Summary -
This unit is designed to familiarize trainees with the basic design and
operation of various types of valves used in hydraulic systems. After completing
this unit, trainees will be able to describe the functions of flow and
pressure in a hydraulic system, and identify and describe various types of
manually adjusted valves, sliding spool valves, and spring-biased valves.
They should also be able to describe various ways in which valves can be
actuated. Subject(s) -
