Amana-Goodman XVB18-36C Expansion Valve Kit

The Amana-Goodman XVB18-36C Expansion Valve Kit is a refrigerant metering package that controls the flow of liquid refrigerant entering the evaporator coil by reducing its pressure at a calibrated rate, which causes the refrigerant to expand and absorb heat from the surrounding airstream. The thermostatic expansion valve within the kit responds to superheat conditions at the evaporator outlet, continuously adjusting the flow rate to match the coil's real-time heat load rather than operating at a fixed setting. Within HVAC systems, this kit fits into the liquid line circuit of compatible cooling equipment, regulating refrigerant feed to the evaporator and preventing floodback.
