A hydraulic valve regulates and controls the hydraulic system’s fluid. Valves are classified based on the power to be transmitted, their function, the control, and their design. In this chapter, you will learn about the different classifications of hydraulic valves.
Learning Objectives
  • Describe the purpose of a hydraulic valve
  • Understand how a hydraulic valve works
  • List the different classifications of hydraulic valves
  • Describe the different types of pressure valves
  • Understand the use of directional valves
  • Describe classifications of shut-off valves
  • Understand the different types of flow valves
  • Describe on/off valves
  • List the different types of proportional valves
  • Describe the features of proportional control valves
  • Describe the function of servo valves
  • List the advantages and applications of cartridge valves
  • Describe the main uses of logic valves

Piping and tubing transport hydraulic energy throughout the circuit of a hydraulic system. This piping may be flexible or rigid. When flexible or rigid piping are not the best solution, connection blocks may be used. In addition, several types of instruments measure pressure and flow in hydraulic circuits. 
Learning Objectives
  • Understand the use of piping and tubing
  • Describe the features of flexible and rigid piping
  • Recognize the difference between fittings and one-touch fittings
  • List the two connection types of rigid piping
  • Understand the use of connection blocks
  • List the types of pressure measuring instruments
  • Describe how a pressure gauge works
  • Understand the functions of a pressure switch and pressure transducer
  • List the types of flow measuring instruments
  • Identify what a multimeter can measure
