In a process for checking and/or adjustment and/or assembly of valves, in particular electronically controlled injection valves for internal combustion engines, in which the valves are conveyed along a test line having successive test stands, a test line that is fully automatic and thus free from disturbing effects of manual or semi-manual operation, with optimized flow of material and objective measurement or test results, can be obtained by coordinating computer-controlled transport systems with one another and with computer-controlled test stands by use of a higher-level control.
