FDC140 Series

High Flow Divider Combiner

The FDC140 series hydraulic valve offers high ﬂow, high pressure, dividing and

combining with an excellent split ﬂow accuracy under varying loads.

The FDC140 will divide a single ﬂow into two separate ﬂows which will always be

in the same ratio to each other regardless of any pressure differential between

the two lines. If the ﬂow is reversed (e.g. return stroke of two cylinders) the

return ﬂows are held in the same ratio to each other and combined into a single

ﬂow, regardless of individual loads on the cylinders

A common application is to keep two cylinders (or motors) in close unison when

loads on them are unequal.

For example, access and lifting platforms, car ramps, tail lifts on municipal and

other heavy vehicles, continuous track such as snow clearing vehicles, road

rollers and harvesters.

 Features

● Pressure compensated to

keep the two split ﬂows at

the same ratio regardless of

pressure variations between

them.

● Pressure compensation in both

forward (divide) and reverse

(combine) ﬂows.

the two split ﬂows, based on

valve rated maximum ﬂow (see

page 3).

● A loading difference above

250 bar (3500 psi) between the

two split ﬂows may result in

reduced performance

ValveAccuracy

Division Accuracy.

The accuracy is speciﬁed as a percentage of the valves rated maximum ﬂow. The accuracy of +/-1.5% deﬁnes

a maximum difference between the two split ﬂows as 3% of the maximum ﬂow. The same is true for both

forward (divide) and reverse (combine) ﬂows.

For a valve with rated ﬂow size 100, the accuracy is calculated as +/-1.5% of its maximum ﬂow of 100 L/min

(26.4 US gpm). This equates to a maximum allowable difference between the two split ﬂows of 3.0 l/min (+/-1.5

L/min), or 0.8 US gpm (+/-0.4 US gpm).

If the ﬂow to the same valve is reduced to 70 L/min (18.5 US gpm), the accuracy is still speciﬁed as +/-1.5% of

its maximum ﬂow (100 L/min, 26.4 US gpm).

For a valve with 50/50 split ﬂow ratio, the two split ﬂows are equal, and ½ of the total ﬂow.

For a valve with 80/20 split ﬂow ratio, the total ﬂow is split with 80% going through A PORT & 20% going

through B PORT. The accuracy of +/-1.5% calculated from the valves rated maximum ﬂow is then added to

give a maximum variation of the two split ﬂows.
