Application Industry
  1. Oil & Gas: Wellhead extraction, refinery processing and long-distance pipeline flow control in Zone 1/2 explosive hazardous areas.
  2. Petrochemical & Chemical: Reactor feeding, distillation column and corrosive medium pipeline process regulation.
  3. Power & Pulp Paper: Boiler feedwater regulation, steam pipeline control and pulp production line valve automation.

Common Problems & Solutions
  1. Valve no response to signal

    Solution: Verify 4-20mA input wiring and power supply; check air supply pressure and pneumatic line for leakage.

  2. Positioning deviation & inaccuracy

    Solution: Run one-button Quick-Cal auto-calibration; inspect valve stem linkage and position sensor for mechanical misalignment.

  3. Valve hunting / oscillation

    Solution: Switch gain setting to "HI FRIC" mode; filter compressed air supply to clean contamination inside the pneumatic relay.
