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 a valve seat, and a drive unit assembled to the valve body, which supplies and discharges 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 drive section is placed between the piston and the valve body when assembled to the valve body. A fluid control valve characterized in that the fluid control valve is sub-assembled with a retaining ring that has a gap and that locks onto the piston when separated from the valve body.
