It is ultimately important to thrust the parts before assembling them together when repairing the common rail injectors. The control valve is one of those items that are almost impossible to tell whether it is acceptable or will fail during the Flow Test on the test bench by just looking at the surface condition using magnifiers or more developed cameras.

KO1815 Control Valve Testing Unit saves time and effort to start repair all over again just because of a misjudgment made at a visual check. It performs a SAFE and reliable test at 8 bar air pressure to make sure that the control valve is completely acceptable before assembling into an injector.
