The General
This is a motor activated expansion valve for HVAC(Heating Ventilating & Air-Conditioning) system such as Heat-pump, refrigerator or Automobile air-conditioning system.
Especially, Permanent Magnet type stepping motor controls the Optimum refrigerant expansion pressure value & flow rate.
Features
- Apply permanent magnet type stepping motor in house to driving valve.
- Electronic driving frequency controls the flow rate very precisely up to 500 pulse
- Reverse valve enables to apply every HVAC application circuit.
- Capable of applying to all refrigerant types.
- Capable of controlling a flow rate proportionally and quick-opening at special point.
- Light weight and compact size.
