Sample Flow Unit
The sample flow unit is located in the middle section (body) of the valve between the vaporizer
and the actuator piston. It is isolated from the vaporizer and actuator by lens-shaped Teflon
gaskets. An adjustable adapter and Belleville washers position the Teflon gaskets with a
constant pressure to align the sample hole or groove with the sample connections, and to
compensate for temperature expansion and gasket wear.
