Several rotary valves on one pipe line.
Airflow passing a rotary valve in a pipe line does not
reduce capacity. Passing material through many rotary
valves in the same pipe line reduce capacity conside-
rably.
Therefore max. 3 rotary valves in line are recommen-
ded. With more than 3 rotary valves, a "by pass" can
be made.

General principles for
installation and use of pipes
and bends
Distance between bends.
There should be a minimum distance of 2M between
any flow direction change, i.e. between any bends.
With larger TRL blowers moving higher capacities,
longer distances are even better.
This does not apply if only air is blown through the
system.
Min. 2 m
Installation of telescopes.
Always ensure that telescopes are installed so that the
sharp edge points in the flow direction – not against. If
telescopes are installed in the wrong way, damage to
the material may occur.

Installation of bends.
Do not put 2 bends back to back, as this will cause
damage to the material and there will be a loss of
capacity.
It is recommended to use a heavier 1M pipe (OKR/
OKD) following each bend to compensate for wear.

Diverters.
When using diverters, the same applies as mentioned
above for bends, however, if space is narrow, 1 meter
between a bend and a diverter is recommended. If ne-
cessary, the installation of a bend following the diverter
in the outlet direction is acceptable, which will create
a considerably faster wear of the bend. Do not blow
material directly from a bend into the diverter, which
will create a fast wear of the diverter.
It is possible to blow in each direction and suck
through an OK160 diverter, type 122 000 690.
