Bellows Sealed Valve

The Bellows Sealed Valve delivers complete, zero leakage sealing to protect a facility, workers, and the surrounding environment. By replacing conventional packing with a highly engineered welded metal bellows that smoothly expands and contracts with a system, it actively prevents dangerous stem leaks into the atmosphere.

When traditional gland seals fail under the intense demands of synthetic fibre production or high temperature heat transfer systems, this valve provides reliable, enduring performance. For sensitive applications in the food, beverage, and pharmaceutical industries, maintaining a pristine environment is essential. The specialised design supports strict vacuum and ultra high vacuum conditions by blocking external air from infiltrating the stuffing box. This ensures expensive and high purity fluids remain completely uncontaminated, giving total confidence in the daily operations and regulatory compliance.

Summary: 
Used to provide absolute, zero leakage sealing in industrial systems handling hazardous, toxic, expensive or high purity fluids
Welded metal bellows that expands and contracts, preventing stem leaks into the atmosphere

The vacuum and ultra high vacuum prevents external air from entering the system through the valve stuffing box
Ideal for synthetic fibre or heat transfer systems where conventional gland seals would fail

Applications: 
Commonly used in food, beverage and pharmaceutical industries
