Product Overview
The VAT 10844-PE24-0005/0035 (OEM Reference: A-768815) is a high-precision vacuum isolation valve engineered by VAT Vakuumventile AG, the global benchmark for ultra-clean and high-vacuum flow control. Operating on a pneumatically actuated, normally-closed (NC) gate mechanism, this valve provides reliable on/off isolation of process gas and vacuum lines in demanding semiconductor, coating, and analytical environments. Its compact aluminum body and elastomer-sealed gate deliver fast actuation, low particle generation, and leak-tight sealing performance, making it a critical component for chamber isolation, load-lock sequencing, and pump protection in high-vacuum process tools.
