真空蝶阀主要用于接通或切断真空管路中的气流、适用介质为纯净空气或非腐蚀性气体。
Fit rough, bypass, and forelines thatrequire high conductance, low profile, rapid opening, and throttling action.
Features
Manually actuated (pneumatic and motorized available on request)
Remove easily from the line for servicing
High vacuum valves rotate open to give ahigh gas conductance path
Pass a leak test on a helium massspectrometer with a sensitivity of 2 x 10-10 std. cc/sec. before shipment
Recommended in operating conditionsinvolving frequent changing and cleaning; recommended for applications notrequiring line of sight or mechanical movement through the bore
