BELLOW SEAL GATE VALVE MANUFACTURERS IN EUROPE

Valvesonly Europe is recognized Bellow Seal Gate Valve Manufacturers in Europe, producing leak-proof and maintenance-free valves for toxic, hazardous, and high-temperature media. Our valves ensure complete environmental protection and long-term reliability.

What is a Bellow Seal Gate Valve?

A Bellow Seal Gate Valve is a purpose-designed gate valve with the use of a metal bellows in place of traditional packing to seal the stem. This design prevents any leakage around the stem, providing a hermetic seal, particularly useful for important operations with dangerous or flammable media.

Why Required?

Bellow seal gate valves are necessary where leakage cannot be tolerated under any circumstances, like in nuclear, chemical, or steam applications. They improve safety, minimize emissions, and decrease maintenance costs, and thus are best suited for high-integrity systems.

Key Components of Bellow Seal Gate Valve

• Body and Bonnet (Carbon Steel, Stainless Steel)
• Flexible Metal Bellows
• Stem and Gate Disc
• Bonnet Gasket
• Backseat Arrangement
• Seat Rings (Hard-Faced or Soft-Seated)

Working Principle

The valve works by translating the gate through a rising or non-rising stem. External fluid leakage is avoided by a welded or mechanically supported bellows making a seal between the body and stem. The bellows gets compressed and expands with movement of the stem but remains in integrity.

Benefits of Bellow Seal Gate Valve

• Zero stem leakage – eco-friendly
• Suitable for high-temperature, high-pressure service
• Minimizes maintenance and downtime
• Improves plant safety
• Compliant with emission and environmental regulations

Functions of Bellow Seal Gate Valve

• Fluid isolation without external leakage
• Safe handling of hazardous, toxic, and radioactive media
• Minimum turbulence full bore flow control
• Both manual and automatic systems suitable for
