Electric actuator for coke drum unheading valve

An electric actuator is provided for operating an unheading valve of a coke drum. The electric actuator includes a driving element comprising a planetary roller screw for actuating the unheading valve. By using a planetary roller screw, rather than hydraulics for the driving element, the electric ac...

Beschreibung
Zusammenfassung:	An electric actuator is provided for operating an unheading valve of a coke drum. The electric actuator includes a driving element comprising a planetary roller screw for actuating the unheading valve. By using a planetary roller screw, rather than hydraulics for the driving element, the electric actuator of the present invention can be used in place of hydraulic actuators while still providing sufficient power and reliability for use with an unheading valves of a coke drum.
