A vertical shut-off valve is provided to get instant access of a fluid supply delivered from a pressurized inlet source to the outlet of the valve housing body. A movable stem assembly has of an upper member, a ring seal, and a base plate is engaged with a valve seat as the body of the stem assembly is being passed through the opening of the valve seat. The stem assembly urged in a closed position by the pressures from the compression spring and the inlet fluid, being moved away from the valve seat by the external pushing force on the pushbutton assembly, allows the flow passed through the valve seat between the body of the stem assembly and the inner recesses of the valve seat opening. The valve housing body containing the stem assembly is secured with a bottom cover with a ring seal and a top cover which is adjustably placed to lock the ring seal to achieve the sealing and the appropriate movement of the stem assembly.
