Bellow Seal Valve
At WOGS, we supply reliable bellow seal valves engineered to provide zero stem leakage in critical flow systems. Designed with a flexible metal bellows that completely seals the valve stem, these valves prevent fluid or gas from escaping into the atmosphere, making them ideal for hazardous, toxic, or high-purity applications.
Bellow seal valves are commonly used in chemical processing, petrochemical, pharmaceutical, oil and gas, and nuclear power industries where environmental safety, product purity, and operator protection are vital.
What Is a Bellow Seal Valve?
A bellow seal valve features a metal bellows welded to the valve stem and bonnet, forming a hermetic seal that eliminates fugitive emissions around the stem packing area. This robust design ensures reliable shutoff and extends valve life by preventing leakage that can occur with standard gland packings.
