The present invention relates generally to a non-clogging slurry nozzle apparatus and method for avoiding blockages in slurry nozzles associated with the jetting of mixtures of soluble and/or insoluble abrasives and high pressure fluids. The apparatus involves the use of a pressure actuator which opens and closes gates of a valve, permitting a compressed gas to enter the nozzle and remove all abrasive material from a nozzle when jetting is interrupted, thus preventing the abrasive material to remain in the nozzle where it may adhere with residual moisture and form blockages. The present invention lessens the opportunity for abrasive material blockages in slurry nozzles and improves the efficiency of cleaning operations by reducing the need to interrupt blasting operations to remove abrasive blockages from the slurry nozzle.
