Course Description

This course provides a total in-depth insight into the valve and actuator technology – not only does the course analyze control valves but also focuses on whole host of other types including: check valves, shut-off valves, solenoid valves and pressure relief valves. A methodology is presented to ensure the optimum selection of size, choice of body and trim materials, components and ancillaries. Whilst studying the correct procedures for sizing, delegates will also learn the correct procedures for calculating the spring ‘wind-up’ or ‘bench set’.

Course Objectives

  • Appreciating the basic theory of flow through a control valve
  • Understanding the major technologies used in the final control element
  • Performing flow and system pressure head loss calculations
  • Appreciating the principles of cavitation control and noise reduction
  • Selecting optimum materials of construction to avoid corrosion and erosion
  • Understanding the correct requirements for trim selection
  • Understanding control valve characterisation and characteristic profiling
  • Using the control valve seat leakage classifications
  • Picking the optimum valve-actuator combination
  • Understanding the principles of preventive maintenance through the application of signature analysis
  • Gaining an insight into the application and limitations of safety relief valves
