4-way reversing valve is a component to switch the system between cooling and heating modes.

By switching the flow of refrigerant, the air-conditioner can incorporate the functions of cooling in summer and heating in winter together.

The 4-way reversing valve consists of main valve, pilot valve, and solenoid coil.
