Our pressure seal gate valves are designed in accordance with API 600 and ASME B16.34 standards for high-temperature and high-pressure applications and are widely used in fossil fuel power plants. Compared to bolted bonnet joint valves, these valves provide absolutely reliable sealing of the bonnet joint, making the pressure seal valves more compact, rigid, and cost-effective in terms of maintenance for high-temperature and high-pressure service.
