The high vacuum large gate valve series is designed to provide reliable isolation for applications that require super large sizes (such as space simulation applications). The design specifications of this series can reach up to DN3000mm (118"), meeting high vacuum requirements of up to 1x10^-8. It can be customized in various ways, such as pneumatic drive, flange connections, rough pumping ports (bypass ports), exhaust or metering ports, thermal insulation devices, and more.
