York S1-025-43225-000 4-Ton Thermal Expansion Valve 3/8" X 3/8" R-410A 31"Capillary Tube

The York S1-025-43225-000 is a thermal expansion valve (TXV) used to regulate refrigerant flow accurately in 4-ton air conditioning systems containing R-410A Refrigerant. This component is essentialfor the possible system operation and it has a 31” capillary tube and the input/output are 3/8”. The temperature of the evaporator determines the flow rate of refrigerant with help of a TXV. The valve gets information from the capillary with regard to the temperature of the evaporator to control the flow of the refrigerant.
