Controller Action For Fail Safe Position
Controller action for fail safe position for Centrifugal Compressor

Esteemed members

Does Final Control element's fail safe position (Fail open /Close) dictate Controller's action (Direct or Reverse) ?

An antisurge Valve for Centrifugal Compressor is a fail open valve, what would be the Controller action for the associated PIC?
