Pressure Seal Gate Valves are designed according to API 600 and ASME B16.34 standards for high-temperature and high-pressure service, making them ideal for use in fossil fuel power plants. Compared to bolted bonnet joint valves, pressure seal valves offer superior sealing reliability at the bonnet joint. This design makes the valves more compact, rigid, and cost-effective in terms of maintenance, particularly in demanding high-temperature and high-pressure environments.
