A multiport valve having an inlet port and a plurality of outlet ports. The inlet port communicates with a main pressure chamber, and that chamber is separated from the outlet ports by a valving arrangement which includes a selector plate having an aperture therein for providing selective communication between the main pressure chamber and one of the outlet ports. A handle is provided to move the selector plate, and a detent, responsive to fluid pressure in the pressure chamber, is provided to lock the handle and the selector plate against movement when the chamber is pressurized. Thus, it is necessary to shut off a fluid supply pump prior to movement of the selector plate, and this feature minimizes the adverse effects of high velocity fluid across port gaskets as the selector plate is moved.
