Electronic Expansion Valve for Air Conditioning System



Product Description:

Electronic expansion valves are widely used in air conditioning and refrigeration systems, as well as heat pumps. These valves offer automatic adjustment of the refrigerant flow rate, ensuring optimal system performance for faster cooling or heating, precise temperature control, and energy efficiency. In addition to these functions, they can also be applied for suction line pressure control. The bidirectional operation allows the valve to regulate refrigerant flow in both heating and cooling modes, making it highly versatile.
