FDC3-20 - Flow Divider/Combiner
Pressure compensated, spool type, posi-traction
Up to 570 L/min (150 USgpm) • 210 bar (3000 psi)
Description
This is a pressure
compensated flow divider
/ combiner posi-traction
valve. This is ideal for use in
transmission systems where
the turning circle requires one
wheel to go faster than the
other or where rapid make up
is required between cylinders
at the end of stroke.
Operation
This valve is used in the
dividing mode. It will take the
inlet flow (port 3) and split the
flow to ports 2 and 4. In the
combining mode this valve will
take the inlet flows from ports
2 and 4 and combine them
into port 3 according to the
ratio specified.
Features
One valve synchronizes in both
directions. Matched spools
give high accuracy under
load and pressure imbalance
conditions.
