Product Overview
The Bellows Sealed Globe Valve is designed for applications requiring absolute zero stem leakage, especially in systems handling toxic, flammable, corrosive, or high-purity media.
A multi-layer stainless-steel bellows is welded to both the stem and bonnet, providing a hermetically sealed structure that eliminates external leakage throughout the valve’s operating life.
This valve is widely used in chemical processing, petrochemical plants, steam and thermal oil systems, and high-purity gas pipelines.
