A floatless outlet valve comprises a valve body having a vertically disposed overflow tube and a valve seat formed integrally at the lower end of the tube. A valve assembly is pivotably connected to the terminal end of the overflow tube by the rear end portion of arm extensions thereby allowing valve of the disc to be closable and operable with respect to the valve port. A cup-like control member with a valve rod is capable of discharging water in the tank completely or partially in accordance with the user's need.
