China Bellow Seal Globe Valve Manufacturer, Factory and Supplier. Bellow Seal Globe Valve is a specially designed valve suitable for use in industries dealing with a hazardous medium where even minute leakages can be extremely critical. With the exponential growth of new industries such as the chemical and nuclear industry, there is a growing abundance of flammable, hazardous, extremely poisonous, and toxic media flowing through the pipelines. This creates a high risk of leakage, explosion, and health hazards. So, Bellow Seal Globe Valve is used in such pipes and systems have specific stringent leakage and sealing requirements.

The need for a completely different approach required for the desired sealing & redundancy has led to the development of Bellow seal globe Valve.

The unique design of Bellow Seal Globe Valve and its efficiency to provide leak-proof operations makes it the best-suited valve for a wide range of applications, especially hazardous materials & where system media is at high temperatures. Durability, maintenance-free operations and cost-effectiveness is an added benefit with bellows valves.

How does Bellow Seal Globe Valve work?
Bellow Seal Globe Valve is a compact structure that is a kind of control valve which uses bellows for sealing the valve stem components. The bellows valve has a bellow inside, and the lower end of the stainless-steel bellows is welded to the stem to prevent the system fluid from eroding the stem. The other end is positioned between the body of the valve and the cover of the valve to create a permanent seal. This double seal configuration eliminates leakage i.e., even if the bellows collapses, the stem packaging will prevent further leakage. The bellows are welded to the valve stem to ensure stable operating efficiency and prevent the vibration of the valve stem induced by the movement of the valve insert.

Bellow Seal Globe Valve advantage:
1. The most prominent advantage of any bellows valve is the Double seal design (bellows + packing). So, even if the bellows fails, the stem packing will prevent any kind of leakage to meet the international sealing standards.

2. It minimizes any loss of medium fluid and ensures the safety and environmental protection. This will ultimately improve the safety of the plant where is bellows valve has been installed.

3. Bellow Seal Globe Valve can act as an energy saver as it contributes to minimizing energy losses due to leakage.

4. Since the leakage is minimized, it prevents frequent maintenance of the valve. So, it leads to longer valve life.

5. Owing to longer service life, operating and maintenance cost is considerably reduced.

6. The rugged bellows seal design ensures zero leakage from the valve stem, thereby providing the maintenance-free conditions.

7. The safety of working personnel is improved with the installation of a bellows valve as emissions of inflammable, toxic, and hazardous chemicals can be minimized.

Bellow Seal Globe Valve application
1. Bellow Seal Globe Valve eliminates the risk of leakage of the process fluid and are therefore ideally suited for applications where leakage cannot be tolerated from the valves. So, places where highly hazardous materials such as hydrogen, ammonia, chlorine, and other similar poisonous or explosive material are handled, these valves are preferred.

2. It is suitable for use as a shut-off valve with heat-conducting oil, toxic, flammable, highly permeable, environmentally polluting, and radioactive fluid pipelines. It can be considered as a high-quality product for creating a leak-free factory.

 3.To name a few, bellows seal globe valve is highly used in petrochemical industries, electronics industry, various plants, vacuum industries, etc.
