    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
