York S1-025-43245-000 3Ton Thermal Expansion Valve(Txv) 30" Capillary 3/8" X 5/8" ODF

The York S1-025-43245-000 3/8" x 5/8" ODF Thermal Expansion Valve (TXV) is a high precision component that improves the efficiency of HVAC systems. This TXV has inlet and outlet connections with dimensions of 3/8" x 5/8" and a capillary tube length of 30", which is designed to handle up to 3 tons of cooling capacity and is therefore suitable for medium sized air conditioning systems. The refrigerant flow of this thermal expansion valve is regulated to the evaporator coil to provide the cooling performance possible. The refrigerant pressure and temperature changes sensed by the capillary tube cause it to respond by adjusting the flow of the refrigerant. This precise control keeps the pressure within the evaporator just right and helps prevent troubles, like refrigerant flooding or starvation that can damage efficiency.
