    • The present invention features a coke drum de-heading system (10) without having to physically remove the head units. This is accomplished using a specially designed dual seated, linear motion goggle blind gate valve, or de-header valve (12), that is removably coupled to and seals against the flanged (42) portion of a coke drum (18) much the same way a conventional head unit would be attached. The de-header valve (12) is equipped with, among other things, a sliding blind (122) that is contained and capable of moving within an upper (34) and a lower (38) seat, wherein one of such seats is a floating dynamic, live loaded seat that is capable of automatic adjustment through one or more loading zones so as to seal the blind (122) between the upper (34) and lower (38) seats. The movement of the sliding blind (122) serves to open and close the de-header valve (12), wherein in a closed position, the de-header valve (12) is prepared to receive the resid byproduct feed from the refinery process used to manufacture coke (4). Once the drum (18) is full, the de-header valve (12) may be actuated (opened), wherein the coke (4) that has accumulated on the blind (106) is sheared by the upper (34) and lower (38) seats, thus de-heading the coke drum (18) and facilitating the removal of coke (4) using methods commonly known in the art.
