Stainless Steel High Pressure Gate Valve is a gate valve product specifically designed for high-pressure corrosive medium operating conditions. Main components such as the valve body, valve cover, and gate are all manufactured from high-quality stainless steel material, providing excellent corrosion resistance and high strength. 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. Stainless Steel High Pressure Gate Valves not only have high pressure resistance but also excellent corrosion resistance, making them suitable for high-pressure and corrosive medium operating environments. They are widely used in high-pressure corrosive medium pipeline systems in industries such as chemical, petroleum, pharmaceutical, food, and power.
