Stainless Steel Gate Valve
A gate valve structure having a slab gate and a pair of opposed seat assemblies on opposite faces of the slab gate. A generally U-shaped spacer member of substantially the same thickness as the slab gate is loosely positioned between the opposed seat assemblies outwardly of the slab gate to maintain a predetermined minimum spacing between the seat assemblies. The U-shaped spacer member has a smaller thickness portion thereof in its center section to provide flexibility for permitting alignment of the spacer member upon canting or cocking of the seat assemblies.
