Abstract
An operating system for switching a coker switch valve to drum A, drum B, and bypass. The system has a shear pin linkage between the actuator and the valve stem and a position indicator independent of the actuator, to maintain functionality in the event of shear pin failure; and/or lockout functionality to prevent an inadvertent switch to bypass when switching between drum A and drum B and to lock down bypass mode to prevent an inadvertent switch from bypass to an open drum.
