Product Features

The design and material selections ensure excellent service in steam generation stations, industrial chemical plants, and thermal power plants. KOSEN Pressure Seal Gate Valves are available in both Cast Steel and Forged Steel body designs, offering flexibility to meet various application requirements. These valves are known for their simple structure, reliable performance, and the ability to undergo slight flexible deformation to compensate for deviations in the sealing face angle during manufacturing, enhancing process efficiency. Additionally, the seat and gate disc sealing surfaces are overlaid with iron-base alloy, cobalt-base alloy, or carbide alloy for extended durability.
