The mechanical blockage of a directional control valve (DCV) spool can result in: D) cavitation.
DCV is an acronym for directional control valve and it can be defined as a fundamental component that is used to determine the path of fluid flow from one or more sources through an electric circuit in a pneumatic (hydraulic) system.
A spool comprises lands and undercuts and it is used for controlling fluid flow and connecting internal passages and port in a pneumatic (hydraulic) system.
In conclusion, cavitation is caused as a result of the mechanical blockage of a directional control valve (DCV) spool.
