A fuel cut-off valve installed in a valve body including a supply path, a discharge path, and a valve seat formed between the supply path and the discharge path, and configured to regulate a flow of fuel by opening and closing the valve seat, comprising:

• a housing with which a connector for electric power and signal transmission is integrally formed;
• a coil assembly provided inside the housing and electrically connected to the connector;
• a core coupled to pass through the coil assembly and having a first operation groove formed therein;
• a plunger installed movably in the first operation groove and having a second operation groove, which is connected to the supply path, formed therein;
• a friction member interposed between the core and the plunger and configured to reduce friction;
• a pilot installed movably in the second operation groove and having a pilot orifice, which connects the second operation groove and the discharge path, formed therein;
• and
• a spring interposed between the core and the plunger and configured to elastically support the plunger so that the pilot comes in close contact with the valve seat.
