Product Overview
The VAT 28332-GE71-0003/0068 is a high-precision vacuum isolation valve engineered by VAT Group, a global leader in vacuum valve technology. This component operates as a pneumatically actuated process valve designed for reliable shut-off and isolation of vacuum lines in demanding industrial and semiconductor process environments. Unlike hydraulic directional or pressure control valves, this unit is specifically configured for vacuum service, utilizing a pneumatically driven actuator to achieve positive sealing against atmospheric pressure differentials. Its robust construction ensures leak-tight performance, making it an essential component for maintaining process integrity in high-purity and high-vacuum systems.
