Course Outline
Topics:
Speed and Flow Rate Formula
Needle Valve
Differential Pressure
Pressure Compensated Valves
Meter-Out and Meter In
Objectives:
• Using a system schematic, explain the conditions that affect flow in a hydraulic system.
• Using a system schematic, explain how changing the flow rate in a hydraulic system affects the performance of the actuator.
• Identify the schematic symbols for flow control valves.
• Identify the functions of ports on a flow control valve.
• Describe the operation of a needle valve, and trace the path of the fluid through the valve.
• Describe the operation of a pressure-compensated flow control valve, and trace the path of the fluid through the valve.
• Describe the operation of a check valve.
• Using a system schematic, describe the operation of meter-in and meter-out circuits.
