Directional control valves. (07-Flo)


Description
Directional control valves control the movement of actuators. In this unit we describe the construction and operation of directional control valves and discuss their schematic symbols. We also discuss both how pilot operation and proportional outputs work.

Total presentation time is 1 3/4 hours.

NOTE: Purchasing this course will enable your access for seven days only.
