1 into 2 Hydraulic Gear Flow Divider and Combiner, takes one flow and divides equally into 2 flows, fitted with differential reliefs.

One of the more difficult things to achieve in Hydraulics: is to make two cylinders extend & retract at the same speed.

Many things can cause this imbalance, lack of rigidity in the frame work, internal friction or resistance to flow through the hoses and fittings, different friction in the cylinder seals, weigh differentials on each cylinder, wind loads, even the slope or lay of the machine or mobile plant will allow gravity to pull down harder on one cylinder than the other.

A very accurate way (+/- 5% or less ) to do this is with a rotary gear flow divider, This hydraulic item mechanically forces the oil to divide at exactly the same rate. Please see brief explanation below.

One hydraulic line is connected to the inlet port of the geared flow divider, flow and pressure cause internal gears to rotate and divide oil up equally, the divided oil exits out of two separate outlet ports and these are in turn connected to the extend port on two cylinders. Maximum working pressure is 3,300-3,500psi. See specs.

When retracting cylinder oil flow is reversed and the two lines from each cylinder flow into the two inlet ports (formerly Outlet ports) the gears in flow divider reverse direction and oil is combined and flows out through the single outlet port (formerly the inlet port) .

This comes in various flow rates which you can pick from the drop box next to the price. It is important for accuracy to pick as close to flow as possible. This divider will work with both Single acting or double acting circuits.

It will take continuous pressure up to 220-240 bar /3300- 3500 PSI & differential 1800psi

Please note;

The 1FDF is a group 1 size so are cheaper.

The 2FDF series is a larger group 2 unit so that increases price. 2FDF units,
The outlet block on the 2FDF has anti cavitation check valves in them so if you hook up T/NS ports to tank this will allow oil to be sucked in if either outlet cavitates.
