DG-FDA FLOW DIVIDER / COMBINER VALVE, SPOOL TYPE
DESCRIPTION
10 size, 7/8-14 thread “Delta Series”, spool type, ow divider/combiner.
OPERATION
In the dividing mode, the DG-FDA will divert input ow from port (2) to ports (3) and (1), based on the ratio
specied, regardless of operating pressure. The DG-FDA will combine input ows from ports (3) and (1), to port
(2) by the same ratio. Should circuit operation result in a blockage of either (3) or (1), the opposite port may also
close under certain conditions. Should this potential exist, consult the factory.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
