Pressure Seal Gate Valve
Main Features:
The pressure seal valves are designed for high temperature and high pressure service, commonly used in fossil fuel power plants. Compared with bolted bonnet joint valves, they offer a more reliable sealing solution, making them compact, rigid, and cost-effective in maintenance at extreme conditions.
These gate valves are known for their simple structure, reliable performance, and ability to allow slight deformation to compensate for angle deviations during manufacturing, enhancing process performance. The seat and gate disc sealing surfaces are often overlaid with iron-based, cobalt-based, or carbide alloys for long-lasting use.
