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
conditions. 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.

Description
This range of flow divider/
combiner 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 variation.
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 synchronize
actuator movement. Flow
variation is within ±10% with
the maximum variation of
pressure and inlet flow and
under normal conditions will
be significantly less.
