ABSTRACT:
An alignment device for maintaining the relative alignment between a gate valve assembly and a valve bonnet positioned over the gate valve assembly wherein the valve bonnet has an interior surface. The alignment device includes a pair of substantially identical components wherein the components are securely connectable to each other when the alignment device is attached to the gate valve assembly. Each one of the components includes a body that has a peripheral portion. The peripheral portion is adjacent to the interior surface of the valve bonnet when the valve bonnet is positioned over the gate valve assembly. The body also has a transverse edge wherein the transverse edge contains an opening that receives a part of the gate valve assembly when the components are connected together.
