Basic introduction of Bellows Seal Globe Valve

Bellows Seal Globe Valve is the introduction of foreign advanced technology, the use of foreign metal bellows sealing technology manufacturing, high-performance elastic metal bellows, expansion, and fatigue life is particularly long. The bellows seal design completely eliminates the shortcomings of the common valve stem packing seal that is prone to leakage due to rapid aging. It not only improves energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment.

Structural Design

Bellows Seal Globe Valve has a double seal design (bellows + packing). If the bellows fail, the stem packing will also be avoided. The Bellows Seal Globe Valve has no fluid loss, reduces energy loss, and improves plant equipment safety. Seal surface overlay welding Co-based carbide, wear resistance, corrosion resistance, good anti-friction performance, long service life, reduces the number of maintenance, reduces operating costs. The rugged bellows seal design ensures zero stem leakage and provides maintenance-free conditions. Bellows Seal Globe Valve stem is tempered and surface nitride treated for good corrosion and friction resistance. Stem lift position indication is more intuitive.

Applications

Bellows Seal Globe Valve is a valve with bellows as the stem sealing element, Bellows Seal Globe Valve is commonly used in applications that require strict stem sealing, such as in high vacuum applications and in the nuclear industry. By using bellows instead of a stuffing box or with a stuffing box on common valves, the stem part can be leak-free to prevent leakage of radioactive substances or valuable materials or to maintain a high vacuum. The bellows expand and retract with the lifting and lowering of the valve stem, and the highest working pressure depends on the pressure resistance and fatigue strength of the bellows.

Advantages

What are the advantages of using Bellows Seal Globe Valve? With the rapid development of modern industries such as chemical and nuclear industries, the number of pipelines with flammable, explosive, highly toxic, and radioactive media is increasing, and the valves used on these pipelines and devices have special and strict requirements for their external leakage. The use of general packing sealing devices can no longer meet the requirements, therefore, the need to use the bellows stem sealing structure. So what are the advantages of using Bellows Seal Globe Valve? If the bellows fail, the stem packing will also avoid External leakage and meets international sealing standards. Reducing fluid loss and improving the safety of industrial production are also the advantages of bellows seal globe valve. Long service life reduces the maintenance and operating costs. The robust bellows seal design ensures zero stem leakage and provides maintenance-free conditions.
