Description
Metal bellows globe valve is a type of valve with high sealing security that is integrated into pipelines to provide fluid control. In this type of valves, sealing is ensured by the bellows structure and contact with the external environment is completely cut off. Thus, safe working conditions are created, especially in systems where dangerous gases or chemicals are transported.
The bellows is integrated into the valve body with its multi-layered structure made of metal and allows the moving parts to operate in a leak-free manner. During operation, the areas in contact with the fluid are resistant to high temperature, chemicals and abrasion. Therefore, the life of the valve is extended and the need for maintenance is minimized.
Where is Metal Bellows Globe Valve Used?
This valve type is used extensively in industrial applications where sealing requirements are critical. It is especially preferred in refineries, petrochemical plants and chemical process lines. It can be safely applied in systems operating with steam, heat transfer oils and harmful gases.
It is also widely used in power plants, heating lines and inert gas distribution systems. In places where hazardous environments are present, this valve type plays a critical role in ensuring environmental and personnel safety.
What are the Technical Specifications?
Metal bellows globe valves contribute to system performance thanks to their technical qualities. They are generally produced with the following features:
-
Body Material: Stainless steel, cast steel or carbon steel
-
Bellows Material: 316L stainless steel
-
Gasket PTFE, graphite or metallic sealing
-
Connection Type: Flanged (according to DIN, ANSI standards)
-
Pressure Resistance: PN16, PN25, PN40
-
Temperature Range: -20°C to +450°C
-
Working Principle: Can be controlled by hand-operated, pneumatic or electric actuator
Each valve is put into use after leak tightness testing and performance checks.
Why Metal Bellows Globe Valve is Preferred?
Metal bellows globe valves maximize system safety thanks to their double sealing structure. Thanks to the complete sealing provided by the bellows structure, harmful gases are prevented from spreading into the environment. This reduces the environmental impact and offers a great advantage in terms of employee health.
In addition, thanks to the bellows technology, the maintenance period of the valve is extended and maintenance frequency is reduced. System downtime is minimized and production continuity is ensured. Since it is produced with materials with high chemical resistance, it can be used without any problems even in harsh environments.
Thanks to its ease of installation and compliance with standards, it can be quickly integrated into many different lines.
