Pressure Seal Gate Valve is designed in accordance with API 600 for service of high temperature and high pressure and is widely used in nuclear plant and fossil fuel power plant. Compared with bolted bonnet joint valves, they provide absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.
