Product Overview
The VAT 26432-KA11-BSP1/0346 is a high-precision vacuum isolation valve engineered by VAT Group, a global leader in vacuum valve technology. Operating on a pneumatically actuated bellows-sealed mechanism, this valve is designed to provide reliable isolation and control of vacuum lines in demanding process environments. Unlike hydraulic directional or pressure control valves, this unit is specifically configured for vacuum service, utilizing a bellows-sealed stem to prevent atmospheric leakage and particulate contamination into the vacuum chamber. Its robust construction ensures leak-tight performance, making it an essential component for semiconductor manufacturing, thin-film deposition, and industrial vacuum coating systems.
