Our pressure seal gate valves are designed in compliance with API 600 and ASME B16.34 standards, making them ideal for high-temperature and high-pressure service. These valves are widely used in fossil fuel power plants. Unlike bolted bonnet valves, pressure seal gate valves offer a highly reliable bonnet joint seal, ensuring greater compactness, rigidity, and improved performance. Their design makes them more cost-effective in terms of maintenance, particularly in high-temperature and high-pressure applications.
