This course
provides a total in-depth insight into the valve and actuator technology – not
only does the course analyse 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’.
- 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
