FDC11-16 - Flow Divider/Combiner
Pressure compensated, spool type
Up to 140 L/min (37 USgpm) • 350 bar (5000 psi)
Description
This range of flow divider/com-
biner valves gives division of
input flow into two equal parts
and re-combination of flow in
the reverse direction. Pressure
compensation ensures that
whether dividing or combining,
equal flow is maintained over
a wide range of pressure varia-
tion. A typical use of these
valves is to divide a pump
flow to operate two actuators
(which may be under different
load conditions and at different
pressures) and to re-combine
the return flows to synchro-
nize actuator movement. Flow
variation is within ±10% with
the maximum variation of
pressure and inlet flow and
under normal conditions will
be significantly less.
Operation
Inlet flow passes through the
two matched orifices in the
spools, through the spools and
out of the radial holes in the
sleeve. The matched orifices
and the compensating springs
ensure that the flow is divided
equally, excess flow in either
direction causes the
spool to move and close the
radial holes in the sleeve until
equilibrium is restored. In the
reverse direction the spools
close together and regulate
the flow in through the radial
ports.
Features
One valve synchronizes in both
directions. Matched spools
give high accuracy under load
and pressure imbalance condi-
tions. Cartridge construction
gives versatility of application.
A valve may be fitted into a
line body, a custom designed
Hydraulic Integrated Circuit or
other hydraulic equipment.
