    For air-operated control valves, electrical signals from the control system are converted to an air pressure for the valve actuator in a current/pneumatic I/P converter. Upon loss of pneumatic or hydraulic pressure valves may fail to an open (FO) or fail to a closed (FC) position. Some instrumentation is self actuating.

    In this method, the process gain (k p) is equal to the change in output divided by the change in input. The dead time θ is the amount of time between when the step change occurred and when the output first changed. The time constant (τ p) is the amount of time it takes for the output to reach 63.2% of the new steady-state value after the step ...
