Product Description:
Electronic expansion valves are specifically designed for use in air conditioning, refrigeration systems, and heat pumps. These valves allow for automatic adjustment of the refrigerant flow rate, ensuring optimal system performance for fast cooling or heating, precise temperature control, and energy efficiency. They can also be used for suction line pressure control. The bidirectional operation of these valves enables effective regulation of refrigerant flow in both heating and cooling modes.
Â
