API Ball Valve with Bellows

The API Ball Valve with Bellows is a high-performance industrial valve designed according to the American Petroleum Institute (API) standards. This valve is widely used in fluid handling systems, pipelines, and other industrial processes due to its superior leak protection and low maintenance requirements. The key feature of this valve is the bellows seal, which provides excellent sealing and minimizes fugitive emissions.

Description

Brief of API Ball Valve with Bellows

THINKTANK’s API ball valve with bellows features a three-stage sealing system. The primary seal is located at the lower end of the valve stem, utilizing a tapered seal that offers a metal-to-metal hard seal. The effectiveness of this seal increases with higher pressure. The second stage of sealing is provided by the bellows seal. As fluid enters the bellows through the first capillary-type seal, the pressure is significantly reduced, creating a stable and constant fluid environment. Consequently, the bellows experience a steady, unvarying force rather than alternating stress, which greatly enhances the working conditions and longevity of the bellows. The third stage of sealing is achieved through the use of conventional packing seals typically found in valves.
