PROBLEM TO BE SOLVED: To provide a fluid control valve capable of improving workability when installing and disassembling the fluid control valve, while checking progress of looseness of a screw, in the fluid control valve for fixing an actuator part to a body by screw-fastening.SOLUTION: A chemical valve is formed with through-holes 20H and 30H for inserting a bolt 60 into a cover, a cylinder, the body 30 and an installation plate 50. The cover is formed with a first recessed part communicating with the through-hole 20H and supporting-storing a head part of the bolt 60, and an opening of the first recessed part is blocked up and is brought into close contact in an elastically deformed state with the inner peripheral surface for forming the first recessed part and the head part of the bolt 60, and thereby, a head part side cap 40 is arranged for preventing the looseness of fastening force of the bolt 60. |
