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 ● Pressure compensated to keep the two split flows at the same ratio regardless of pressure variations between them. A common application is to keep two cylinders (or motors) in close unison when loads on them are unequal. ● Pressure compensation in both 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. ● Flows from 55 to 140 L/min Specifications Maximum Rated Pressure: Maximum Total Flow: Ambient Temperature Range: Fluid Temperature Range: Hydraulic Fluid: Accuracy/ Tolerances: Porting: Materials: Fluid cleanliness: Weight: Mounting: 420 bar, 6000 psi Up to 140 L/min, 37 US gpm -30 to 100 °C, -22 to 212 °F -30 to 100 °C, -22 to 212 °F Mineral & Synthetic oils.

(14.5 - 37.0 US gpm). ● +/-1.5% accuracy between 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 ● Unequal division of the two split flows available. From 50/50% to 90/10%. ● Maximum 14 bar (200 psi) pressure drop at valves rated maximum flow (see page 3) ● The body is black polyester powder coated EN-GJS-500-7 iron. End plugs are zinc plated with clear trivalent passivation.

Typical Pressure Drop All tests completed with ISO32 mineral oil at 40˚C (32cst) 14 Valve Rated Flow 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...
