The DVE is a ow control valve which
controls the ow rate by means of an
adjustable constriction of the cross section
using a throttle spindle. It is available in
four sizes. The ow rate depends on the
pressure differential and the viscosity.
Starting with the throttle spindle in the fully
closed position when the ow is shut off,
the ow rate increases in accordance with
the appropriate curve as the control knob
is turned. The ow is controlled in both
directions. The scale and coloured scale
rings on the top of the control knob enable
accurate repeat setting.
