Product Features

» Excellence in Diverse Applications: The design and material selections make these valves highly suitable for steam-generation stations, industrial chemical plants, and thermal power plants.
» Versatile Body Designs: Most Pressure Sealed Gate Valves are available in both Cast Steel and Forged Steel body designs, catering to a wide range of application requirements.
» Superior Process Performance: The simple structure and reliable usage of these gate valves are further enhanced by their ability to create slight flexible deformation. This compensates for deviations in the sealing face angle that may occur during processing, thereby improving overall process performance.
» Enhanced Durability: The seat and gate disc seal surfaces are overlaid with iron-based alloy, cobalt-based alloy, or carbide alloy, ensuring long-lasting performance and durability.
