BELLOW SEAL GLOBE VALVE MANUFACTURERS IN INDIA
Speciality Valve is among the prominent Bellow seal globe valve manufacturers in India that offers dependable and leak-proof valve solutions for severe applications. Such valves are particularly designed to ensure no leakage, especially in risky or high-temperature environments where fugitive emissions need to be reduced.
Why Required?
Bellow seal globe valves play a critical role in the applications where leakage of dangerous, flammable, or precious fluids can cause safety issues, environmental issues, or economic loss. They provide an advanced sealing device, particularly appropriate for steam, gas, and chemically corrosive fluids.
Key Components of Bellow Seal Globe Valve:
1) Valve Body: Carbon steel, stainless steel, or alloy steel
2) Bellows: Multi-ply or single-ply metal bellows for extended life
3) Bonnet: Bolted or welded, ensuring greater safety
4) Disc & Seat: Throttling or shut-off design, hardened sealing surfaces
5) Stem & Gland: Attached to bellows to prevent packing leaks
Working of Bellow Seal Globe Valve:
It works by handwheel rotation moving the disc and stem to govern flow. The valve stem is welded to a metallic bellows between the valve bonnet, forming a hermetic seal with no leakage of process fluid into the atmosphere. This design features zero leakage throughout the stem.
Advantages of Bellow Seal Globe Valve:
1) Zero stem leakage by welded bellows
2) Long working life and minimal maintenance
3) Hazardous and high-temperature media safety
4) Avoids contamination of the atmosphere
5) Best for vacuum and pressure services
Functions of Bellow Seal Globe Valve:
1) Throttling and control of fluid flow
2) Isolation in thermal oil and steam systems
3) Avoidance of external leakage
4) Assuring safe handling of toxic or combustible fluids
Types of Bellow Seal Globe Valve:
1) Bolted bonnet bellow seal globe valve
2) Pressure seal bellow seal globe valve
3) Angle type bellow seal globe valve
4) Forged and cast bellow seal globe valve
