A Tank Bottom Valve, also known as a Bottom Outlet Valve or Bottom Drain Valve, is a type of industrial valve specifically designed for installation at the bottom of tanks, vessels, or reactors. These valves are used to drain, empty, or discharge liquids, slurries, or other fluids from the bottom of storage tanks or process vessels.

Tank Bottom Valves are essential components in industries such as chemical processing, pharmaceuticals, food and beverage, and wastewater treatment, where controlled and efficient drainage of liquids is crucial for operational safety and process efficiency.
