Product Overview
The VAT 351976/1868/9 is a high-precision vacuum isolation valve engineered by VAT Group, a global leader in vacuum valve technology. This component is designed for reliable sealing and flow control in vacuum and pneumatic process systems, operating on a mechanically or pneumatically actuated sealing mechanism rather than a hydraulic pumping principle. It serves as a critical isolation or roughing valve in industrial vacuum networks, ensuring leak-tight shutoff, minimal particle generation, and stable conductance characteristics. The valve is constructed for integration into demanding process environments where contamination control and repeatable cycling are essential.
