FLOW CONTROLS
FD10-42 Flow Divider/Combiner w/ Anti-Stall Feature
DESCRIPTION
A screw-in, cartridge-style, spool-type fl ow divider/combiner. Optional fl ow dividing/
combining ratios are maintained regardless of system operating pressure conditions.
OPERATION
In the dividing mode, the FD10-42 will divert input fl ow from port ➂ to ports ➁ and ➃,
based on the ratio specifi ed, regardless of operating pressure.
The cartridge will combine input fl ows from ports
➁ and ➃.
The FD10-42 is designed to maintain a fl ow path to both combining ports
➁ and ➃
when one port is “free-wheeling.” This feature keeps hydraulic (parallel) motor drive
circuits from stalling in the combining mode only.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
