A bellow sealed globe valve is an essential component in many industries, such as chemical, oil and gas, and petrochemical industries. It is a type of industrial valve used to regulate and control the flow of fluids, gases, and other media through a pipeline or system. These bellows valves are widely used because of their unique design, which includes a bellows seal that protects the stem from corrosion and prevents fluid from eroding the stem. So it’s very common to see the condition for corrosive or toxic media. Bellows sealed globe valve with protected bellows in straight type, Y-type or corner type; with flanges or butt weld ends and safety gland packing. The bellows seal globe valve consists of body, disc, stem, bonnet, bellows seal, and packing. The valve body is the primary component that houses the valve disc, which controls the flow of media. The valve stem connects the valve disc to the actuator or handwheel, which opens or closes the valve. The bonnet covers the stem and packing and the bellows valve provides a seal to prevent leakage.
