A pressure let-down valve assembly for handling pressurized liquids which contain abrasive solids including a valve adapted for handling such liquids and a flow reversal means for changing the direction of the flowing liquid. The flow reversal means contains a chamber having an outlet located at a point which permits a sufficient amount of liquid to accumulate therein to absorb at least a portion of the energy of the flowing solids in the liquid.
