The York S1-02545293000 Thermal Expansion Valve regulates the amount of refrigerant that enters the evaporator coil of HVAC systems that offers efficient heat exchange and ensures the stability of the system. It contains 3/8" and 5/8" ODF connections and is directly mounted at the evaporator inlet and responds to changes in temperature and pressure in order to provide the optimum superheat. The valve assists in sustaining the same cooling performance through preventing evaporator flooding or starvation owing to the regulation of refrigerant delivery, which assists in safeguarding the compressor.
