Abstract:
A wedge guide has two wedge surfaces. The first angled surface engages a first seat retainer positioned on one side of a gate to lock the first seat retainer in a first pocket. The wedge guide has a second angled surface that engages a second seat retainer on the other side of the gate that locks the second seat retainer in a second pocket. The wedge guide does not affect the movement of the seats that move axially between the gate and the respective seat retainers. Two wedge guides are preferably utilized on opposite non-sealing sides of the gate so that the gate slides between them.

Claim (Index 1):
A wedge guide for a gate valve, comprising:\n said gate valve comprises a valve body that defines therein a flow bore through said valve body and a gate cavity that intersects said flow bore, a gate is disposed in said gate cavity across said flow bore, said gate being moveable to open and close said flow bore, said valve body defining a first pocket in said valve body on one side of said gate and a second pocket in said valve body on an opposite side of said gate, a first seat assembly surrounding said flow bore, said first seat assembly being positioned between said first pocket and said gate, said first seat assembly comprising a first seat and a first seat retainer, said first seat being adjacent to said gate, said first seat being slidable with respect to said first seat retainer, said first seat being axially movable between said gate and said first seat retainer along an axis through said flow bore, a second seat assembly surrounding said flow bore, said second seat assembly being positioned between said second pocket and said gate, said second seat assembly comprising a second seat and a second seat retainer, said second seat being adjacent to said gate, said second seat being slidable with respect to said second seat retainer, said second seat being axially movable between said gate and said second seat retainer along an axis through said flow bore; and a wedge guide, said wedge guide comprising a first wedge surface that engages said first seat retainer to urge said first seat retainer into said first pocket to prevent movement of said first seat retainer with respect to said first pocket, said wedge guide comprising a second wedge surface that engages said second seat retainer to urge said second seat retainer into said second pocket to prevent movement of said second seat retainer with respect to said second pocket.
