Hydraulic Control Valves 341

Hydraulic Control Valves describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it moves through a hydraulic system. The proper placement of control valves contributes to the overall effectiveness of a hydraulic circuit. Hydraulic system operators use schematic diagrams when studying hydraulic circuits and control valves. Schematic diagrams include symbols for control valves and other system components. Understanding the functions of each type of hydraulic control valve and their proper placement within a hydraulic circuit helps ensure that a hydraulic system produces usable power. After taking this class, users will understand the main types of hydraulic control valves and their various functions. Users will also be able to identify schematic symbols for common control valves.
