Rising stem gate valve

Rising stem gate valves are a type of valve used in pipeline systems to control the flow of fluids. They are designed with a vertical stem that rises from the center of the valve body, allowing for easy operation and maintenance. The valve is opened by lifting the stem, which rotates a disc or plug to align with the valve seat and allow fluid to flow through. To close the valve, the stem is lowered, causing the disc or plug to seal against the valve seat and stop the flow of fluid. Rising stem gate valves are commonly used in industries such as oil and gas, chemical processing, and water treatment.
