Cary offers
3 standard models of rotating
unions with a wide range of port
sizes and thread configurations.
Available are single flow,
double flow, and a special
compact double flow. Also
available are double flow
elbows, stationary feed tubes
and connecting hose assemblies.
The dependable, leakproof Cary
rotating union works on the face
sealing principle and
features precision mating carbon
seals and ceramic seats. The
surfaces have a surface of four
(4)rms and are lapped to obtain
a true flatness of two (2) light
bands or .000023 inch and
inspected by optical testing.
After assembly each union is
bench tested to assure no
leakage and is free of other
abnormalities before a Cary
label is applied.

Double Flow should be
specified when
applicable. |

The Cary Compact Double
Flow Union is specially
designed to fit into
limited areas. The
double flow
configuration is
achieved within the
standard O-series
outline dimensions. No
external double flow
elbow is required.
Except for the special
endcap, all components
are interchangeable with
the standard O-series
Union. |

"O-1/2" Series
Union |
|
|
|
The
O1/2 Series unions, like the
smaller O and R series have an
unobstructed flow path which
reduces the pressure loss and
minimizes the tendency for
mineral deposits to form. Very
high Cv's are achieved within a
modest overall size. This series
is available in stainless steel
only with high temp Viton seals.
It is used primarily for the
bottling industry and complete
rebuild kits are available. |

Cary
double flow unions are used when
the fluid introduced into
rotating cylinder, drum, or
shaft must be withdrawn from the
same side. The Cv for double
flow unions is primarily
determined by the feed tube. See
approximate values listed. |
