Description
Full range adjustable restric-
tive pressure compensated
flow control package with free
reverse flow.
Operation
This standard valve package
is used in a hydraulic circuit
where flow rates must be
constantly maintained, regard-
less of changes in upstream or
downstream pressure.
Also where a full range of flow
adjustments is required. It also
provides free reverse flow.
Features
Pressure compensation, full
flow range adjustment, alu-
minum in-line type housing,
Screw and knob adjustment
options. All components in the
package are true cartridges
and can be removed from the
housing without disturbing the
plumbing.
