SN-FDA FLOW DIVIDER / COMBINER VALVE, SPOOL TYPE
DESCRIPTION
16 size, 1 5/16-12 thread “Super Series,” spool-type ow divider/combiner valve.
OPERATION
In the dividing mode, the SN-FDA will divert input ow from port (2) to ports (3) and (1), based on the ratio
specied, regardless of operating pressure. The SN-FDA will combine input ows from ports (3) and (1), to port
(2) by 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.
