A valve directs fluid flow received from a device to one of a heater and a cooler. The valve includes a spool movably disposed in the housing between a first, second, and third position. An actuator is in fluid communication with the fluid. The actuator includes a smart material that deactivates when the fluid temperature is no greater than a first temperature, partially activated when the fluid temperature is greater than the first temperature, and fully activated when the fluid temperature is at least equal to a second temperature. The spool moves to the first position when deactivated and fluid flows from the cavity, to the heater. The spool moves to the second position when partially activated to prevent fluid from flowing to each of the heater and the cooler. The spool moves to the third position when fully activated and fluid flows from the cavity, to the cooler. 种阀，其引导从装置接收的流体流动到加热器和冷却器中之。阀包括阀芯，其在第、第二和第三位置之间可移动地设置壳体中。致动器与流体连通至所述流体。致动器包括智能材料，其在流体温度不大于第温度时不启用，在流体温度大于第温度时部分地启用，且在流体温度至少等于第二温度时完全启用。当不启用时，阀芯
