Figure 15.5 ICM flow actively regu-
lated.
A pressure compensated flow control valve is fitted to the ICM drain outlet. A suit-
able valve is the ICM-FC1 (see 2.1.2), but other ones can be used too. This has
the effect of a ``flow limiter’’, maintaining a constant flow rate even with a vary-
ing inlet pressure (provided this pressure stays above a minimum working value).
Below this pressure the valve is wide open so has little effect, i.e. the flow will be
less than the 200ml/min controlled value. This ``minimum working value’’ will
be typically 5-10 bar but will vary with viscosity. For these lower pressures a flow
control valve is not needed and other methods are better used to control flow as
previously described.
