Ball valve or wing valve is in the category of shut-off valves and will be damaged in the semi-open state. This valve is also used in the food, milk, dairy, acid and industrial industries of edible oils. The blocker of the flow channel, which will move 90 degrees through the valve stem, is responsible for opening and closing the valve. A hole has been installed in the cannon that will be placed in the open state along the flow channel. Stainless steel ball valves are used in industrial applications and in high pressure and temperature ranges. For corrosive permeable fluids or in the food industry, stainless steel ball valves have a special application. The disconnection of the flow in the manual type is done by a so-called gas handle.
