Pressure seal gate valves are designed in accordance with 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 valves, they offer superior sealing reliability at the bonnet joint, providing a more compact, rigid design. This results in reduced maintenance costs and enhanced performance in demanding high-temperature and high-pressure environments.
