Valve Manifold Boxes (VMBS)
Ultra-High Purity Gas Mixing Systems
Designed to precisely control the distribution of process gases to semiconductor tools, Carten VMBS lower the gas pressures to provide split gas lines and precise pressure measurement while providing a safe, single point for safety shutdown functionality.
Key Features
Safe, vented enclosures made to specification
FAT/ Validation to ensure plug & play supply
Components manufactured and integration (welding, cleanroom assembly etc) completed on site
Complete ownership of component and assembly for servicing / information requests
Typical Applications
Pressure stage-down from semiconductor gas cabinets and gas panels at semiconductor FABS, controlling the distribution of process gases to multiple semiconductor tools, lowering of gas pressures, controlled split gas lines to separate semiconductor equipment tools, single point for safety shutdown, application containment functionality.
