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.
