Patent number: 10443740Abstract: Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.Type: GrantFiled: November 28, 2015Date of Patent: October 15, 2019Assignee: Cameron International CorporationInventors: Loc Gia Hoang, Christopher Jude Gerace
