York S1-022-12986-000 Thermal Expansion Valve (TXV) R-410A

The York S1-022-12986-000 Thermal Expansion Valve (TXV) is a precision component used in HVAC systems utilizing R-410A refrigerant. It serves as a control element and directly measures the amount of liquid refrigerant in the evaporator given the overall condition of the system. The TXV features a component that is sensitive to the temperature of the evaporator. Due to varying evaporator load, the TXV modifies the refrigerant flow rate to provide maximum system performance and efficiency. This dynamic control minimizes situations where the refrigerant is overfed leading to liquid slugging and causing harm to the compressor and also situations where the refrigerant is underfed and therefore leading to low cooling capacity.
