Fine control is achieve via the graduated thimble and lever. The lever, used as a reducing mechanism, gives controlled leak rates ranging to 10-11 mbar l/s-1. Simple rugged design has produced a reliable valve which can be fitted to vacuum systems with absolute confidence.
The all metal leak valve by virtue of its design withstands bakeout temperatures associated with UHV systems without detriment to preformance.
