Description
The Trane VAL19561 Reversing Valve is a refrigerant flow element that switches the direction of fluid movement to enable heating and cooling operation within heat pump systems. It operates through an internal sliding spool mechanism that shifts position based on system pressure and control signals, redirecting refrigerant between indoor and outdoor coils to change operating mode. In HVAC systems, it is used in heat pumps and split systems to alternate between heating and cooling operations. It is connected within the cooling circuit between coil assemblies and supports efficient mode switching, stable thermal performance, and reliable system operation.
