A pressure chamber partitioned by a piston that drives the poppet valve body, a seat spring that brings the poppet valve body into contact with the valve seat, and a drive unit assembled to the valve body, supplying and discharging water to and from the pressure chamber. In a fluid control valve in which a poppet valve element opens and closes a valve seat depending on the acting force of the pilot fluid and the biasing force of the seat spring, the poppet valve is provided with a valve that penetrates the wall of the drive section and connects its tip to the piston. a fixed assembly bolt is provided, the assembly bolt having a head having a gap with the wall surface when the drive section is assembled to the valve body;
A fluid control valve characterized in that the head has a length such that the head comes into contact with a wall surface to prevent the piston from jumping out when separated from the valve body.
