Split gate valve
First Claim
1. A system, comprising:
- a valve assembly, comprising;
a valve body having a fluid passage that intersects with a valve cavity, wherein the valve cavity has four interior sides and four corner portions extending straight along an axis of the valve cavity directly from a first body side toward an opposite second body side of the valve body, and the valve body has four exterior sides extending straight along the axis directly from the first body side toward the opposite second body side of the valve body; and
a valve disposed in the valve cavity, wherein the valve is split into first and second valve sections that are biased apart from one another against opposite sides of the valve cavity, the valve comprises four sides having surfaces extending straight lengthwise along the axis and contacting the four interior sides of the valve cavity, the valve comprises four non-right-angled side portions extending straight lengthwise along the axis and facing the four corner portions of the valve cavity, and the valve comprises a valve bore extending through the first and second valve sections; and
a rolling actuator coupled to the valve, wherein the rolling actuator is configured to open or close the valve relative to the fluid passage by moving the valve along the axis and positioning the valve bore in or out of the fluid passage.

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.
