Main Features: The pressure seal valves are designed for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more...

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.
