When
HEWI of Suhlendorf manufactured new apparatus for sample preparation
at an important refinery in Hamburg, the company specified
both Hoke and GO products as part of the equipment.
This included Gyrolok fittings and Hoke 2- and
3-way ball valves, which had already proved their worth in
this refinery over a number of years, in part used with Space
Saver Actuators Representing another breakthrough on an important
application, GO PR-1 and PR-7 series regulators were specified
by the company for the first time.

The
sample preparation apparatus has several functions. Water and
impurities existing in the production unit must be removed in
order that the analytical apparatus is not damaged and so that
the corresponding chemical analysis can be carried out in the
most accurate way.
In other apparatus the pressure has to be reduced
and flow has to be limited. By using a GO pressure regulator
in the circuit, a constant average pressure is guaranteed for the analysis.
Furthermore, by fitting Hoke 3-way ball valves,
it is also possible to calibrate the analysis unit by using
a calibration gas. |
