Description
The York S1-02213719000 Thermal Expansion Valve is a metering component used to control the flow of refrigerant in HVAC systems. It is rated at 8 tons, has 1/2-inch and 7/8-inch outside diameter connections, and a 91 PSIG pressure setting to meter the liquid refrigerant into the evaporator depending upon load conditions to maximize heat absorption. This valve is used in commercial air conditioners and heat pumps to detect variations in superheat and vary the flow. It is installed in the liquid line between the condenser and evaporator coil, and it is used as a core system component.
