A vacuum valve for high-vacuum applications.

This valve can be set up to allow the inflow of gas to two separate areas (or two different areas of the same vacuum system).

It can also be configured to allow two unique gasses to mix together in varying ratios via the flow control knobs. You can even use this valve to flush your system by pulling vacuum down off one line and then feeding in an inert gas through the other line to backfill your system.
