Cast Steel High Pressure Gate Valve is a gate valve product specifically designed for high-pressure operating conditions. The valve body is manufactured from high-quality cast steel material, providing high strength and good pressure resistance. The closing element of the valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The valve can only be fully opened or fully closed, and cannot be used for regulation and throttling. Cast Steel High Pressure Gate Valves feature compact structure, good sealing performance, and high pressure resistance. They are suitable for high-pressure and high-temperature operating environments and are widely used in high-pressure pipeline systems in industries such as petroleum, chemical, power, and metallurgy.
