What you’ll be able to do

  • Recognise every common valve and actuator symbol, and what “fail closed” or “fail open” means
  • Read instrument tags like LIC-101 or PSHH-107 using ISA 5.1 letters
  • Follow a control loop: transmitter → controller → control valve
  • Spot the safety systems: SDV, BDV, PSV and interlocks
  • Decode a line number such as 6″-P-1102-A1A, reducers and spec breaks
  • Follow the flow across sheets with off-page connectors

One running example: every lesson uses the same three-phase separator, V-100, so the whole drawing makes sense by the end.
