Zusammenfassung:	To realize appropriate operation of a valve in a valve drive system.SOLUTION: A valve drive system S1 comprises: a gas operating valve 71 which forms a flow path for a fluid F1 when gas G1 having a predetermined pressure or higher is supplied to a first pipe 106; first gas supply sources 42, 44, 50, 60 that generate gas G1 having a predetermined pressure or higher; a rupture disk 30 that forms a path to supply the gas G1 flowing from the first gas supply sources 42, 44, 50, 60 to a second pipe 104 when it is broken; a switching valve 21 that communicates the first pipe 106 with the second pipe 104 when the gas G1 is supplied to the second pipe 104 from the first gas supply sources 42, 44, 50, 60; and a breaking operation unit 23 that breaks the rupture disk 30 when the pressure of the fluid F1 exceeds a predetermined pressure.SELECTED DRAWING: Figure 1 【課題】弁駆動システムにおいて、弁を適切に駆動できるようにする。【解決手段】第１の配管１０６に所定圧力以上の気体Ｇ１が供給されると、流体Ｆ１の流通経路を形成する気体作動弁７１と、所定圧力以上の気体Ｇ１を発生させる第１の気体供給源４２，４４，５０，６０と、破断されると第１の気体供給源４２，４４，５０，６０から流入した気体Ｇ１を第２の配管１０４に供給する経路を形成するラプチャディスク３０と、第２の配管１０４に第１の気体供給源４２，４４，５０，６０から気体Ｇ１が供給されると、第１の配管１０６と第２の配管１０４とを導通させる切替弁２１と、流体Ｆ１の圧力が所定圧力を超えるとラプチャディスク３０を破断させる破断操作部２３と、を弁駆動システムＳ１に備えた。【選択図】図１
