The P5 Valve Control System is a valve positioning system from PMVwith a modular design concept.

The base unit of the system is the pneumatic positioner, used in eithersingle or double acting applications. P5 comes standard with built in

dampers, a 5 mm high gain spool valve assembly, gauge ports and anO-ring sealed housing. The housing utilizes a unique O-ring seal thatcan be adjusted to a sealed or drained position.

The modular design concept allows for easy addition of accessories

such as I/P converter and/or a feedback package, both which are

isolated from the basic pneumatic unit. These accessories can be factoryor field mounted.

Ease of calipation and maintenance are built into to the design with

easily accessible span and zero adjustment, and very simple parts

replacement.

PMV Positioner and feedback module storage

and handling procedures

PMV Positioners and feedback modules are precision instruments which should be storedand handled accordingly to avoid problems or damage.

Electropneumatic positioners/feedback modules contain electronic components whichcan be damaged by exposure to excessive water. Appropriate precautions should be takento protect units while in storage.

Warehouse storage

Stored in original PMV shipping containers, units should be stored in an environmentallycontrolled area, i.e. clean, cool (15-26°C, 60-80°F) and dry, out of direct sunlight or weatherexposure.

Field storage

Note: Once the air supply to the positioner is connected and turned on, internal air bleedwill prevent the ingress of moisture and protect the unit from corrosion. It is recommendedthat the air supply be left on at all times.

•If units are installed immediately, turn, and leave on, the air supply.

•If positioners must be stored outdoors, tighten all covers which may have loosened inshipment, make sure all open enclosure entry points are sealed.

Feedback modules should have cover tightened and conduits entries sealed. Positioners/Feedback modules should be wrapped and sealed air and watertight with desiccant insidethe plastic, units should be securely covered with an opaque cover and not exposed todirect sunlight, rain or snow.

Pneumatic positioners

Units should have all ports sealed and be protected from direct exposure to weather.For long term storage (>1 month) or overseas shipment units should be protected withplastic and desiccant.

Potential damage mechanism

When units are stored in hot, humid climates, the daily heating/cooling cycle will causeair to expand/contract and be drawn in and out of the positioner/feedback housing.Dependent on the local temperature variations, humidity and dew points

and time in storage condensation could occur and accumulate inside on the I/P Convertercausing erratic operation or failure due to water and corrosion. The potential forcondensation damage is especially high in southern climates and aggravated if units areexposed to direct sunlight.

For further assistance, please contact you nearest PMV office.

Storage Seal

P5/EP5 is supplied with all enclosure entry

points sealed.The seal is only a storage seal, not

to be used as seal when P5/EP5 is in operation.

If Storage Seal is removed or damaged, make

sure all open enclosure entry points are proper

resealed before further shipping or storage.

Use circular stickers marked I , S and OUT ,

supplied on Storage Seal or vapour proof tape.

The P5 operates on a force balance principal. Force is originated by thesignal pressure transmitted through a diaphragm on to the balancearm. The opposing force is achieved through the feedback spring andis proportional to the position of the lower arm. The lower arm posi-tion is determined by the position of the cam which is secured to thespindle and connected to the actuator shaft thus providing the feed-back from the actuator/valve. When these two forces are equal, thebalance arm and the spool in the pilot valve are in a neutral position-the complete unit is in a balanced position. Air is supplied to the pilotvalve through port S, and controls the air flow through ports C1 andC2

Assume an equilipium position.

An increased control pressure will deflect the diaphragm 1 down,compressing the feedback spring 3. The balance arm 2 moves the spool7 in the pilot valve 8 furnishing supply air to the actuator, while at thesame time air is exhausted from actuator and is vented to atmospherethrough the pilot valve and the OUT port .

With the increased supply air, the actuator rotates (or moves linearly)moving the positioner spindle 6. The spindle and cam 5 rotate, forcingthe lower arm 4 upwards compressing the feedback spring 3. Thismotion will continue until the two forces are equal and the unit is in anequilipium position.

Maximum supply pressure is 1 MPa (150 psi).

Supply air shall be clean, dry and free from oil, water, moisture, foreign parts anddepis.

The air shall be freeze-dried or similar to a dew point of at least 10°C (18°F) belowlowest expected ambient temperature.

A

Before making pneumatic connections to the positioner, it is recommended thatthe supply air lines are opened up and allowed to vent for 2-3 minutes to clear anydepis from the line. It is further recommended that a large paper bag is used tocollect any oil or humidity that may be present in the line during this purging,direct the air flow into the bag. Should exessive amounts of oil and/or humiditybe present at this stage, a review of the pneumatic system should be carried outand the problem corrected.

Poor air quality is one of the major causes of premature failure

of pneumatic equipment.

P5 mounts on to the actuator using either the ISO F05 holes 4 and a PMV ISOmounting kit or by using the optional mounting adaptor and screws 5 tomount P5 on to existing PMV mounting kits.

Proper alignment of the positioner spindle to the actuator shaft is veryimportant since improper alignment can cause excessive wear and friction tothe positioner.

The spindle/positioner shaft assembly allows for quick and simple spindlechanges. To ensure the proper connection, the spindle 3 has a spring clip 2that must be properly installed. A solid ”click" should be felt when assemblingthe two pieces insuring that the two flats 1 are engaged into the positionershaft groove.

The spindle can be removed, by inserting two screwdrivers under the twotapered surfaces of the spindle and bending carefully. When the spring clipreleases the spindle will eject.

The front cover of P5 is secured to the pneumatic unit with four

captured screws and sealed with an O-ring 1. The O-ring can be

looped over notches 2 in the front cover to allow for drainage.

There are eight locations on the front cover where the O-ring can be

looped. This O-ring system is common to the Pneumatic unit , I/P unit

and Feedback unit in the PMV Valve Control System P5. This unique

sealing system allows for complete sealing or draining of the units by

changing the position of the O-ring.

The indicator cover 3 is O-ring sealed and secured by a bayonet

coupling. The indicator cover is also used to secure the identification

cover 4.

To remove the indicator cover turn it slightly counterclockwise until it

loosens. Identification cover and O-ring 5 are now removable.

When installing indicator cover and identification cover make sure that

the O-ring is properly engaged.

P5/EP5 is when shipped from PMV pre-calipated for 90 ±0,5 deg rotation, (can also be30, 45 or 60 deg, see installed cam).

For most applications the valve closed positionis more critical than valve open position,most attention should be paid at valve closedposition. Always start calipation procedure byapplying 0 % input signal, then adjusting zero.P5/EP5 is calipated by turning thumb wheels 1& 4.

Arrows on arm 5 indicate turning direction ofthumb wheels.

“-“ = Decrease zero/span

Calipation procedure

Check cam seating, section 9 before startingcalipation procedure.

1. Apply 0 % input signal (0% = 20 kPa/3 psior 4 mA)

2. Wait for steady state.

3. Adjust zero by turning the silver (lower)thumb wheel 4 with finger or with screwdriver 7 from the outside.

4. Apply 100% input signal (100% = 100 kPa/15 psi or 20 mA)

5. Wait for steady state then memorize result.6. Apply 0% input signal.

7. Adjust span if necessary. This is done byfirst loosing screw 2, then turning theyellow (upper) thumb wheel 1 “+“ or “-“and finally tighten screw 2. Spring top mustnot be in contact with spring guide 3.8. Check zero and adjust if needed.

9. Repeat steps 2 to 8 until desired calipationis achieved.
