A bellow sealed valve, also known as a bellows seal valve, is a type of industrial valve designed with a flexible bellows to provide a hermetic seal between the valve body and the stem. The bellows, typically made of metal or other flexible materials, surround the stem and create a protective barrier that prevents the process fluid from leaking to the atmosphere.
The key components of a bellow sealed valve include:
Bellows: The flexible, accordion-like structure made of metal or flexible materials, such as stainless steel, designed to accommodate movement and maintain a leak-tight seal.
Stem: The stem is connected to the valve actuator and passes through the bellows. The stem movement is transferred to the valve disc or plug, allowing for control of flow through the valve.
Valve Body: The main structure of the valve that houses the valve components and provides the pathway for the fluid to flow through.

The bellows serve several important functions in a bellow sealed valve:
Leak Prevention: The bellows act as a barrier, preventing the process fluid from leaking into the environment and ensuring a leak-tight seal, even in high-pressure or high-temperature applications.
Environmental Protection: By creating a sealed environment around the stem, the bellows protect it from exposure to corrosive or harmful substances in the fluid, thus extending the valve's lifespan.
Bellow sealed valves are commonly used in applications where preventing leaks is crucial, such as in industries like pharmaceuticals, petrochemicals, chemicals, oil and gas, and other industrial sectors. These valves are preferred for their ability to provide a reliable and tight seal, ensuring safety, efficiency, and environmental compliance.
