The closing element of the Stainless Steel Threaded Gate Valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. It is installed via internal threaded connection. The gate valve can only be fully opened or fully closed, and cannot be used for regulation and throttling. The main components of this product, including the valve body, valve cover, and gate, are all manufactured from high-quality stainless steel materials, providing excellent corrosion resistance suitable for corrosive medium applications. The internal threaded connection makes the valve structure more compact and easier to install, suitable for pipeline systems with space constraints. Stainless Steel Threaded Gate Valves are widely used in pipeline systems in industries such as chemical, petroleum, pharmaceutical, food, and power.
