Medium flow valve (1/4"). The fluid flow rate between its two connected chambers varies as the valve stem is rotated. (Note that the flow rate also depends on the pressure difference between the chambers. Such a valve may, for example, be used to "bleed" a mixture of gases through a trap to separate condensable and incondensable fractions.
