The DVP is a manifold mounted ow
control valve which controls the ow
rate by adjusting the constriction of the
cross-section. The ow rate is therefore
dependent on the pressure differential and
viscosity. Starting with the control spindle
in the fully closed position, the ow rate
increases according to the relevant curve
as the number of turns of the control knob
is increased. The ow is controlled in
both directions. The DRVP is a manifold
mounted ow control valve which allows
the same ne ow adjustment, but in one
direction only. Unrestricted ow in the
reverse direction is via the built-in check
valve.
