Zusammenfassung:	To easily attach and detach an attachment bolt without operating an actuator.SOLUTION: A fluid control valve 1 comprises a valve body 3 having an internal seal face 33, a diaphragm 4 abutting on or separating from the internal seal face 33, an actuator 2 connected to the diaphragm 4, and incorporating a compression spring 26 for energizing the diaphragm 4 to the valve body 3 side therein, and a plurality of attachment bolts 5 for attaching the valve body 3 to the actuator 2. A manually-operated stopper mechanism 7 for limiting the elongation of the compression spring 26 when attaching and detaching the attachment bolts 5 is arranged at the fluid control valve 1.SELECTED DRAWING: Figure 3 【課題】アクチュエータを動作させなくても取付ボルトの着脱を容易に行えるようにすること。【解決手段】流体制御弁１は、内部シール面３３を備えるバルブボディ３と、内部シール面３３に当接または離間するダイアフラム４と、ダイアフラム４と連結され、ダイアフラム４をバルブボディ３側に付勢する圧縮バネ２６を内蔵するアクチュエータ２と、バルブボディ３をアクチュエータ２に取り付ける複数の取付ボルト５と、を備える。この流体制御バルブ１に、手動操作可能であって、取付ボルト５を脱着する場合に圧縮バネ２６の伸張を制限するストッパ機構７を設ける。【選択図】図３
