A bellow sealed valve is a specialized valve designed for managing fluid flow under challenging conditions, including high-pressure or vacuum environments.
This valve stands out for its robust resistance to the dynamic conditions of pressure and temperature fluctuations. It incorporates a flexible bellow within the valve body, made from durable materials like metal or alloys, featuring corrugated tubes that adeptly adapt to changes in pressure. This design ensures an effective seal against fluid leakage when the valve is closed, thanks to the bellows' ability to expand and contract.
Commonly utilized in the regulation of liquid or gas flow, bellow sealed valves play a crucial role in maintaining pressure balance and ensuring leak-proof operation within various systems.
