Model:GV-641
Electronic expansion valve for precision control (LEEV)
Electronic valve device to expand and evaporize liquid refrigerant by precision control of fluid quantity & temperature of air conditioner refrigerant through electronic control& multi-control
Strong points of Expansion Valve
1. Characteristics of detection part : applicable to temperature, pressure electric current adn others.
2. Possive to adjust Fluid Quantity Control freely by processing signal of MICOM.
3. High response characteristics.
4. Quick time cycle from opening to closing.
5. Applicable to wide range of refrigerating capacity variation.
6. Heat function of evaporator is enhanced due to correct and quick super heat control.
7. Exact reverse operation is possible.
- Function
Precision control (expansion→evaporation) of refrigerant flow as a core part of cooling cycle.
- Features
Multi-control is possible with electronic control device.
- Stepping motor type : Drive valve by rotational power of stepping motor
- Strong points
It can be utilized in many ways irrespective of type of refrigerant.
