Zusammenfassung:	The present invention relates to a fuel tank isolation valve. The fuel tank isolation valve of the present invention comprises: a first valve (31) in which a valve assembly (30) which opens and closes a flow path is operated by an electromagnetic force of a solenoid part; and a second valve (32) installed at the interior of the first valve (31) and operated by a differential pressure between a fuel tank pressure and a canister pressure. According to the present invention, An interior structure of a valve housing is simplified, a size is reduced, and assemblability is improved. 본 발명은 연료탱크 차단밸브에 관한 것으로, 유로를 개폐하는 밸브조립체(30)가 솔레노이드파트의 전자기력에 의해 작동되는 제1밸브(31)와, 제1밸브(31)의 내부에 설치되어 연료탱크 압력과 캐니스터 압력의 차압에 의해 작동되는 제2밸브(32)를 포함한다. 밸브하우징의 내부 구조가 단순해지고, 크기가 감소되며, 조립성이 향상되는 효과가 있다.
