Bellow Sealed Valves are a new breed of Industrial process valves,designed to eliminate Valve leakage and are also known as 'Zero Leak Valves or' Emission FreeValves. ' In these Valves,conventional gland packing is appended/supplemented by a metallic Bellow Cartridge joined to the valve bonnet at one end,and the stem at the other end. A bellow is a long accordion-like tube. As the valve stem strokes,the bellow expands or compresses with the stroke movement. There are no sliding or rotating seals through which process fluid can pass.
