Application Industry
- Oil & Gas: Wellhead extraction, refinery processing and long-distance pipeline flow control in Zone 1/2 explosive hazardous areas.
- Petrochemical & Chemical: Reactor feeding, distillation column and corrosive medium pipeline process regulation.
- Power & Pulp Paper: Boiler feedwater regulation, steam pipeline control and pulp production line valve automation.
Common Problems & Solutions
- Valve no response to signal
Solution: Verify 4-20mA input wiring and power supply; check air supply pressure and pneumatic line for leakage.
- Positioning deviation & inaccuracy
Solution: Run one-button Quick-Cal auto-calibration; inspect valve stem linkage and position sensor for mechanical misalignment.
- Valve hunting / oscillation
Solution: Switch gain setting to "HI FRIC" mode; filter compressed air supply to clean contamination inside the pneumatic relay.
