FDC3-16 - Flow Divider/Combiner
Pressure compensated, spool type, posi-traction
Up to 152 L/min (40 USgpm) • 210 bar (3000 psi)
Description
This is a pressure
compensated flow divider /
combiner posi-traction screw
in cartridge 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
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.
