Ing valve positioner metung yang mumunang accessory para kareng pneumatic actuators. Gagamitan de iti kayabe da reng pneumatic actuators para asundu ing pamagposisyon da reng balbula at alampasan ing epektu ning stem friction ampo ing e balansing pwersa ibat king medium, bang makasiguradung ing balbula makatuknang yang ustu agpang kareng signal ibat king controller.

Ing positioner dapat gamitan ya kareng makatuking sitwasyun:

Nung matas ya ing medium a pressure at maragul ing pamiyaliwa ning pressure.

nung ing sukad ning balbula maragul ya (DN > 100).

kareng matas a temperatura o mababang temperatura a control valves.

nung kailangan yang dagdagan ing bilis ning pamag-actuate ning control valve.

Nung gagamit kang standard a signal ampo mag-operate kang non-standard a spring ranges (spring a atyu king lual ning 20-100KPa).

nung gamitan ya para keng staged control.

Nung akit me ing reverse valve action (alimbawa, pamagbayu keng air-closed ampo air-opened).

Nung kailangan yang alilan ing flow characteristics ning valve (ing positioner cam malyari yang i-adjust).

nung ala yang spring actuator o piston actuator at kailangan ing proportional action.

Potang mag-operate kang pneumatic actuators kareng electrical signals, kailangan yang gamitan ing electrical-air valve positioner.

Solenoid Valve:

Nung ing sistema mangailangan yang program control o on-off control, gagamitan la reng solenoid valves. Potang mamili kang solenoid valve, bukud keng pamagkonsidera keng AC o DC power supply, voltage, ampo frequency, kailangan ing pansin keng functional a relasyun ning solenoid valve ampo ing control valve. Malyari yang maging normal a makabuklat o normal a makasara. nung kailangan yang dagdagan ing kapasidad ning solenoid valve para mabawas ing response time, adwa lang solenoid valve ing malyaring gamitan parallel o ing solenoid valve malyari yang gamitan bilang pilot valve kayabe ning maragul a kapasidad a pneumatic relay.

Pneumatic Relay:

Ing pneumatic relay metung yang power amplifier na malyaring mag transmit pneumatic signals kareng marayung lugal, a mamako keng lag a sangkan da reng makaba a signal pipelines. Keraklan magagamit ya pilatan da reng field transmitters ampo reng central control rooms para kareng instrumentu, o pilatan da reng controllers ampo reng field control valves. Atin ya namang gagawan a magpalakas o magpababa kareng signal.

Converter:

Deng converters makadake la kareng pneumatic-electric converters ampo electric-pneumatic converters. Ing karelang obra yapin ing mag convert kareng pneumatic ampo electric signals agpang keng metung a relasyun. Keraklan magagamit la nung mag-operate lang pneumatic actuators kareng electrical signals, mag-convert lang 0-10mA o 4-20mA electrical signals papunta kareng 0-100KPa pneumatic signals o vice versa, mag-convert lang 0-10mA o 4-20mA electrical signals.

Air Filter Regulator:

Deng air filter regulators ila reng accessories a gagamitan da reng industrial automation instruments. Ing karelang peka-obra yapin ing mag-filter ampo mag-purify keng compressed air ibat kareng air compressors ampo mag-stabilize keng pressure keng kailangan a ulaga. Malyari lang gamitan bilang gas sources ampo pressure stabilizing devices para kareng miyayaliwang pneumatic instruments, solenoid valves, cylinders, spray equipment, ampo mangalating pneumatic tools.

Self-locking Valve (Position Lock Valve):

Ing self-locking valve metung yang kasangkapan a gagamitan para a-maintain ing posisyun ning valve. Nung ing pneumatic control valve makaranas yang pangabagsak keng suplay ning angin, ing device ayni malyari neng pututan ing signal ning angin, at panatilyan ne ing pressure signal keng diaphragm chamber o cylinder keng estado bayu ya pangabagsak. Iti makasiguradung ing posisyun ning balbula manatili ya keng posisyun bayu ya mesira, a magsilbi keng sangkan ning pamagkandadu keng posisyun.

Valve Position Transmitter:

Nung ing control valve marayu ya keng control room at kailangan yang abalu ing posisyun ning valve a alang munta keng field, dapat yang i-install ing valve position transmitter. I-convert ne ing displacement ning valve opening mechanism keng electrical signal agpang keng metung a patakaran at padala ne keng control room. Ing signal ayni malyari yang maging patuloy a signal a magreflect keng nanu mang valve opening, o malyari yang ituring bilang inverse action ning valve positioner.

Travel Switch (Position Feedback Device):

Ing travel switch papakit nala deng adwang extreme a posisyun ning valve ampo sabay-sabay yang magpadala signal. Ing control room malyari neng abalu ing on-off status ning valve base keng signal ayni ampo gawa yang katumbas a paralan.
