4 way reversing valve

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

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.

1.Exteral leakage test pressure: 3.0 Mpa

2.Max.operating pressure: 3.0 Mpa

3.Water test pressure: With water pressure 4.4Mpa

4.Burst pressure: 14.7Mpa

5.Ambient Temperature: Power on -20 to +50°C

6.Relative Humidity: Less than95%RH

7.Fluid permission temperature: -20 to +120°C
