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

Product Features

» The design and material selection of Pressure Seal Gate Valves ensure excellent service in steam generation stations, industrial chemical plants, and thermal power plants. Available in both Cast Steel and Forged Steel body designs, these options make the Pressure Seal product line ideal for a wide range of applications.
» These valves are known for their simple structure, reliable performance, and the ability to accommodate slight flexible deformation to compensate for sealing face angle deviations during manufacturing, thereby improving process performance. Additionally, the seat and gate disc seal surfaces are overlaid with iron-base alloy, Co-base alloy, or carbide alloy for extended service life.
