Electronic expansion valve
What is an electronic expansion valve?
Electronic expansion valve is one of the most important devices in refrigeration. They have replaced thermostatic, dynamic and manual valves in the last few years. The electronic expansion valve is a mechanism to control the flow rate of refrigerant in refrigeration systems
The appropriate speed and high quality of this product have attracted the attention of facility engineers.
The location of electronic expansion valve in the refrigeration cycle
The electronic expansion valve is placed between the condenser and the evaporator in the boundary between the high and low pressure areas in cold stores. In other words, the expansion valve reduces the pressure of the refrigerant liquid in the refrigeration cycle.
Nowadays, electronic expansion valves are used for better feeding of the evaporator, reduction of average superheat, fast response, increase in stability, constant behavior, no need for periodic adjustments, more adaptation to changes in refrigeration load, and behavior in accordance with the operation of the control unit.
Carel electronic expansion valve – features
This product is capable of meeting the cooling needs of 2000 kilowatts in ventilation and refrigeration cycles. Electronic expansion valve works best in the whole flow control process, even in low flows.
- Reliability over time: The standard design process used for carel expansion valves includes lifetime testing. It also guarantees domestic and international standards. Compliance with these standards guarantees the maximum quality of the product and the production process, as well as a continuous commitment to improving the environment.
- Accurate control: electronic controllers, especially the optimization of air conditioning and refrigeration systems management, also guarantee energy savings. In addition, very accurate control is also guaranteed by the special shape of the moving elements and controls the flow in an Equal Percentage way. Also, the movement among the stroke is guaranteed by the use of stainless steel bearings and the use of high precision mechanical parts.
- Complete closure of the refrigerant flow path: the moving element is non-rotating despite the rotation of the motor. This is done using a high quality Teflon “water seal” .This sealing on the valve prevents any leakage. To improve the sealing of the expansion valve, a flexible steel spring is installed.
Kara Ravesh Saba company offers electronic expansion valves in the form of a kit (with driver) to the customers.
