Variable Leak Valves
A Seal Free From Friction, Seizing And Sheer
The Agilent Variable Leak Valve includes a movable piston with an optically flat sapphire that meets a captured metal gasket. This forms a seal completely free from friction, seizing, and shear. The sapphires movement is controlled through a threaded shaft-and-lever mechanism that provides a mechanical advantage of 13,000 to 1.
