A valve is provided which is adapted for removable insertion in a valve body used for the control of the flow of fluid in a plumbing fixture. The valve includes a pair of discs in intimate movable contact with one another along a common interface. The first disc has at least one inlet aperture therethrough adapted to be positioned at one end in fluid communication with the inlet valve of the valve body and at the other end with the adjacent face of the second disc. The second disc has at least one passage aperture therethrough positioned so that relative movement between the discs will direct the apertures therein between the blocked shutoff position with the apertures of the discs out of alignment and the partially and completely overlapped position where fluid can flow through the discs. The discs are mounted in a sleeve and the discs and sleeve are connected to one end of a spindle. The interconnected discs, sleeve and spindle are removably mountable in a valve body. At least one outlet aperture in the sleeve is adapted to be positioned in fluid communication with an outlet on a valve body when mounted therein. At least one flow stabilizing insert is arranged at a predetermined point in the flow passageway between the at least one inlet aperture in the first disc and the at least one outlet aperture in the sleeve. The at least one insert is arranged in the at least one passage aperture in the second disc and extends with one end near the interface between the discs.
