To provide a selector valve rationally incorporable into a gas-liquid separator, while simplifying a structure by reducing the number of part items for reducing the size and cost.
This selector valve has a first inlet 31 and a second inlet 32 integrally attached to the gas-liquid separator 10 used for a refrigerating cycle and introducing a refrigerant, an outlet 35 for selectively leading out the refrigerant from the first inlet 31 and the second inlet 32 into the gas-liquid separator 10, a first check valve 21 arranged between the first inlet 31 and the outlet 35, and a second check valve 22 arranged between the second inlet 32 and the outlet 35. The first check valve 21 and the second check valve 22 communicate the second inlet 32 with the outlet 35, and cut off the first inlet 31 and the outlet 35 when refrigerant pressure of the first inlet 31 is higher than refrigerant pressure of the second inlet 32, and communicate the first inlet 31 with the outlet 35, and cut off the second inlet 32 and the outlet 35 when the refrigerant pressure of the first inlet 31 is lower than the refrigerant pressure of the second inlet 32.
