PROBLEM TO BE SOLVED: To provide a fluid control valve capable of controlling a flow rate of a fluid with good responsibility in a wide flow rate range according to rise of a fluid pressure.SOLUTION: A fluid control valve includes: a device body 4 that is provided in a circulation flow passage 2 circulating a fluid through an internal combustion engine E and a heat exchanger H; an inflow passage 5 that flows the fluid into the device body 4; an outflow passage 6 that flows out the fluid from the device body 4; a valve body 7 that adjusts a flow rate of the fluid; a valve seat 8 that is provided so as to make a contact part 8a with the valve body 7 face to the downstream side of a fluid circulation direction; a solenoid 9 that contacts the valve body 7 with the valve seat 8 by electrification; and a spring mechanism 10 that holds an equilibrium state at a position where the valve body 7 is separated from the valve seat 8 by a predetermined distance L, when the solenoid 9 is in a non-electrification state and there is no flow of the fluid. |
