Abstract
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.

A system, comprising:
- a split gate valve, comprising:
- 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;
- and
- a rolling actuator configured 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.
A system, comprising:
- a split gate valve, comprising:
- a body comprising an opening into a cavity, wherein the opening is configured to reduce deflection of the body during operation of the split gate valve;
- and
- first and second gate sections coupled together to form a gate assembly configured to move along the opening into the cavity between an open position and a closed position.
A method, comprising:
- converting a rotational input into a linear motion to actuate a split gate valve via a rolling actuator;
- and seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.
