Application Industry
Oil & Gas: Deployed in crude oil/gas gathering pipelines, refinery separation units and tank farm systems, certified for safe operation in explosive hazardous zones.
Chemical & Petrochemical: Applied for flow regulation of corrosive and neutral process media in reactor feeding, fractionation and circulating piping systems.
Power & Water Treatment: Used in steam, circulating water and water supply systems of thermal power plants and municipal water treatment projects.
Common Problems & Solutions
No pneumatic output from positioner: Verify stable 4-20mA input signal and supply air pressure; clean the air filter regulator to eliminate air path blockage.
Valve position deviation & low accuracy: Run full auto-calibration via HART communicator; check for actuator air leakage and valve stem jamming.
HART communication failure: Check signal wiring polarity and loop power supply; isolate signal cables from strong electromagnetic interference sources.
