York S1-VLV-012B-410 1-Ton Thermal Expansion Valve R-410A 3/8 X 1/2"ODF

The York S1-VLV-012B-410 is a thermal expansion valve (TXV) for use in HVAC systems that have a 1-ton capacity. This part provides for control of refrigerant flow into the evaporator with R-410A refrigerant. The unit has 3/8” and 1/2” ODF connections which makes it compatible with many HVAC systems. The refrigerant metering device used in the system is a TXV. It measures the temperature of the evaporator and in response alters the flow rate of the coolant. Eliminating liquid refrigerant from entering the compressor and enhancing energy efficiency, ensures that the system operates to the maximum capacity. The TXV also ensures that comfort levels are well regulated and that the cooling or heating ability is improved by regulating the amount of refrigerant.
