Understanding Bellow Seal Valves: Types, Applications, and Advantages
Bellow seal valves are of paramount importance across a wide spectrum of industrial applications. Their significance stems from their ability to provide absolute leak prevention, coupled with exceptional durability and a heightened level of safety. The unique design of these valves centers around a metallic bellow, which serves a critical function. This bellow effectively eliminates the need for traditional gland packing, a common source of leakage in conventional valve designs. By removing the gland packing, bellow seal valves guarantee zero fugitive emissions, preventing the escape of process fluids into the environment.
