Learn what happens when a control valve fails in a process plant and how to protect your equipment. This video covers:

The main functions of control valves as final control elements
Consequences of control valve failure due to instrument air loss or mechanical issues
Selecting the proper failsafe action (open, close, last position)
Protecting pumps and process equipment with shutdown systems
Considering pressure relief valves (PSVs) for control valve failure scenarios
Understanding control valve failure is critical for process safety and smooth plant operations. We explain key considerations like failsafe positions, shutdown interlocks, and PSV sizing.

Whether you're a process engineer, chemical engineer, or work with control valves and instrumentation, this video provides valuable insights. Optimize your plant's safety and reliability by properly designing for control valve failures.
