Weight: DV 06 = 0.10 kg DRV 06 = 0.10 kg
DV 08 = 0.26 kg DRV 08 = 0.28 kg
DV 10 = 0.38 kg DRV 10 = 0.41 kg

DV 16 = 1.04 kg DRV 16 = 1.14 kg
The DV is an inline mounted ow control
valve which controls the ow by adjusting
the restriction of the cross-section. The
ow rate is therefore dependent on
the pressure differential and 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 on the lower edge of the
control knob enables accurate repeat
setting. The DRV is a ow control valve
with a reverse ow check which also
allows the same ne ow adjustment, but
in one direction only. Unrestricted ow
in the reverse direction is via the built-in
check valve.
