Abstract
A gate valve adapted for use in oil and gas operations, such as, for example, fracturing or gravel-packing operations. In an exemplary embodiment, the gate valve includes a valve body, which defines an internal region; a first fluid bore intersecting the internal region and defining a first interior surface in the valve body; and a first annular recess formed in the first interior surface and adjoining the internal region. A first seat element defines a second fluid bore and extends within the first annular recess. A first protective sleeve extends between respective portions of the first seat element and the valve body. The first and second fluid bores have first and second full-bore inside diameters, respectively. The first protective sleeve has a third full-bore inside diameter that is substantially equal to each of the first and second full-bore inside diameters.
