Unox Metal Bellows Globe Valve
The Unox metal bellows globe valve provides leak-tight and safe flow control in steam and industrial pipelines. Thanks to its durable metal bellows structure, it ensures long service life and reliable operation under demanding conditions.
What Is a Metal Bellows Globe Valve?
A metal bellows globe valve is a type of control valve integrated into piping systems to ensure high sealing performance. In this design, sealing is achieved through a metal bellows structure, which completely isolates the internal process fluid from the external environment. This makes it especially suitable for systems handling hazardous gases or chemicals.
The multi-layer metal bellows is integrated into the valve body and allows movement of internal components without leakage. It offers high resistance to temperature, chemicals, and wear, extending valve lifespan and minimizing maintenance needs.
Where Is It Used?
Metal bellows globe valves are widely used in applications where sealing safety is critical. Common usage areas include:
- Refineries
- Petrochemical plants
- Chemical process systems
- Steam and thermal oil lines
- Power plants
- Inert gas distribution systems
They are essential in environments where toxic or hazardous fluids must be safely contained.
