electronic expansion valve controller

ecoVALVETRONIC electronic expansion valve controller

Controller regulates the flow of the refrigerant during compressor operation. ecoVALVETRONIC safeguards the compressor’s operation by maintaining the appropriate superheat value of the refrigerant, protecting against both low and high system pressures, power loss to the controller, and valve failure – the valve automatically closes in these instances.

controller functions

  • ability to handle both bipolar and unipolar expansion valves
  • independent setting of valve operation modes for heating, cooling, and defrosting
  • limitation of the valve’s regulation range for each operation mode
  • stabilization mode: a forced valve opening function during mode transitions
  • high resolution valve control and precise regulation of refrigerant superheat/subcooling through full-step, half-step, and quarter-step operation
  • full valve closure or positioning at any point in case of power loss
  • reading of digital inputs’ status and electronic detection of valve limit positions
  • hierarchy of protective algorithms and selection of refrigerants
  • capability to conduct valve motor tests
  • LED signaling for controller and valve operation status
  • additional alarm signaling through relays
  • detection of refrigerant leaks
  • recording of the number of steps executed by the valve and total durations of alarm states for the valve
