Operation: Handwheel

Pressure Seal Gate Valves are designed in accordance with API 600 and ASME B16.34 for high-temperature and high-pressure applications. These valves are widely used in fossil fuel power plants. Compared to bolted bonnet joint valves, pressure seal valves offer more reliable sealing of the bonnet joint, making them more compact, rigid, and cost-effective for maintenance in high-temperature and high-pressure services.

Product Features

Pressure Seal Gate Valves are designed with materials and features that ensure excellent performance in steam-generation stations, industrial chemical plants, and thermal power plants. They are available in both Cast Steel and Forged Steel body designs, providing flexibility for various application needs. These valves are known for their simple structure and reliable operation, with the ability to accommodate slight flexible deformation to compensate for deviations in the sealing face angle, enhancing performance. Additionally, the seat and gate disc seal surfaces are overlaid with iron-base alloys, cobalt-base alloys, or carbide alloys for extended durability.
