Product Overview
The SMC XLF-50H0 is a high vacuum angle valve engineered by SMC Corporation, a global leader in pneumatic and vacuum control technology. This valve utilizes a bellows-sealed, pneumatically actuated angle body design to provide reliable isolation and conductance control in high vacuum process lines. Unlike standard hydraulic directional valves, the XLF series is purpose-built for vacuum service, where the angle configuration minimizes flow resistance and enables rapid evacuation and venting. The XLF-50H0 is a direct-acting, normally closed (N.C.) valve that opens via an external pilot air signal, making it ideal for integration into automated vacuum systems requiring precise, repeatable shut-off performance.
