The DVP is a manifold mounted flow control valve which
controls the flow rate by adjusting the cross-section. The flow rate is
therefore dependent on the pressure differential and viscosity. Starting with the throttle spindle in the fully closed
position, the flow rate increases in accordance with the appropriate curve as
the control knob is turned. The flow is controlled in both directions. The
scale and coloured rings on the top of the control knob enable accurate repeat
setting.
The DRVP is a manifold mounted flow control valve which
allows the same fine flow adjustment, but in one direction only. Unrestricted
flow in the reverse direction is via the built-in check valve (cracking
pressure 0.5 bar).
