ABSTRACT A high pressure abrasive jet is created by feeding a mixture of carrier liquid abrasive material at high pressure through a conduit to a nozzle. The mixture may be formed at said high pressure. Valves which carry the high pressure mixture are provided with a trap above and a settlement volume below so that when flow stops, the abrasive material can settle from under the trap entirely into the settlement volume, thus leaving the valve to operate in clear carrier liquid. A high pressure abrasive jet can be formed by feeding carrier liquid and abrasive material into a vertically extending conduit leading to a nozzle at its lower end, the high pressure being generated by the head of the conduit's contents.
