FD10-40 Flow Divider/Combiner

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 FD10-40 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.

Should circuit operation result in a blockage of either

➁ or ➃, the opposite port may

also close under certain conditions. Should this potential exist, consult the factory.

FEATURES

• Hardened parts for long life.

• Quiet, modulated response.

• Industry common cavity.
