Description
The Trane VAL18907 Reversing Valve is used to change the direction of refrigerant flow enabling transition between heating and cooling modes in HVAC systems. It plays a central role in heat pump operation by allowing a single system to perform both functions through controlled flow redirection. It operates through an internal valve mechanism that shifts refrigerant pathways based on control signals allowing the cycle to reverse as required. Positioned within the sealed refrigerant circuit, it interfaces with compressors and coils to manage flow direction and support proper system operation.
