized by a follower arm and stemclamps.
The mounting of rod actuators (accordingto NAMUR) is described in Figure 3.
For the two mounting possibilities of castyoke actuators (according to NAMUR, lEC534 part 6) refer to Figure 5.
After installation, ensure all screwconnections are tightened correctly andall moving parts are free from excessivefriction.
7. Mounting and installation
NOTE!All products that are covered by an ATEX Certification number ending with an“X”, special care must be taken when cleaning the surface of the product.“The enclosure must be cleaned with a damp cloth due to static electricity forplastic windows/surfaces”
For securing covers and lids, it’s important to use the correct torque:
Product Size (screw) Torque Nm D20 M4 0,65 Nm +/- 15%
Covers (thread on) for D20EX, tighten fully and secure.

7.3 Mounting
N.B. If the positioner is installed in ahazardous environment, it must beof a type approved for this purpose.
The PMV D3 positioner, all versions, hasan ISO F05 footprint, A. The holes areused to attach the PMV D3 to themounting bracket B. Please contact PMVor your local distributor representativewith actuator specifics for the propermounting bracket and hardware.
The spindle adapter C can be changedto suit the actuator in question.
Remove the existing adapter using twoscrewdrivers. Check that the spring ringon the positioner spindle is undamagedand fit the new adapter. Alternative, pressout pin and remove adapter.
It is important that the positioner’s spindleand the arms, that transfer the actuatormovements, are correctly mounted. Anytension between these parts can causeincorrect operation and abnormal wear.

Mounting of the PMV D20 positioneron a linear pneumatic actuator(NAMUR / IEC 534 part 6)(See Figure 1)
The mounting of a rod actuator kit(according to IEC 534 part 6) is describedin an example by using the followingequipment:Valve: Standard globe valve orequivalentActuator: Single-acting pneumaticactuatorPositioner: PMV D20 with NAMURmounting kit.
Pre-assembly: Valve with actuator (valvestroke is matched with the actuatorstroke).
For mounting, proceed as follows:
Mounting the Follower Arm (Figures 1and 2)1. Unscrew the lock nut for the followerarm attachment.2. Place the follower arm on the shaft atthe back of the positioner and fasten it withthe lock nut. The follower pin should pointback from the positioner.
CAUTION: Maximum torque0,25 Nm (0,18 ft-lbs).
Mounting the stem clamp bracket andtake-off arm (Figure 1)1. Attach the stem clamp bracket to thestem clamp and fasten it with two hexa-gon socket screws and lock washers.
2. Attach the take off arm to the stem clampbracket and fasten it with a hexagonsocket capscrew and a washer. Ensurethe take-off arm slot is centered.

Mounting the positioner (Figure 1)1. Adjust the actuator to mid-stroke.
2. Pre-assemble the mounting bracket onthe left actuator leg hand-tight with two U-bolts, nuts and lockwashers.
3. Attach the positioner to the pre-assembled mounting bracket and fastenit with two hexagon head screws and twolock washers. Check that the follower pinis inserted in the slot of the take-off armand the follower arm is positioned at a rightangle to the outer edge of the positioner.
4. Tighten all screws and nuts.
NOTE: A slight unsymmetricalmounting increases the linearitydeviation but does not affect theperformance of the device.
Figure 3. Basic Adjustment for a Linear Pneumatic Actuator
Depending on the actuator sizeand stroke it may be necessary toflip the take-off arm (Figure 3) by180° and attach it to the oppositeside of the stem clamp bracket.

Follower pin adjustment (Figure 3)The positioner follower pin must beadjusted to match the valve stroke in thefollowing manner:
1. Adjust the follower pin (STROKE + 10mm) as indicated on the follower arm’sembossed scale (Figure 2).
2. Exhaust the actuator.
3. Loosen the follower pin and shift it alongthe follower arm until the control markingon the feedback gear (Figure 4) is hori-zontal (points to the center of the feed-back potentiometer). Fasten the followerpin in this position.
4. Adjust the actuator to full stroke andcheck the follower pin adjustment thesame way as described in step 3. As theactuator strokes, the rotation of the feed-back gear should be between the innercontrol markings. If the length of rotationis outside the control markings, adjust thefollower pin farther out on the feedbacklever to reduce the angle of rotation.
NOTE: Stroke the actuator carefully andensure the follower arm does notinterfere with valve parts, actuator orpositioner. Do not adjust the follower pintoo near to the slot end of the take-offarm.
The minimum lateral distance should beapproximately 5 mm (0,2 inches) to pre-vent bending of the feed-backmechanisim.

After mounting has been completed,tube the positioner to the actuator usingthe appropriate compression fittingconnectors:
Air connections: 1/4” NPT (standard airconnection).
Auxiliary power: Pressurized air orpermissible gases, free of moisture anddust in according with IEC 770 or ISA7.0.01.
Pressure range: 1,5 – 6 bar (30 – 90 psi).
For connecting the air piping, thefollowing notes should be observed:
1. The positioner passageways areequipped with filters, which remove me-dium and coarse size dirt from thepressurized air. If necessary, they areeasily accessible for cleaning.
Mounting the positioner (Figure 6)Place the positioner (1) onto themounting block (2) of the actuator usingfour screws (3) Ensure the coupler fits

2. Supply air should meet IEC 770 or ISA7.0.01 requirements. A coalescing filtershould be installed in front of the supplyair connection (Figure 8). Now connectthe air supply to the filter, which isconnected to the PMV D20 positioner.
3. With a maximum supply pressure of 6bar (102 psi) a regulator is not required.
4. With an operating pressure of morethan 6 bar (90 psi), a reducing regulatoris required.
The flow capacity of the regulator mustbe larger than the air consumption of thepositioner (7 Nm3 /h @ 6 bar / 4,12 scfm@ 90 psi).
5. Connect the outlet connector (Figure7) of the positioner with tubing, indepen-dent of the action (direct or reverse).

Connect the 4-20 mA current source toterminals +1 and -2, see connection ta-ble.
9.1 Grounding screwThe grounding screw, located inside thepositioner cover, should be used to prov-ide the unit with an adequate and reliableearth ground reference. This groundshould be tied to the same ground as theelectrical conduit. Additionally, theelectrical conduit should be earthgrounded at both ends of its run. Thegrounded scrrew must not be used totermingate signal shield wires.
Electrical connections: signal cablewith cable passage (1/2” NPT, or M20 x1,5) to terminals 2 x 2,5 mm.
Input signal: 4 – 20 mA
NOTE: Observe the minimumrequirements of voltage and equivalentelectrical load:
8 VDC at 20 mA non HART version9,4 VDC at 20 mA HART version
The performance is ensured only for aminimum input current of 3,6 mA.
For wiring, the following notes should beobserved:
NOTE: The input loop current signal tothe PMV D20 should be in shielded cable.Shields must be tied to a ground at onlyone end of the cable to provide a placefor environmental electrical noise to beremoved from the cable. In general,shield wire should be connected at thesource. (Figure 7).

The PMV D20 digital positioner has beendesigned to operate correctly inelectromagnetic (EM) fields found intypical industrial environments. Careshould be taken to prevent the positio-ner from being used in environments withexcessively high EM field strengths(greater than 10 V/m). Portable EMdevices such as hand-held two-way ra-dios should not be used within 30 cm ofthe device.
Ensure proper wiring and shieldingtechniques of the control lines, and routecontrol lines away from electro-magneticsources that may cause unwanted noise.
An electromagnetic line filter can be usedto further eliminate noise.
In the event of a severe electrostatic dis-charge near the positioner, the deviceshould be inspected to ensure correctoperability. It may be necessary torecalibrate the PMV D20 positioner torestore operation.

Example: DCS Compliance Voltage = 19 VRbarrier = 300Ω
Rwire
= 25Ω
CURRENTMAX
= 20 mA
Voltage = 19 V – 0.020 A(300Ω + 25Ω) = 12.5 V
This system will support the PMV D20, asthe voltage 12.5 V is greater than the required8 VDC for non-HART and 9.4 VDC for HART.
9.3 Compliance voltageOutput compliance voltage refers to thevoltage limit the current source can prov-ide. A current loop system consists of thecurrent source, wiring resistance, barrierresistance (if present), and the PMV D20impedance.
The PMV D20 requires that the currentloop system allow for a 8.0 - 9.4 VDCdrop across the positioner at maximumloop current.
CAUTION: Never connect avoltage source directly across thepositioner terminals. This couldcause permanent circuit boarddamage.
In order to determine if the loop will sup-port the PMV D20, perform the followingcalculation:
Figure 9. Compliance voltage
Voltage = Compliance Voltage(@CurrentMAX
)
– CurrentMAX
(Rbarrier
+ Rwire
)
To support the PMV D20 the calculatedvoltage must be greater than 9.4 VDC forD20 HART and 8 VDC for non-HART.
