Abstract
A first cutter is provided on an edge region of a first surface of a gate valve member to be moveable across the flow path with the gate valve member along a first cutting plane. A first seal pocket is defined by a depression in the first surface of the gate valve, wherein a second peripheral seal surface is provided within the first seal pocket. The first valve seat and the gate valve member are axially moveable relative to each other to permit a portion of the first valve seat to become received into the first seal pocket of the gate valve member when said gate valve member is located within its second position to provide sealing engagement between the first and second peripheral seal surfaces.
