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:

Valve Body: Carbon steel, stainless steel, or alloy steel

Bellows: Multi-ply or single-ply metal bellows for extended life

Bonnet: Bolted or welded, ensuring greater safety

Disc & Seat: Throttling or shut-off design, hardened sealing surfaces

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:

Zero stem leakage by welded bellows

Long working life and minimal maintenance

Hazardous and high-temperature media safety
