PURPOSE: A valve equipped with a water leakage prevention member is provided to improve the air-tightness of a disk on the pressure of forward and reverse fluid actuating on the disc. CONSTITUTION: In a valve equipped with a water leakage prevention member, a disc(10) comprises a forward direction contact part(10-1) and a backward direction contact part(10-2). The forward direction contact part blocks the pressure of the fluid applied on the disc in a forward direction. The backward direction contact part blocks the pressure of the fluid applied on the disc in a backward direction. The disc is divided into the forward direction contact part and the backward direction contact part so that a fixing bolt is coupled with the bolt hole formed on the disk.
