With the diagram listed in the url above if steam in this system needs to be Fail-safe in case there is a problem?
Should the steam valve Fail-open or Fail-close? Should the PIC be direct-acting or reverse acting? Should the TIC be direct or reverse acting? Is the control loop considered a Feedforward or Cascade control loop?
