PURPOSE: A gate valve is provided to easily return a fluid path sealing member to a slide space of a first actuator when opening a fluid path closed with the fluid path sealing member. CONSTITUTION: A gate valve comprises a housing(130), a fluid path sealing member(140), a first actuator(150), an anti-corrosion sealing member(160), and a second actuator(170). The housing has a fluid path(110) connected to an inlet part(111) and an outlet part(112) and a slide space(120) bored in a direction perpendicular to the fluid path. The fluid path sealing member is inserted in the slide space in order to open and close the fluid path. The first actuator transfers the fluid path sealing member within the slide space. The anti-corrosion sealing member vertically moves in the fluid path when the fluid path sealing member closes the fluid path in order to raise the fluid path sealing member to the inlet part and open/close the slide space. The second actuator drives the anti-corrosion sealing member up and down. |
