Description
The York S1-025-47939-000 AC Coil EEV is an electromechanical actuator used in HVAC systems such as split air conditioners, heat pumps, and rooftop cooling units, regulating refrigerant flow through an electronic expansion valve by translating electrical input into precise valve movement. A twisted coil generates a magnetic field that shifts the valve needle according to cooling demand and pressure variation. It is fitted onto the valve body during refrigeration line assembly or replacement. This process maintains accurate refrigerant metering, supports steady heat exchange, and reduces fluctuations in cooling output.
