Product Overview
The VAT 26434-KE21-CHR1/0049 is a high-precision vacuum isolation valve engineered by VAT, the global leader in vacuum valve technology. Operating on a pneumatically actuated gate valve principle, this component is designed to provide reliable, leak-tight isolation 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 or elastomer-sealed gate mechanism to achieve high conductance and minimal particle generation. It serves as a critical isolation point in load-lock chambers, transfer modules, and high-vacuum process lines, ensuring process integrity and protecting sensitive vacuum pumps from atmospheric exposure.
